(c) Explanation of assignment limita-tions appearing in the frequency tableof paragraph (b) of this section:

(1) This frequency band is sharedwith and stations operating in this fre-quency band in this service are on asecondary basis to stations licensed inthe International Fixed Service andthe Maritime Mobile Service.

(2) This frequency band is sharedwith and stations operating in this fre-quency band in this service are on asecondary basis to the LORAN Naviga-tion System; all operations are limitedto radiolocation lands stations in ac-cordance with footnote US104, § 2.106 ofthis chapter.

(3) [Reserved](4) Non-Government radiolocation

service in this band is on a secondarybasis to stations in the Aeronautical

Radionavigation Service operating on1638 or 1708 kHz.

(5) Station assignments on fre-quencies in this band will be made sub-ject to the conditions that the maxi-mum output power shall not exceed 375watts and the maximum authorizedbandwidth shall not exceed 2 kHz.

(6) Because of the operation of sta-tions having priority on the same oradjacent frequencies in this or in othercountries, frequency assignments inthis band may either be unavailable ofmay be subject to certain technical ofoperational limitations. Therefore, ap-plications for frequency assignments inthis band shall include informationconcerning the transmitter outputpower; the type and directional charac-teristics of the antenna and the mini-mum hours of operation (GMT).

(7) This band is shared with the Dis-aster Communications Service (part 99)and operations are on a secondary basisto that service between local sunsetand local sunrise, or at any time dur-ing an actual or imminent disaster.Local sunrise and sunset times shall bederived from the 1946 American Nau-tical Almanac. Each frequency assign-ment in this band is on an exclusivebasis within the daytime primary serv-ice area to which assigned. The day-time primary service area is the areawhere the signal intensities are ade-quate for radiolocation purposes duringthe hours from sunrise to sunset fromall stations in the radiolocation systemof which the station in question is apart; that is, the primary service areaof the station coincides with the pri-mary service area of the system. Thenormal minimum geographical separa-tion between stations of different li-censees shall be at least 580 km. (360mi.) when the stations are operated onthe same frequency or on different fre-quencies separated by less than 3 kHz.Where geographical separation of lessthan 580 km. (360 mi.) is desired underthese circumstances it must be shownthat the desired separation will resultin protection ratio of at least 20 deci-bels throughout the daytime primaryservice area of other stations. Applica-tions in this band are placed on publicnotice in accordance with § 1.962 of thischapter. Where the number of appli-cants requesting authority to serve an


321


area exceeds the number of frequenciesavailable for assignment; or where itappears that fewer applicants or licens-ees than the number before it should begiven authority to serve a particulararea; or where it appears that an appli-cant, either directly or indirectly,seeks to use more than 25 kHz of theavailable spectrum space in this band,the applications may be designated forhearing.

(8) Frequencies in this band may onlybe assigned to radiolocation stationswhich are also assigned frequencies inthe 1605–1800 kHz band, provided theuse of frequencies in this band is nec-essary for the proper functioning of theparticular radiolocation system. Oper-ations in this band are on a secondarybasis to stations operating in accord-ance with the Commission’s table offrequency allocations contained in§ 2.106 of this chapter.

(9) This band is allocated to theRadiolocation Service on a secondarybasis to other fixed or mobile servicesand must accept any harmful inter-ference that may be experienced fromsuch services or from the industrial,scientific, and medical (ISM) equip-ment operating in accordance withpart 18 of this chapter. In the 2483.5–2500 MHz band, no applications for newor modification to existing stations toincrease the number of transmitterswill be accepted. Existing licensees asof July 25, 1985, or on a subsequent datefollowing as a result of submitting anapplication for license on or beforeJuly 25, 1985, are grandfathered andtheir operation is co-primary with theRadiodetermination Satellite Service.

(10) Speed measuring devices will notbe authorized in this band.

(11) This frequency band is sharedwith and is on a secondary basis to theMaritime Radionavigation Stations(part 80) and to the Government Radio-location Service.

(13) Operations in this band are lim-ited to survey operations using trans-mitters with a peak power not to ex-ceed 5 watts into the antenna.

(14) This frequency band is sharedwith and is on a secondary basis to theAeronautical Radionavigation Service

(part 87) and to the Government Radio-location Service.

(15) The non-Government Radio-location Service in this band is second-ary to the Maritime RadionavigationStations (part 80), the AeronauticalRadionavigation Service (part 87) andthe Government Radiolocation Service.

(16) This frequency band is sharedwith and is on a secondary basis to theMaritime Radionavigation Stations(part 80) and the Government Meteoro-logical Aids Service.

(17) Operation in this frequency bandis on a secondary basis to airborneDoppler radars at 8800 MHz.

(18) Radiolocation installations willbe coordinated with the GovernmentMeteorological Aids Service, and inso-far as practicable, will be adjusted tomeet the needs of that service.

(19) Operations in this band are on asecondary basis to the Amateur RadioService (part 97). Pulsed emissions areprohibited.

(20) This band is restricted to radio-location systems using type N0N emis-sion with a power not to exceed 40watts into the antenna.

(21) Non-Government radiolocationstations in the band are secondary tothe Government Radiolocation Service,the Amateur Radio Service and theAmateur-Satellite Service. Pulse-rang-ing radiolocation stations in this bandmay be authorized along the shorelinesof Alaska and the contiguous 48 states.Radiolocation stations using spreadspectrum techniques may be author-ized in the band 420–435 MHz for oper-ation within the contiguous 48 statesand Alaska. Also, stations using spreadspectrum techniques shall be limitedto a maximum output power of 50watts, shall be subject to the applica-ble technical standards in § 90.209 untilsuch time as more definitive standardsare adopted by the Commission andshall identify in accordance with§ 90.425(c)(3). Authorizations will begranted on a case-by-case basis; how-ever, operations proposed to be locatedwithin the zones set forth in § 90.177(e)should not expect to be accommodated.

(22) For frequencies 2455, 10,525, and24,125 MHz unmodulated continuouswave (NON) emission only shall be em-ployed and a frequency stability of atleast 0.2 percent shall be maintained.

Such stations shall be exempt from therequirements of §§ 90.403(c) and (f) and90.429.

(23) Devices designed to operate asfield disturbance sensors on fre-quencies between 2450 and 2500 MHzwith a field strength equal to or lessthan 50,000 microvolts per meter at 30meters, on a fundamental frequency,will not be licensed or certificated foruse under this part. Such equipmentmust comply with the requirements forfield disturbance sensors as set forth inpart 15 of this chapter.

(24) Devices designed to operate asfield disturbance sensors on fre-quencies between 10,500 and 10,550 MHzand between 24,050 and 24,250 MHz, withfield strength equal to or less than250,000 microvolts per meter at 30 me-ters, on the fundamental frequency,will not be licensed or certificated foruse under this part. Such equipmentmust comply with the requirements forfield disturbance sensors as set forth inpart 15 of this chapter.

(25) Station assignments on fre-quencies in this band will be made sub-ject to the conditions that the maxi-mum output power shall not exceed 375watts and the maximum authorizedbandwidth shall not exceed 1.0 kHz.

(26) Each frequency assignment inthis band is on an exclusive basis with-in the primary service area to whichassigned. The primary service area isthe area where the signal intensitiesare adequate for radiolocation purposesfrom all stations in the radiolocationsystem of which the station in questionis a part; that is, the primary servicearea of the station coincides with theprimary service area of the system.The normal minimum geographicalseparation between stations of dif-ferent licensees shall be at least 1931km (1200 miles) when the stations areoperated on the same frequency or ondifferent frequencies separated by lessthan 1.0 kHz. Where geographical sepa-ration of less than 1931 km (1200 miles)is requested under these cir-cumstances, it must be shown that thedesired separation will result in a pro-tection ratio of at least 20 decibelsthroughout the primary service area ofother stations.

(27) Notwithstanding the bandwidthlimitations otherwise set forth in this

section of the rules, wideband systemsdesiring to operate in this band mayuse such bandwidth as is necessary forproper operation of the system pro-vided that the field strength does notexceed 120 microvolts per meter persquare root Hertz (120 uv/m/Hz1⁄2) at 1.6km (1 mile). Such wideband operationsshall be authorized on a secondarybasis to stations operating within oth-erwise applicable technical standards.Applications for wideband systems inthis band will be accepted beginningDecember 15, 1985.

(28) Since the 1605–1705 kHz band hasbeen reallocated for AM broadcasting,no new assignments in the 1605–1705kHz portion of this band shall be madeafter September 30, 1985.

(29) Beginning July 1, 1987, licenseesof existing systems authorized fre-quencies in the 1605–1705 kHz portion ofthis band may request modification oftheir authorizations to change fre-quencies to the 1900–2000 kHz band.

(30) Until July 1, 1988, this band willbe available only for licensees of exist-ing systems operating in the 1605–1705kHz portion of the 1605–1715 kHz bandrequesting modification of their au-thorizations to change frequencies tothis band and for licensees of widebandsystems. On July 1, 1988, requests fornew station authorizations in this bandwill be accepted and, if necessary, willbe subject to the random selection pro-cedures outlined in § 1.972 of the Com-mission’s Rules.

(31) This frequency band is sharedwith and is on secondary basis to theFixed-Satellite Service and to the Gov-ernment’s Radiolocation, Space Re-search and Earth Exploration-SatelliteServices. After January 1, 2000, theGovernment’s Space Research andEarth Exploration-Satellite Servicesshall operate on a co-equal secondarybasis with the non-Government Radio-location Service, except that grand-fathered space stations in the Trackingand Data Relay Satellite System shallcontinue to be protected from harmfulinterference.

(d) Other additional frequencies avail-able. Radiolocation stations in thisservice may be authorized, on request,to use frequencies allocated exclusivelyto Federal Government stations, inthose instances where the Commission


323


finds, after consultation with the ap-propriate Government agency or agen-cies, that such assignment is necessaryor required for coordination with Gov-ernment activities.

§ 90.153 Transfer or assignment of sta-tion authorization.

A station authorization and therights it grants shall not be trans-ferred, assigned, or in any manner dis-posed of to any person, unless the Com-mission shall, after obtaining full in-formation, decide that the transfer, as-signment, or disposal is in the publicinterest, convenience or neccessity andgive its consent in writing. An appli-cant for voluntary transfer of controlor assignment under this section wherethe subject license was acquired by thetransferor or assignor through a sys-tem of random selection shall, togetherwith its application for transfer of con-

trol or assignment, file with the Com-mission the associated contracts forsale, option agreements, managementagreements, or other documents dis-closing the total consideration that theapplicant would receive in return forthe transfer or assignment of its li-cense. This information should includenot only a monetary purchase price,but also any future, contingent, in-kind, or other consideration (e.g., man-agement or consulting contracts eitherwith or without an option to purchase;below-market financing). The assigneeis responsible for ascertaining that thestation facilities are and will remain incompliance with the terms and condi-tions of the authorization to be as-signed.

(a) Application required. The assignoror transferor of a commercial mobileradio license under this part must filean application for approval of assign-ment or transfer of control (Commis-sion Form 490). In the case of involun-tary assignment, such applicationmust be filed no later than thirty (30)days after the event causing the as-signment. The assignee or transfereemust file a report qualifying it as acommercial mobile radio provider(Commission Form 430) unless a cur-rent report is already on file with theCommission.

(1) Forbearance from pro forma assign-ments and transfers of control. Licenseesthat are telecommunications carriersas defined in 47 U.S.C. 153 are subjectto streamlined procedures for proforma, i.e., non-substantial, transfersand assignments.

(2) A pro forma assignee or transfereeis not required to seek prior FCC ap-proval for the transaction, but mustnotify the FCC no later than 30 daysafter the event causing the assignmentor transfer, either by filing an FCCForm 490 or in letter form. If a letter issubmitted, it must contain a certifi-cation that the transfer or assignmentis non-substantial and, together withall previous non-substantial trans-actions, does not involve a change inthe licensee’s ultimate control. A sin-gle letter may be filed for a transfer orassignment of control of more than oneauthorization if each authorization af-fected is identified by call sign in the


332

47 CFR Ch. I (10–1–98 Edition)§ 90.155

letter. Licensees must concurrently up-date ownership information on theirFCC Form 430, if necessary.

(b) Notification of completion. Assign-ments and transfers of control of com-mercial mobile radio licenses must becompleted within sixty (60) days ofCommission approval, except those li-censees subject to the streamlined pro-cedures of paragraph (a)(1) of this sec-tion. The assignee or transferee mustnotify the Commission by letter of thedate of completion of the assignmentor transfer of control. If an assignmentor transfer of control is not completedwithin this time, the assignor or trans-feror must so notify the Commissionby letter, and the assignee or trans-feree must submit the authorization(s)to the Commission for cancellation orrequest an extension of time to com-plete the assignment or transfer of con-trol. If the assignment or transfer ofcontrol is not completed, the author-ization(s) remain with the assignor ortransferor.

(c) Partial assignment of authorization.If the authorization for some, but notall, of the facilities of a commercialmobile radio station is assigned to an-other party, voluntarily or involuntar-ily, such action is a partial assignmentof authorization.

(1) To request Commission approvalof a partial assignment of authoriza-tion, the following must be filed in ad-dition to the forms required by para-graph (a) of this section:

(i) The assignor must notify the Com-mission (Commission Form 600) of thefacilities to be deleted from its author-ization upon completion of the assign-ment.

(ii) The assignee must apply for au-thority (Commission Form 600) to oper-ate a new station including the facili-ties for which authorization is as-signed, or to modify the assignee’s ex-isting station to include the facilitiesfor which authorization was assigned.

(2) Partial assignments must be com-pleted within sixty (60) days of Com-mission approval. If an approved par-tial assignment is not completed with-in this time, the assignor must notifythe Commission (Commission Form600), and the assignee must submit theauthorization(s) to the Commission for

cancellation or request an extension oftime to complete the assignment. Ifthe assignment is not completed, theauthorization(s) remain with the as-signor.

(d) Limitations. The Commission maydeny applications for assignment of au-thorization or consent to transfer ofcontrol of a commercial mobile radiolicense if:

(1) The Commission is unable tomake the public interest determina-tions required under the Communica-tions Act with respect to both partiesto the assignment or transfer; or

(2) The authorization was obtainedfor the principal purpose of speculationor profitable resale, rather than provi-sion of commercial mobile radio serv-ices to the public.

333


§ 90.353, must construct and place in op-eration a sufficient number of base sta-tions that utilize multilateration tech-nology (see paragraph (e) of this sec-tion) to provide multilateration loca-tion service to one-third of the EA’spopulation within five years of initiallicense grant, and two-thirds of thepopulation within ten years. In dem-onstrating compliance with the con-struction and coverage requirements,the Commission will allow licensees toindividually determine an appropriatefield strength for reliable service, tak-ing into account the technologies em-ployed in their system design and otherrelevant technical factors. At the fiveand ten year benchmarks, licenseeswill be required to file a map and othersupporting documentation showingcompliance with the coverage require-ments.

(e) A multilateration LMS stationwill be considered constructed andplaced in operation if it is built in ac-cordance with its authorized param-eters and is regularly interacting withone or more other stations to providelocation service, using multilaterationtechnology, to one or more mobileunits. Specifically, LMSmultilateration stations will only beconsidered constructed and placed inoperation if they are part of a systemthat can interrogate a mobile, receivethe response at 3 or more sites, com-pute the location from the time of ar-rival of the responses and transmit thelocation either back to the mobile orto a subscriber’s fixed site.

SPECIAL RULES GOVERNING FACILITIESUSED TO PROVIDE COMMERCIAL MO-BILE RADIO SERVICES

SOURCE: 59 FR 59959, Nov. 21, 1994, unlessotherwise noted.

NOTE: The following rules (§§ 90.160 through90.169) govern applications, licensing, and op-eration of radio facilities in the 220–222 MHz(subpart T), Business Radio (Subpart D), 929–930 MHz Paging (subpart P), and Specialized


335


Mobile Radio (Subpart S) services that areused to provide commercial mobile radioservices (see §§ 20.3 and 20.9 of this chapter).Compliance with the rules relating to appli-cations and licensing of facilities on paging-only channels in the Business Radio Service(see § 90.75(c)(10)) and 929–930 MHz pagingchannels (see § 90.494(a),(b)) is not requiredprior to August 10, 1996. Compliance with § 990.168 is also not required prior to August 10,1996 for reclassified commercial mobile radioservice providers who are to be regulated asprivate carriers until August 10, 1996 as pro-vided in the Second Report and Order in GNDocket No. 93–252, 9 FCC Rcd 2348 (1994),paras. 280–284. The licensing and operation ofradio facilities in the 220–222 MHz (SubpartT), Business Radio (Subpart D), 929–930 MHzPaging (Subpart P), and Specialized MobileRadio (Subpart S) services that are used toprovide commercial mobile radio services arealso subject to rules elsewhere in this partthat apply generally to Private Land MobileRadio Services. In the case of any conflictbetween rules set forth in §§ 90.160 through90.169 and other rules in this part, §§ 90.160through 90.169 apply.

§ 90.160 Public notice.Periodically, the Commission will

issue Public Notices listing major fil-ings and other information of publicsignificance concerning commercialmobile radio services licensed underthis part. Categories of Public Noticelistings are as follows:

(a) Accepted for filing. Acceptance forfiling of all applications and majoramendments thereto.

(b) Actions. Commission actions onpending applications previously listedas accepted for filing.

(c) Informative listings. Informationthat the Commission, in its discretion,believes to be of public significance.Such listings do not create any rightsto file oppositions or other pleadings.

§ 90.161 Amendment or dismissal ofapplications.

(a) Amendment. Pending applicationsconcerning facilities for providing com-mercial mobile radio services may beamended as a matter of right if suchapplications have not been designatedfor hearing or listed in a Public Noticefor a random selection or competitivebidding process, except as provided inparagraphs (a)(1) and (a)(2) of this sec-tion. If a petition to deny or other for-mal objection has been filed, a copy ofany amendment (or other filing) must

be served on the petitioner. If the Com-mission has issued a Public Noticestating that the application appears tobe mutually exclusive with another ap-plication (or applications), a copy ofany amendment (or other filing) mustbe served on any such mutually exclu-sive applicant (or applicants).

(1) Amendments to applications thatresolve mutual exclusivity may be filedat any time, subject to the require-ments of § 90.162.

(2) Amendments to applications des-ignated for hearing may be allowed bythe presiding officer and amendmentsto applications selected in a randomselection process may be allowed bythe Commission for good cause shown.In such instances, a written petitiondemonstrating good cause must be sub-mitted and served upon the parties ofrecord.

(b) Dismissal. The Commission maydismiss any application for authoriza-tion, assignment of authorization, orconsent to transfer of control of a com-mercial mobile radio facility.

(1) Upon request by the applicant;Any applicant may request that its ap-plication be returned or dismissed. Arequest for the return of an applicationafter it has been listed on Public No-tice as tentatively accepted for filing isconsidered to be a request for dismissalof that application without prejudice.

(i) If the applicant requests dismissalof its application with prejudice, theCommission will dismiss the applica-tion with prejudice.

(ii) If the applicant requests dismis-sal of its application without prejudice,the Commission will dismiss that ap-plication without prejudice, unless

(A) The application has been des-ignated for comparative hearing;

(B) It has been selected in a randomselection process; or

(C) It is an application for which theapplicant submitted the winning bid ina competitive bidding process. If theapplicant requests dismissal of its ap-plication for which it submitted thewinning bid in a competitive biddingprocess, the Commission will dismissthat application with prejudice. If theapplicant requests dismissal of its ap-plication after that application hasbeen designated for comparative hear-ing or selected in a random selection


336

47 CFR Ch. I (10–1–98 Edition)§ 90.162

process, it may submit a written peti-tion requesting that the dismissal bewithout prejudice. Such petition mustdemonstrate good cause, comply with§ 90.162 of this part, and be served uponall parties of record. The Commissionmay grant such petition and dismissthe application without prejudice ordeny the petition and dismiss the ap-plication with prejudice.

(2) If the application is untimelyfiled; The Commission may dismisswithout prejudice any application thatis prematurely or filed late, includingany application filed prior to the open-ing date or after the closing date of afiling window, or after the cut-off datefor a mutually exclusive applicationfiling group.

(3) If the application is mutually ex-clusive with another application thatis selected or granted in accordancewith the rules in this part; The Com-mission may dismiss any mutually ex-clusive application:

(i) For which the applicant did notsubmit the winning bid in a competi-tive bidding process;

(ii) That is included in a random se-lection process but is not granted; or

(iii) That receives comparative con-sideration in a hearing but is notgranted by order of the presiding offi-cer.

(4) For failure to prosecute; The Com-mission may dismiss applications forfailure of the applicant to prosecute orfor failure of the applicant to respondsubstantially within a specified timeperiod to official correspondence or re-quests for additional information. Suchdismissal will generally be withoutprejudice if the failure to prosecute orrespond occurred prior to designationof the application for comparativehearing or prior to selection of the ap-plication in a random selection proc-ess, but may be with prejudice in casesof non-compliance with § 90.162. Dismis-sal will generally be with prejudice ifthe failure to prosecute or respond oc-curred after designation of the applica-tion for comparative hearing or afterselection of the application in a ran-dom selection process. The Commissionmay dismiss applications with preju-dice for failure of the applicant to com-ply with requirements related to acompetitive bidding process.

(5) If the requested spectrum is notavailable; The Commission may dis-miss any application that requestsspectrum which is unavailable because:

(i) It was previously assigned to an-other licensee on an exclusive basis orcannot be assigned to the applicantwithout causing interference; or

(ii) Reasonable efforts have beenmade to coordinate the proposed facil-ity with foreign administrations underapplicable international agreements,and an unfavorable response (harmfulinterference anticipated) has been re-ceived.

(6) If the application is found to bedefective. Such dismissal may be‘‘without prejudice,’’ meaning that theCommission may accept from the ap-plicant another application for thesame purpose at any later time, or‘‘with prejudice,’’ meaning that theCommission will not accept from theapplicant another application for thesame purpose for a period of one yearfollowing the date of the dismissal ac-tion taken by the Commission. Unlessotherwise provided in this part, a dis-missed application will not be returnedto the applicant. The Commission maydismiss without prejudice applicationsthat it finds to be defective. An appli-cation for authorization or assignmentof authorization is defective if:

(i) It is unsigned or incomplete withrespect to required answers to ques-tions, informational showings, or othermatters of a formal character; or

(ii) It requests an authorization thatwould not comply with the Commis-sion’s Rules and does not contain a re-quest for waiver of these rule(s), or inthe event that the Commission deniessuch a waiver request, does not containan alternative proposal that fully com-plies with the rules.

§ 90.162 Agreements to dismiss appli-cations, amendments, or pleadings.

(a) Parties that have filed an applica-tion concerning facilities used to pro-vide commercial mobile radio servicesthat is mutually exclusive with one ormore other applications, and thenenter into an agreement to resolve themutual exclusivity by withdrawing orrequesting dismissal of the applicationor an amendment thereto, must obtain

(d) No person shall make or receiveany payments in exchange for with-drawing a threat to file or refrainingfrom filing a petition against an appli-cation. For purposes of this section, re-imbursement by an applicant of the le-gitimate and prudent expenses of a po-tential petitioner or objector, incurredreasonably and directly in preparing tofile a petition to deny, will not be con-sidered to be payment for refrainingfrom filing a petition to deny or an in-formal objection. Payments made di-rectly to a potential petitioner or ob-jector, or a person related to a poten-tial petitioner or objector, to imple-ment non-financial promises are pro-hibited unless specifically approved bythe Commission.

(e) For purposes of this section:(1) Affidavits filed pursuant to this

section must be executed by the filingparty, if an individual, a partner hav-ing personal knowledge of the facts, ifa partnership, or an officer having per-sonal knowledge of the facts, if a cor-poration or association.

(2) Applications, petitions to deny,informal objections, and other plead-ings are deemed to be pending beforethe Commission from the time the ap-plication or petition to deny is filedwith the Commission until such timeas an order of the Commission grant-ing, denying, or dismissing the applica-tion, petition to deny, informal objec-tion, or other pleading is no longer sub-ject to reconsideration by the Commis-sion or to review by any court.

(3) ‘‘Legitimate and prudent ex-penses’’ are those expenses reasonablyincurred by a party in preparing to file,filing, prosecuting and/or settling itsapplication, petition to deny, informalobjection, or other pleading for whichreimbursement is sought.

(f) Notwithstanding the provisions ofthis section, any payments made or re-ceived in exchange for withdrawing ashort-form application for an FCC au-thorization awarded through competi-tive bidding shall be subject to the re-strictions set forth in section § 1.2105(c)of this chapter.

[59 FR 59959, Nov. 21, 1994, as amended at 62FR 11636, Mar. 12, 1997]

§ 90.163 Petitions to deny, responsivepleadings.

Petitions to deny any major filingconcerning facilities used to providecommercial mobile radio services maybe filed by parties able to demonstratestanding to file such petitions. Respon-sive pleadings to such petitions may befiled in accordance with the provisionsof this section.

(a) Content and requirements. Peti-tions to deny and responsive pleadingsmust:

(1) Clearly identify the pertinentmajor filing(s);

(2) Comply with all applicable re-quirements of §§ 1.41 through 1.52 of thischapter;

(3) Contain specific allegations offact which, except for facts of which of-ficial notice may be taken, are sup-ported by affidavit of a person or per-sons with personal knowledge thereof,and which are sufficient to dem-onstrate that the petitioner (or re-spondent) is a party in interest andthat a grant or other Commission ac-tion regarding the major filing wouldbe inconsistent with the public inter-est;

(4) Be filed within 30 days after thedate of the Public Notice listing themajor filing; and

(5) Contain a certificate of serviceshowing that a copy has been mailed tothe applicant no later than the date offiling with the Commission.

(c) Dismissal. The Commission may,by letter, dismiss any petition to deny

a major filing if the petition does notcomply with the requirements of thissection or § 90.161. The reason(s) for thedismissal must be stated in the letter.When a petition to deny is dismissed,any related responsive pleadings alsoare dismissed.

§ 90.164 Classification of filings asmajor or minor.

Applications and amendments to ap-plications are classified as major orminor when such filings concern facili-ties used to provide commercial mobileradio services. Categories of major andminor filings are listed in section 309 ofthe Communications Act of 1934, asamended (47 U.S.C. 309). In general, amajor filing is a request for a Commis-sion action that has the potential toaffect parties other than the applicant.The following are major filings:

(a) Initial station authorization. Fil-ings for an initial authorization as de-fined in § 90.165(d)(2) are major.

(b) Ownership or control change. Fil-ings are major if they specify a sub-stantial change in beneficial ownershipor control (de jure or de facto), unlesssuch change is involuntary or if the fil-ing merely amends an application toreflect a change in ownership or con-trol that has already been approved bythe Commission.

(c) Renewal. Applications for renewalof authorizations are major.

(d) Environmental. Filings are majorif they request authorization for a fa-cility that would have a significant en-vironmental effect, as defined by§§ 1.1301 through 1.1319 of this chapter.

(e) In the Specialized Mobile RadioService, in addition to filings listed inparagraphs (a) through (d) of this sec-tion, filings are major if they:

(1) Request a change in frequency;(2) Request an authorization that

would increase the effective radiatedpower or antenna height above averageterrain in any azimuth from an exist-ing transmitter authorized to the filer;

(3) Request an authorization thatwould relocate an existing fixed trans-mitter;

(4) Amend a pending application tochange a requested frequency;

(5) Amend a pending application in away that would increase the proposedeffective radiated power or antenna


339


height above average terrain in anyazimuth from an existing transmitterauthorized to the filer;

(6) Amend a pending application tochange the location of a fixed trans-mitter from that previously proposedin the application; or

(7) Amend a pending application forwhich pre-filing coordination was re-quired to change the technical proposalsubstantially from that which was co-ordinated with other users.

§ 90.165 Procedures for mutually ex-clusive applications.

Mutually exclusive commercial mo-bile radio service applications are proc-essed in accordance with the rules inthis section, except for mutually exclu-sive applications for licenses in the 220–220 MHz service and the 929–930 MHzPaging service, which are processed inaccordance with the rules in subpart Pand subpart T of this part.

Two or more pending applications aremutually exclusive if the grant of oneapplication would effectively precludethe grant of one or more of the othersunder Commission rules governing theservices involved.

(a) Separate applications. Any appli-cant that files an application knowingthat it will be mutually exclusive withone or more applications should not in-clude in the mutually exclusive appli-cation a request for other channels orfacilities that would not, by them-selves, render the application mutuallyexclusive with those other applica-tions. Instead, the request for suchother channels or facilities should befiled in a separate application.

(b) Filing groups. Pending mutuallyexclusive applications are processed infiling groups. Mutually exclusive appli-cations in a filing group are given con-current consideration. The Commissionmay dismiss as defective (pursuant to§ 90.162) any mutually exclusive appli-cations(s) whose filing date is outsideof the date range for inclusion in thefiling group. The types of filing groupsused in day-to-day application process-ing are specified in paragraph (c)(3) ofthis section. A filing group is one ofthe following types:

(1) Renewal filing group. A renewal fil-ing group comprises a timely-filed ap-plication for renewal of an authoriza-

tion and all timely-filed mutually ex-clusive competing applications.

(2) Same-day filing group. A same-dayfiling group comprises all mutually ex-clusive applications whose filing dateis the same day, which is normally thefiling date of the first-filed applica-tions(s).

(3) Thirty-day notice and cut-off filinggroup. A 30-day notice and cut-off filinggroup comprises mutually exclusiveapplications whose filing date is nolater than thirty (30) days after thedate of the Public Notice listing thefirst-filed application(s) (according tothe filing dates) as acceptable for fil-ing.

(4) Window filing group. A window fil-ing group comprises mutually exclu-sive applications whose filing date iswithin an announced filing window. Anannounced filing window is a period oftime between and including two spe-cific dates, which are the first and lastdates on which applications (or amend-ments) for a particular purpose may beaccepted for filing. In the case of a one-day filing window, the two dates arethe same. The dates are made known tothe public in advance.

(c) Procedures. Generally, the Com-mission may grant one application in afiling group of mutually exclusive ap-plications and dismiss the other appli-cation(s) in the filing group that areexcluded by the grant, pursuant to§ 90.162.

(1) Selection methods. In selecting theapplication to grant, the Commissionmay use competitive bidding, randomselection, or comparative hearings, de-pending on the type of applications in-volved.

(2) Dismissal of applications. The Com-mission may dismiss any application ina filing group that is defective or oth-erwise subject to dismissal under§ 90.162, either before or after employ-ing selection procedures.

(3) Type of filing group used. Except asotherwise provided in this part, thetype of filing group used in processingof two or more mutually exclusive ap-plications depends on the purpose(s) ofthe applications.

(i) If one of the mutually exclusiveapplications is a timely-filed applica-tion for renewal of an authorization, arenewal filing group is used.


340

47 CFR Ch. I (10–1–98 Edition)§ 90.165

(ii) If any mutually exclusive appli-cation filed on the earliest filing dateis an application for modification andnone of the mutually exclusive applica-tions is a timely-filed application forrenewal, a same-day filing group isused.

(iii) If all of the mutually exclusiveapplications filed on the earliest filingdate are applications for initial author-ization, a 30-day notice and cut-off fil-ing group is used.

(4) Disposition. If there is only one ap-plication in any type of filing group,the Commission may grant that appli-cation and dismiss without prejudiceany mutually exclusive applicationsnot in the filing group. If there is morethan one mutually exclusive applica-tion in a filing group, the Commissiondisposes of these applications as fol-lows:

(i) Applications in a renewal filinggroup. All mutually exclusive applica-tions in a renewal filing group are des-ignated for comparative considerationin a hearing.

(ii) Applications in a 30-day noticeand cut-off filing group.

(A) If all of the mutually exclusiveapplications in a 30-day notice and cut-off filing group are applications for ini-tial authorization, the Commission ad-ministers competitive bidding proce-dures in accordance with subpart Q ofpart 1 of this chapter. After such proce-dures, the application of the successfulbidder may be granted and the otherapplications may be dismissed withoutprejudice.

(B) If any of the mutually exclusiveapplications in a 30-day notice and cut-off filing group is an application formodification or an application for fa-cilities, the Commission may attemptto resolve the mutual exclusivity by fa-cilitating a settlement between the ap-plicants. If a settlement is not reachedwithin a reasonable time, the Commis-sion may designate all applications inthe filing group for comparative con-sideration in a hearing. In this event,the result of the hearing disposes all ofthe applications in the filing group.

(iii) Applications in a same-day filinggroup. If there are two or more mutu-ally exclusive applications in a same-day filing group, the Commission mayattempt to resolve the mutual exclu-

sivity by facilitating a settlement be-tween the applicants. If a settlement isnot reached within a reasonable time,the Commission may designate all ap-plications in the filing group for com-parative consideration in a hearing. Inthis event, the result of the hearingdisposes all of the applications in thefiling group.

(iv) Applications in a window filinggroup. Applications in a window filinggroup are processed in accordance withthe procedures for a 30-day notice andcut-off filing group in paragraph(c)(4)(ii) of this section.

(d) Terminology. For the purposes ofthis section, terms have the followingmeanings:

(1) The ‘‘filing date’’ of an applica-tion is the date on which that applica-tion was received in a condition ac-ceptable for filing or the date on whichthe most recently filed major amend-ment to that application was received,whichever is later, excluding majoramendments in the following cir-cumstances:

(i) The major amendment reflectsonly a change in ownership or controlfound by the Commission to be in thepublic interest;

(ii) The major amendment as re-ceived is defective or otherwise foundunacceptable for filing; or

(iii) The application being amendedhas been designated for hearing and theCommission or the presiding officer ac-cepts the major amendment.

(2) An ‘‘application for initial author-ization’’ is:

(i) Any application requesting an au-thorization for a new system or sta-tion;

(ii) Any application requesting au-thorization for an existing station tooperate on an additional channel, un-less the additional channel is for pairedtwo-way radiotelephone operation, isin the same frequency range as the ex-isting channel(s), and will be oper-ationally integrated with the existingchannel(s) such as by trunking; or

(iii) any application requesting au-thorization for a new transmitter at alocation more than 2 kilometers (1.2miles) from any existing transmittersof the applicant licensee on the re-quested channel or channel block.


341


(3) An ‘‘application for modification’’is any application other than an appli-cation for initial authorization or re-newal.

§ 90.166 Grants of applications.Applications for a commercial mobile

radio service authorization under thispart may be granted thirty (30) daysafter the issuance date of a Pubic No-tice listing an application or the latestfiled major amendment thereto as ac-ceptable for filing.

(a) Criteria for grants. The Commis-sion grants applications without ahearing if, after examination of the ap-plication and consideration of any peti-tions or other pleadings and of suchother matters as it may officially no-tice, the Commission finds that:

(1) A grant will serve the public in-terest, convenience, and necessity;

(2) There are no substantial and ma-terial questions of fact presented;

(3) The applicant is eligible andqualified under applicable Commissionregulations and policies;

(4) The application is acceptable forfiling, and complies with the Commis-sion rules and other applicable require-ments;

(5) The application has not been des-ignated for a hearing after being se-lected in a random selection process;

(6) There are no applications entitledto comparative consideration with theapplication being granted; and

(7) Operation of the proposed stationwould not cause interference to any au-thorized station(s).

(b) Grant of petitioned applications.The Commission may grant, without aformal hearing, applications againstwhich petitions to deny have beenfiled. If any petition(s) to deny arepending (i.e., have not been dismissedpursuant to § 90.161 or withdrawn bythe petitioner) when an application isgranted, the Commission shall denythe petition(s) and issue a concisestatement of the reason(s) for the de-nial, disposing of all substantive issuesraised in the petitions.

(c) Partial and conditional grants. TheCommission may grant applications inpart, and/or subject to conditions otherthan those normally applied to author-izations of the same type. When theCommission does this, it will inform

the applicant of the reasons therefor.Such partial or conditional grants arefinal unless the Commission revises itsaction in response to a petition for re-consideration. Such petitions for re-consideration must be filed by the ap-plicant within thirty days after thedate of the letter or order stating thereasons for the partial or conditionalgrant, and must reject the partial orconditional grant and return the in-strument of authorization.

(d) Designation for hearing. The Com-mission may designate applications fora hearing, specifying with particularitythe matters in issue, if, after consider-ation of the application, any petitionsor other pleadings, and other matterswhich it may officially notice, theCommission is unable to make one ormore of the findings listed in para-graph (a) of this section. The Commis-sion may grant, deny, or take other ac-tion with respect to applications des-ignated for a hearing.

§ 90.167 Time in which a station mustcommence service.

(a) Unless otherwise specified in thispart, all 220–222 MHz, private carrierpaging, Industrial/Business Pool, andSMR licensees must commence servicewithin twelve (12) months from thedate of grant or the authorization can-cels automatically and must be re-turned to the Commission.

(b) For purposes of this section, astation licensed to provide commercialmobile radio service is not consideredto have commenced service unless itprovides service to at least one unaf-filiated party.

(c) Application for extension of timeto commence service may be made onCommission Form 600. Extensions oftime must be filed prior to the expira-tion of the construction period. Exten-sions will be granted only if the li-censee shows that the failure to com-mence service is due to causes beyondhis or her control. No extensions willbe granted for delays caused by lack offinancing, lack of site availability, forthe assignment or transfer of control ofan authorization, or for failure to time-ly order equipment. If the licensee or-ders equipment within 90 days of the li-cense grant, a presumption of due dili-gence is created.


342

47 CFR Ch. I (10–1–98 Edition)§ 90.168

(d) An application for modification ofan authorization (under construction)at the existing location does not ex-tend the initial construction period. Ifadditional time to commence service isrequired, a request for such additionaltime must be submitted on Commis-sion Form 600, either separately or inconjunction with the submission of theCommission Form 600 requesting modi-fication.

§ 90.169 Construction prior to grant ofapplication.

Applicants may construct facilitiesprior to grant of their applications,subject to the provisions of this sec-tion, but must not operate such facili-ties until the Commission grants anauthorization. If the conditions statedin this section are not met, applicantsmust not begin to construct facilities.

(a) When applicants may begin con-struction. An applicant may begin con-struction of a facility thirty-five (35)days after the date of the Public Noticelisting the application for that facilityas acceptable for filing.

(b) Notification to stop. If the Commis-sion for any reason determines thatconstruction should not be started orshould be stopped while an applicationis pending, and so notifies the appli-cant, orally (followed by written con-firmation) or in writing, the applicantmust not begin construction or, if con-struction has begun, must stop con-struction immediately.

(c) Assumption of risk. Applicants thatbegin construction pursuant to thissection before receiving an authoriza-tion do so at their own risk and haveno recourse against the United Statesfor any losses resulting from:

(1) Applications that are not granted;(2) Errors or delays in issuing Public

Notices;(3) Having to alter, relocate, or dis-

mantle the facility; or(4) Incurring whatever costs may be

necessary to bring the facility intocompliance with applicable laws, orCommission rules and orders.

Subpart H—Policies Governing theAssignment of Frequencies

§ 90.171 Scope.This subpart contains detailed infor-

mation concerning the policies underwhich the Commission assigns fre-quencies for the use of licensees underthis part, frequency coordination pro-cedures, and procedures under which li-censees may cooperatively share radiofacilities.

§ 90.173 Policies governing the assign-ment of frequencies.

(a) The frequencies which ordinarilymay be assigned to stations in theservices governed by this part are list-ed in subparts B, C and F of this part.Frequencies other than those listed insubparts B and C may be assigned inthe 150–174 MHz, 421–430 MHz, 450–470MHz, and 470–512 MHz bands, providedsuch applications are accompanied by ashowing of frequency coordination inaccordance with the requirements of§ 90.175. Except as otherwise specifi-cally provided in this part, frequenciesassigned to land mobile stations areavailable on a shared basis only andwill not be assigned for the exclusiveuse of any licensee.

(b) All applicants and licensees shallcooperate in the selection and use of

frequencies in order to reduce inter-ference and make the most effectiveuse of the authorized facilities. Licens-ees of stations suffering or causingharmful interference are expected tocooperate and resolve this problem bymutually satisfactory arrangements. Ifthe licensees are unable to do so, theCommission may impose restrictionsincluding specifying the transmitterpower, antenna height, or area or hoursof operation of the stations concerned.Further the use of any frequency at agiven geographical location may be de-nied when, in the judgment of the Com-mission, its use in that location is notin the public interest; the use of anyfrequency may be restricted as to spec-ified geographical areas, maximumpower, or such other operating condi-tions, contained in this part or in thestation authorization.

(c) Frequencies allocated for FederalGovernment radio stations under Exec-utive order of the President may be au-thorized for the use of stations in theseservices upon appropriate showing bythe applicant that such assignment isnecessary for inter-communicationwith government stations or requiredfor coordination with activities of theFederal Government, and where theCommission finds, after consultationwith the appropriate government agen-cy or agencies, that such assignment isnecessary.

(d) The radio facilities authorizedunder this part are intended for use inconnection with and as an adjunct tothe primary governmental or businessactivities of the licensee.

(e) Persons requesting authority tooperate in the band 25–50 MHz shouldrecognize that this band is shared withvarious services in other countries andthat harmful interference may becaused by the propagation of signals inthis band from distant stations. Noprotection from such harmful inter-ference generally can be expected.

(f) Applications for stations in the150–174 MHz and 421–512 MHz bands foroperation on frequencies 15 kHz or lessremoved from existing stations in thesame geographic area will be grantedbased upon a recommendation from theapplicable frequency coordinator asspecified in §§ 90.20(c)(2) and 90.35(b)(2).


346

47 CFR Ch. I (10–1–98 Edition)§ 90.173

(g) In the states of Alaska and Ha-waii, and in areas outside the continen-tal limits of the United States and theadjacent waters, the frequencies above150.8 MHz which are listed elsewhere inthis part as available for assignment tobase stations or mobile stations in theIndustrial/Business Pool are also avail-able for assignment to operationalfixed stations in the Industrial/Busi-ness Pool on a secondary basis.

(h) In the Public Safety Pool, basestations may be authorized to operateon a secondary basis on frequenciesbelow 450 MHz which are available tomobile stations.

(i) In the 450–470 MHz band, the fre-quencies are ordinarily assigned inpairs, with the mobile station transmitfrequency 5 MHz above the paired basestation transmit frequency. In the 470–512 MHz band, the frequencies are ordi-narily assigned in pairs with the mo-bile station transmit frequency 3 MHzabove the paired base station transmitfrequency. In the Industrial/BusinessPool, in the 150 MHz band, the fre-quencies subject to § 90.35(c)(6) may beassigned in pairs with the separationbetween base and mobile frequenciesbeing 5.26 MHz. A mobile station maybe assigned the frequency which wouldnormally be assigned to a base stationfor single-frequency operation. How-ever, this single-frequency operationmay be subject to interference thatwould not occur to a two-frequencysystem.

(j) [Reserved](k) This paragraph is only applicable

to entities with Finder’s Preference re-quests pending before the Commissionas of July 29, 1998. Notwithstandingany other provisions of this part, anyeligible person shall be given a disposi-tive preference for a channel assign-ment on an exclusive basis in the 220–222 MHz, 470–512 MHz, and 800/900 MHz(except on frequencies designated ex-clusively for SMR service) bands bysubmitting information that leads tothe recovery of channels in thesebands. Recovery of such channels mustresult from information provided re-garding the failure of existing licenseesto comply with the provisions of

§§ 90.155, 90.157, 90.629, 90.631 (e) or (f), or90.633 (c) or (d).

(l) In the 150–174 MHz band, exceptwhere otherwise specifically provided,authorizations for frequencies thatwere available prior to August 18, 1995will be granted with channelbandwidths of 25 kHz or less. Author-izations for all other frequencies inthis band will be granted with channelbandwidths of 12.5 kHz or less (i.e., inthe Public Safety Pool, frequenciessubject to §§ 90.20 (d)(27) and (d)(44), andin the Industrial/Business Pool, fre-quencies subject to §§ 90.35 (c)(30) and(c)(33)).

(m) In the 421–512 MHz band, exceptwhere otherwise specifically provided,authorizations for frequencies thatwere available prior to August 18, 1995will be granted with channelbandwidths of 25 kHz or less. New au-thorizations for frequencies 12.5 kHz re-moved from these frequencies will bemade for channel bandwidths of 12.5kHz or less (i.e., in the Public SafetyPool, frequencies subject to§ 90.20(d)(27) and in the Industrial/Busi-ness Pool, frequencies subject to§ 90.35(c)(30)). Authorizations for fre-quencies 6.25 kHz removed from thesefrequencies will be granted with chan-nel bandwidths of 6.25 kHz or less (i.e.,in the Public Safety Pool, frequenciessubject to § 90.20(d)(44), and in the In-dustrial/Business Pool, frequencies sub-ject to § 90.35(c)(33)).

(n) Any recovered channels in the 800MHz SMR service will revert automati-cally to the holder of the EA licensewithin which such channels are in-cluded. If there is no EA licensee for re-covered channels, such channels will beretained by the Commission for futurelicensing.

§ 90.175 Frequency coordination re-quirements.

Except for applications listed inparagraph (f) of this section, each ap-plication for a new frequency assign-ment, for a change in existing facilitiesas listed in § 90.135(a), or for operationat temporary locations in accordancewith § 90.137, must include a showing offrequency coordination as set forthbelow. An application to reinstate a li-cense expired for more than thirty (30)days will be considered as a request fora new frequency assignment.

(a) Frequency coordinators may re-quest, and applicants are required toprovide, all appropriate technical in-formation, system requirements, andjustification for requested station pa-rameters when such information is nec-essary to identify and recommend themost appropriate frequency. Addition-ally, applicants bear the burden of pro-ceeding and the burden of proof in re-questing the Commission to overturn acoordinator’s recommendation.

(b) For frequencies between 25 and 470MHz: A statement is required from theapplicable frequency coordinator asspecified in §§ 90.20(c)(2) and 90.35(b)(2)recommending the most appropriatefrequency. The coordinator’s rec-ommendation may include commentson technical factors such as power, an-tenna height and gain, terrain, andother factors which may serve to mini-mize potential interference.

(c) For frequencies above 800 MHz:When frequencies are shared by morethan one service, concurrence must beobtained from the other applicable cer-tified coordinators.

(d) For frequencies in the 450–470 MHzband: When used for secondary fixedoperations, frequencies shall be as-signed and coordinated pursuant to§ 90.261.

(e) For frequencies between 470 and 512MHz, 806–824/851–869 MHz, and 896–901/935–940 MHz: A statement is requiredfrom the applicable coordinator rec-ommending specific frequencies thatare available for assignment in accord-ance with the loading standards andmileage separations applicable to thespecific radio serve, frequency pool, orcategory of user involved.

(f) For frequencies in the 929–930 MHzband. A statement from the coordina-

tor recommending the most appro-priate frequency. For applicationsunder § 90.495, the coordinator’s state-ment must verify that the proposedsystem meets the requirements of thatsection.

(g) Any recommendation submittedin accordance with paragraphs (a), (c),(d), or (e) of this section is advisory incharacter and is not an assurance thatthe Commission will grant a license foroperation on that frequency. Therefore,applicants are strongly advised not topurchase radio equipment operating onspecific frequencies until a valid au-thorization has been obtained from theCommission.

(h) Applications for facilities nearthe Canadian border north of line A oreast of line C in Alaska may require co-ordination with the Canadian govern-ment. See § 1.955 of this chapter.

(i) The following applications neednot be accompanied by evidence of fre-quency coordination:

(1) Applications for frequencies below25 MHz.

(2) Applications for a Federal Govern-ment frequency.

(3) Applications for frequencies in the72–76 MHz band except for mobile fre-quencies subject to § 90.35(c)(77).

(4) Applications for a frequency to beused for developmental purposes.

(5) Applications in the Industrial/Business Pool requesting a frequencydesignated for itinerant operationonly.

(6) Applications in the RadiolocationService.

(7) [Reserved](8) Applications for frequencies listed

in the SMR tables contained in §§ 90.617and 90.619.

(9) Applications indicating license as-signments such as change in owner-ship, control or corporate structure ifthere is no change in technical param-eters.

(10) Applications for mobile stationsoperating in the 470–512 MHz band orabove 800 MHz if the frequency pair isassigned to a single system on an ex-clusive basis in the proposed area of op-eration.

(11) Applications for add-on base sta-tions in multiple licensed systems op-erating in the 470–512 MHz band orabove 800 MHz if the frequency pair is

(a) Frequencies below 470 MHz. Withinone business day of making a frequencyrecommendation, each frequency coor-dinator must notify and provide the in-formation indicated in paragraph (e) ofthis section to all other frequency co-ordinators who are also certified to co-ordinate that frequency.

(1) The applicable frequency coordi-nator for each frequency is specified inthe coordinator column of the fre-quency tables of §§ 90.20(c)(3) and90.35(b)(3).

(2) For frequencies that do not speci-fy any frequency coordinator, all cer-tified in-pool coordinators must be no-tified.

(3) For frequencies that are sharedbetween the Public Safety Pool and theIndustrial/Business Pool (frequenciessubject to §§ 90.20(d)(7), (d)(25), (d)(34),or (d)(46) in the Public Safety Pool, andsubject to §§ 90.35(c)(13), (c)(25), or (d)(4)in the Industrial/Business Pool), allcertified coordinators of both poolsmust be notified.

(b) Frequencies in the 470–512 MHzband. Within one business day of mak-ing a frequency recommendation, eachfrequency coordinator must notify andprovide the information indicated inparagraph (e) of this section to allother certified frequency coordinatorsin the Public Safety Pool and the In-dustrial/Business Pool.

(c) Each frequency coordinator mustalso notify all other certified in-poolcoordinators on any day that the fre-

quency coordinator does not make anyfrequency recommendations.

(d) Notification must be made to allcoordinators at approximately thesame time and can be made using anymethod that ensures compliance withthe one business day requirement.

(e) At a minimum the following in-formation must be included in each no-tification:

(1) Name of applicant;(2) Frequency or frequencies rec-

ommended;(3) Antenna locations and heights;(4) Effective radiated power (ERP);(5) Type(s) of emissions;(6) Description of the service area;

and(7) Date and time of recommenda-

tion.(f) Upon request, each coordinator

must provide any additional informa-tion requested from another certifiedcoordinator regarding a pending rec-ommendation that it has processed buthas not yet been granted by the Com-mission.

(g) It is the responsibility of each co-ordinator to insure that its frequencyrecommendations do not conflict withthe frequency recommendations of anyother frequency coordinator. Should aconflict arise, the affected coordinatorsare jointly responsible for taking ac-tion to resolve the conflict, up to andincluding notifying the Commissionthat an application may have to be re-turned.

§ 90.177 Protection of certain radio re-ceiving locations.

This section pertains to applicationsfor new or modified authorizations inthe vicinity of the National Radio As-tronomy Observatory, Green Bank, Po-cahontas County, WV; the Naval RadioResearch Observatory, Sugar Grove,Pendleton County, WV; the Arecibo Ob-servatory, which is part of the Na-tional Astronomy and Ionosphere Cen-ter, located near Arecibo, PR; theTable Mountain Radio Receiving Zone,Boulder County, CO.; the Federal Com-munications Commission monitoringstations; and other protected sites.

(a) Any applicant for a new perma-nent base or fixed station, or for a


349


modification of an existing authoriza-tion which would change the fre-quency, power, antenna height, direc-tivity, or location within the bound-aries described in paragraph (b) of thissection shall notify the Director, Na-tional Radio Astronomy Observatory,P.O. Box 2, Green Bank, WV 24944, inwriting, of the technical parameters ofthe proposal.

(1) The notification shall be madeprior to, or simultaneously with thefiling of the application with the Com-mission.

(2) The notification shall state thegeographical coordinates of the an-tenna, antenna height, antenna direc-tivity, proposed frequency, type ofemission, and effective radiated power.

(3) After receipt of such applications,the Commission will allow a period of20 days for comments or objections inresponse to the notifications indicated.If an objection to the proposed oper-ation is received during the 20-day pe-riod from the National Radio Astron-omy Observatory for itself or on behalfof the Naval Radio Research Observ-atory, the Commission will consider allaspects of the problem and take what-ever action is deemed appropriate.

(4) The provisions of this paragraphdo not apply to applications for mobile,temporary base, or temporary fixedstations.

(b) The area of concern for the Na-tional Radio Astronomy Observatoryor the Naval Radio Research Observ-atory is the area bounded by 39°15′ N.on the north, 78°30′ W. on the east,37°30′ N. on the south, and 80°30′ W. onthe west.

(c) Protection for Table MountainRadio Receiving Zone, Boulder County,Colorado. Applicants for a station au-thorization to operate in the vicinityof Boulder County, Colorado under thispart are advised to give due consider-ation, prior to filing applications, tothe need to protect the Table MountainRadio Receiving Zone from harmful in-terference. These are the research lab-oratories of the Department of Com-merce, Boulder County, CO. To preventdegradation of the present ambientradio signal level at the site, the De-partment of Commerce seeks to ensurethat the field strengths of any radiatedsignals (excluding reflected signals) re-

ceived on this 1800 acre site (in the vi-cinity of coordinates 40°07′50′′ N Lati-tude, 105° 14′40′′ W Longitude) resultingfrom new assignments (other than mo-bile stations) or from the modificationor relocation of existing facilities donot exceed the following values:

Frequency range

Fieldstrength

(millivolt permeter) in

authorizedbandwidthof service

Power fluxdensity 1

(dBW persquare

meter) inauthorizedbandwidthof service

Below 540 kHz ........................... 10 65.8540 to 1600 kHz ........................ 20 59.81.6 to 470 MHz .......................... 10 65.8470 to 890 MHz ......................... 30 56.2Above 890 MHz ......................... 1 85.8

1 Equivalent values of power flux density are calculated as-suming free space characteristic impedance of 376.7=120πohms.

(1) Advance consultation is rec-ommended particularly for those appli-cants who have no reliable data whichindicates whether the field strength orpower flux density figures in the abovetable would be exceeded by their pro-posed radio facilities (except mobilestations). In such instances, the follow-ing is a suggested guide for determin-ing whether coordination is rec-ommended:

(i) All stations within 2.4 km (1.5statute miles);

(ii) Stations within 4.8 km (3 statutemiles) with 50 watts or more effectiveradiated power (ERP) in the primaryplane of polarization in the azimuthaldirection of the Table Mountain RadioReceiving Zone;

(iii) Stations within 16 km (10 statutemiles) with 1 kW or more ERP in theprimary plane of polarization in the az-imuthal direction of the Table Moun-tain Receiving Zone;

(iv) Stations within 80 km (50 statutemiles) with 25 kW or more ERP in theprimary plane of polarization in the az-imuthal direction of the Table Moun-tain Receiving Zone.

(2) Applicants concerned are urged tocommunicate with the Radio Fre-quency Management Coordinator, De-partment of Commerce, Research Sup-port Services, NOAA R/E5X2, BoulderLaboratories, Boulder, CO 80303; tele-phone (303) 497–6548, in advance of filingtheir applications with the Commis-sion.

47 CFR Ch. I (10–1–98 Edition)§ 90.177

(3) The Commission will not screenapplications to determine whether ad-vance consultation has taken place.However, applicants are advised thatsuch consultation can avoid objectionsfrom the Department of Commerce orproceedings to modify any authoriza-tion which may be granted which, infact, delivers a signal at the site in ex-cess of the field strength specifiedherein.

(d) Protection for Federal Commu-nications Commission monitoring sta-tions:

(1) Applicants in the vicinity of anFCC monitoring station for a radio sta-tion authorization to operate newtransmitting facilities or changedtransmitting facilities which would in-crease the field strength produced overthe monitoring station over that pre-viously authorized are advised to giveconsideration, prior to filing applica-tions, to the possible need to protectthe FCC stations from harmful inter-ference. Geographical coordinates ofthe facilities which require protectionare listed in § 0.121(c) of the Commis-sion’s Rules. Applications for stations(except mobile stations) which willproduce on any frequency a direct wavefundamental field strength of greaterthan 10 mV/m in the authorized band-width of service (¥65.8 dBW/m2 powerflux density assuming a free spacecharacteristic impedance of 120 timespi, or 377, ohms) at the referenced co-ordinates, may be examined to deter-mine extent of possible interference.Depending on the theoretical fieldstrength value and existing root-sum-square or other ambient radio field sig-nal levels at the indicated coordinates,a clause protecting the monitoring sta-tion may be added to the station au-thorization.

(2) In the event that calculated valueof expected field exceeds 10 mV/m(¥65.8 dBW/m2) at the reference coordi-nates, or if there is any questionwhether field strength levels might ex-ceed the threshold value, advance con-sultation with the FCC to discuss anyprotection necessary should be consid-ered. Prospective applicants may com-municate with: Chief, Compliance andInformation Bureau, Federal Commu-nications Commission, Washington, DC20554, Telephone (202) 632–6980.

(3) Advance consultation is suggestedparticularly for those applicants whohave no reliable data which indicateswhether the field strength or powerflux density figure indicated would beexceeded by their proposed radio facili-ties (except mobile stations). In suchinstances, the following is a suggestedguide for determining whether an ap-plicant should coordinate:

the following conditions and limita-tions:

(a) Persons may share a radio stationonly on frequencies for which theywould be eligible for a separate author-ization.

(b) The licensee of the shared radiostation is responsible for assuring thatthe authorized facility is used only bypersons and only for purposes consist-ent with the requirements of this rulepart.

(c) Participants in the sharing ar-rangement may obtain a license fortheir own mobile units (including con-trol points and/or control stations forcontrol of the shared facility), or theymay use mobile stations, and controlstations or control points authorized tothe licensee.

(d) If the licensee shares the land sta-tion on a non-profit, cost shared basisto the licensee, this shared use must bepursuant to a written agreement be-tween the licensee and each participantwhich sets out (1) the method of oper-ation, (2) the components of the systemwhich are covered by the sharing ar-rangements, (3) the method by whichcosts are to be apportioned, and (4) ac-knowledgement that all shared trans-mitter use must be subject to the li-censee’s control. These agreementsmust be kept as part of the stationrecords.

(e) If the land station which is beingshared is interconnected with the pub-lic switched telephone network, theprovisions of § 90.477 et seq. apply.

(f) Above 800 MHz, shared use on afor-profit private carrier basis is per-mitted only by SMR, Private CarrierPaging, and LMS licensees. See sub-parts M, P, and S of this part.

(g) The provisions of this section donot apply to licensees authorized toprovide commercial mobile radio serv-ice under this part.

§ 90.205) that overlap a circle with ra-dius 113 km (70 mi.) from the proposedbase station. Alternatively, applicantsmay submit an engineering analysisbased upon generally accepted engi-neering practices and standards whichdemonstrates that the service area ofthe trunked system does not overlapany existing stations whose serviceareas overlap a circle with radius 113km (70 mi.) from the proposed base sta-tion.

(iii) The consensual agreementsamong licensees must specifically statethe terms agreed upon and a statementmust be submitted to the Commissionindicating that all licensees have con-sented to the use of trunking. If a li-censee has agreed to the use oftrunking, but later decides against theuse of trunking, the licensee may re-quest that the licensee(s) of thetrunked system reconsider the use oftrunking. If the licensee is unable toreach an agreement with the li-censee(s) of the trunked system, the li-censee may request that the Commis-sion consider the matter and assign itanother channel. New licensees willonly be assigned the same channel as atrunked system, if the new licenseereaches an agreement with the li-censee(s) of the trunked system.

(c) Trunking of systems licensed onpaging-only channels or licensed in theRadiolocation Service (subpart F) isnot permitted.

operating on either channel 4 or 5, orfrom the post office of a community inwhich such channels are assigned butnot in operation, the fixed station shallbe authorized only if there are fewerthan 100 family dwelling units (as de-fined by the U.S. Bureau of the Cen-sus), excluding units 112 or more km (70mi.) distant from the TV antenna site,located within a circle centered at thelocation of the proposed fixed station.The radius shall be determined by useof the following chart entitled, ‘‘Chartfor Determining Radius From FixedStation in 72–76 MHz Band to Inter-ference Contour Along Which 10 Per-cent of Service From Adjacent ChannelTelevision Station Would Be De-stroyed.’’ Two charts are available, onefor Channel 4, and one for Channel 5.The Commission may, however, in aparticular case, authorize the locationof a fixed station within a circle con-taining 100 or more family dwellingunits upon a showing that:

(i) The proposed site is the only suit-able location.

(ii) It is not feasible, technically orotherwise, to use other available fre-quencies.

(iii) The applicant has a plan to con-trol any interference that might de-velop to TV reception from his oper-ations.

(iv) The applicant is financially ableand agrees to make such adjustmentsin the TV receivers affected as may benecessary to eliminate any inter-ference caused by his operations.

(v) All applications seeking authorityto operate with a separation of lessthan 16 km (10 mi.) will be returnedwithout action.

(b) The following criteria governs theauthorization and use of frequencies inthe 72–76 MHz band by mobile stationsin the Industrial/Business Pool.

(1) Mobile operation on frequencies inthe 72–76 MHz band is subject to thecondition that no interference iscaused to the reception of televisionstations operating on Channel 4 or 5.Interference will be considered to occurwhenever reception of a regularly usedtelevision signal is impaired by signalsradiated by stations operating under

these rules in the 72 to 76 MHz band re-gardless of the quality of such recep-tion or the strength of the signal used.In order to minimize the hazard of suchinterference, it shall be the duty of thelicensee to determine whether inter-ference is being caused to television re-ception, wherever television receiversother than those under the control ofthe licensee, are located within 31 m.(100 ft.) of any point where the stationslicensed under these rules may be oper-ated. In any case, it shall be the re-sponsibility of the licensee to correct,at its own expense, any such inter-ference and if the interference cannotbe eliminated by the application ofsuitable techniques, the operation ofthe offending transmitter shall be sus-pended. If the complainant refuses topermit the licensee to apply remedialtechniques which demonstrably willeliminate the interference without im-pairment of the original reception, thelicensee is absolved of further respon-sibility.

(2) The maximum transmitter outputpower that will be authorized is 1 watt;and each station authorized will beclassified and licensed as a mobile sta-tion. Any units of such a station, how-ever, may be used to provide the oper-ational functions of a base or fixed sta-tion. The antennas of transmitters op-erating on these frequencies must bedirectly mounted or installed upon thetransmitting unit: Except that whenpermanently installed aboard a vehi-cle, antenna and transmitter may beseparated as required for conveniencein mounting. Horizontal polarizationwill not be allowed; and the gain of an-tennas employed shall not exceed thatof a halfwave dipole. The maximumbandwidth that will be authorized is 20kHz. Tone control transmissions arepermitted.

(c) Radio remote control of models ispermitted on frequencies 10 kHz re-moved from these frequencies author-ized for fixed and mobile operations inthe 72–76 MHz band. Remote control op-erations are secondary to operation offixed and mobile stations as providedfor in this section.

§ 90.305 Location of stations.(a) The transmitter site(s) for base

station(s), including mobile relay sta-tions, shall be located not more than 80km. (50 mi.) from the geographic centerof the urbanized area listed in § 90.303.

(b) Mobile units shall be operatedwithin 48 km. (30 mi.) of their associ-ated base station or stations. Suchunits may not be operated aboard air-craft in flight except as provided for in§ 90.315(i).

(c) Control stations must be locatedwithin the area of operation of the mo-bile units.

(d) Base and control stations shall belocated a minimum of 1.6 km. (1 mi.)from local television stations operat-ing on UHF TV channels separated by2, 3, 4, 5, 7, and 8 TV channels from thetelevision channel in which the basestation will operate.

§ 90.307 Protection criteria.The tables and figures listed in

§ 90.309 shall be used to determine theproper power (ERP) and antenna heightof the proposed land mobile base sta-tion and the proper power (ERP) forthe associated control station (controlstation antenna height shall not exceed31 m. (100 ft.) above average terrain(AAT)).

(a) Base stations operating on thefrequencies available for land mobileuse in any listed urbanized area andhaving an antenna height (AAT) lessthan 152 m. (500 ft.) shall afford protec-tion to co-channel and adjacent chan-nel television stations in accordancewith the values set out in tables A andE of this subpart, except for Channel 15in New York, NY, and Cleveland, OH,and Channel 16 in Detroit, MI, whereprotection will be in accordance withthe values set forth in tables B and E.

(b) For base stations having antennaheights between 152–914 meters (500–3,000 ft.) above average terrain, the ef-fective radiated power must be reducedbelow 1 kilowatt in accordance withthe values shown in the power reduc-

tion graph in Figure A, except forChannel 15 in New York, NY, andCleveland, OH, and Channel 16 in De-troit, MI, where the effective radiatedpower must be reduced in accordancewith Figure B. For heights of morethan 152 m. (500 ft.) above average ter-rain, the distance to the radio path ho-rizon will be calculated assumingsmooth earth. If the distance so deter-mined equals or exceeds the distance tothe Grade B contour of a co-channelTV station, (Grade B contour definedin § 73.683(a)) an authorization will notbe granted unless it can be shown thatactual terrain considerations are suchas to provide the desired protection atthe Grade B contour, or that the effec-tive radiated power will be further re-duced so that, assuming free space at-tenuation, the desired protection atthe Grade B contour will be achieved.

(c) Mobile units and control stationsoperating on the frequencies availablefor land mobile use in any given urban-ized area shall afford protection to co-channel and adjacent channel tele-vision stations in accordance with thevalues set forth in table C and para-graph (d) of this section except forChannel 15 in New York, NY, andCleveland, OH, and Channel 16 in De-troit, MI, where protection will be inaccordance with the values set forth intable D and paragraph (d) of this sec-tion.

(d) The minimum distance between aland mobile base station which has as-sociated mobile units and a protectedadjacent channel television station is145 km (90 miles) .

(e) The television stations to be pro-tected (co-channel, adjacent channel,IM, and IF) in any given urbanizedarea, in accordance with the provisionsof paragraphs (a), (b), (c), and (d) ofthis section, are identified in the com-mission’s publication ‘‘TV stations tobe considered in the preparation of Ap-plications for Land Mobile Facilities inthe Band 470–512 MHz.’’ The publicationis available at the offices of the Fed-eral Communications Commission atWashington, DC or upon the request ofinterested persons.

47 CFR Ch. I (10–1–98 Edition)§ 90.309

§ 90.309 Tables and figures.(a) Directions for using the tables. (1)

Using the method specified in § 73.611 orcharts or maps of suitable scale, deter-mine the distances (i) between the pro-posed land mobile base station and theprotected cochannel television stationand (ii) between the proposed land mo-bile base station and the protected ad-jacent channel television station. If theexact mileage does not appear in tableA for protected cochannel televisionstations (or table B for Channel 15 inNew York and Cleveland and channel 16in Detroit) or table E for protected ad-jacent channel television stations, thenext lower mileage separation figure isto be used.

(2) Entering the proper table at themileage figure found in paragraph(a)(1) of this section, find opposite, aselection of powers that may be usedfor antenna heights ranging from 15 m(50 ft) to 152.5 m (500 ft) (AAT). If theexact antenna height proposed for theland mobile base station does not ap-pear in the proper table, use the powerfigure beneath the next greater an-tenna height.

(3) The lowest power found using thetables mentioned in paragraphs (a)(1)and (a)(2) of this section is the maxi-mum power that may be employed bythe proposed land mobile base station.

(4) In determining the average ele-vation of the terrain, the elevations be-tween 3.2 km (2 mi) and 16 km (10 mi)from the antenna site are employed.Profile graphs shall be drawn for aminimum of eight radials beginning atthe antenna site and extending 16 km(10 mi). The radials should be drawnstarting with true north. At least oneradial should be constructed in the di-rection of the nearest cochannel and

adjacent channel UHF television sta-tions. The profile graph for each radialshall be plotted by contour intervals offrom 12.2 m (40 ft) to 30.5 m (100 ft) and,where the data permits, at least 50points of elevation (generally uni-formly spaced) should be used for eachradial. For very rugged terrain 61 m(200 ft) to 122 m (400 ft) contour inter-vals may be used. Where the terrain isuniform or gently sloping, the smallestcontour interval indicated on the topo-graphic chart may be used. The aver-age elevation of the 12.8 km (8-mile)distance between 3.2 km (2 mi) and 16km (10 mi) from the antenna siteshould be determined from the profilegraph for each radial. This may be ob-tained by averaging a large number ofequally spaced points, by using a pla-nimeter, or by obtaining the medianelevation (that exceeded by 50 percentof the distance) in sectors and averag-ing those values. In the preparation ofthe profile graphs, the elevation orcontour intervals may be taken fromU.S. Geological Survey TopographicMaps, U.S. Army Corps of EngineersMaps, or Tennessee Valley AuthorityMaps. Maps with a scale of 1:250,000 orlarger (such as 1:24,000) shall be used.Digital Terrain Data Tapes, providedby the National Cartographic Institute,U.S. Geological Survey, may be uti-lized in lieu of maps, but the number ofdata points must be equal to or exceedthat special above. If such maps arenot published for the area in question,the next best topographic informationshould be used.

(5) Applicants for base stations in theMiami, FL, urbanized area may, in lieuof calculating the height of averageterrain, use 3 m (10 ft) as the averageterrain height.

§ 90.313 Frequency loading criteria.

(a) Except as provided for in para-graph (b) of this section, the maximumchannel loading on frequencies in the470–512 MHz band is as follows:

(1) 50 units for systems eligible in thePublic Safety Pool (see § 90.20(a)).

(2) 90 units for systems eligible in theIndustrial/Business Pool (see § 90.35(a)).

(b) If a licensee has exclusive use of afrequency, then the loading standardsin paragraph (a) of this section, may beexceeded. If it is a shared channel, theloading standards can be exceeded uponsubmission of a signed statement by allthose sharing the channel agreeing tothe increase.

(c) A unit is defined as a mobiletransmitter-receiver. Loading stand-ards will be applied in terms of thenumber of units actually in use or tobe placed in use within 8 months fol-lowing authorization. A licensee will berequired to show that an assigned fre-quency pair is at full capacity before itmay be assigned a second or additionalfrequency pair. Channel capacity maybe reached either by the requirementsof a single licensee or by several userssharing a channel. Until a channel isloaded to capacity it will be availablefor assignment to other users in thesame area. A frequency pair may be re-assigned at distances 64 km. (40 mi.), 32km. (20 mi.) for Channel 15, Chicago;Channel 20, Philadelphia; and Channel17, Washington, or more from the loca-tion of base stations authorized on thatpair without reference to loading atthe point of original installation. Fol-lowing authorization, the licensee shallnotify the Commission either during orat the close of the 8 month period ofthe number of units in operation. Inthe Industrial Radio Services, if thebase station facility is to be used bymore than a single licensee, the fre-quency assigned to it will not be reas-signed for use by another facility with-in 64 km. (40 mi.) or 32 km. (20 mi.)where applicable for a period of 12months, Provided, That the facility isconstructed within 90 days from thedate of the first grant, meets the load-ing standards to at least 50 percent

within 9 months, and meets all loadingstandards within 12 months.

NOTE: As an example of the use of tables 1and 2, assume an offshore station located 290km (180 mi) from TV Channel 17 located inBude, Miss. with an antenna height of 30.5 m(100 ft). Table 1 allows this station to operatewith 250 W ERP. Now assume the shore sta-tion communicating with the offshore sta-tion is 48 km (30 mi) from the offshore sta-tion and 241 km (150 mi) from Bude, Miss.The shore station antenna height is 152.5 m(500 ft) above ground. The shore station willbe allowed the same ERP as the offshore sta-tion (250 W) in the direction of the offshorestation. Table 2 indicates that the effectiveradiated power in a sector <±> 221⁄2° from theline joining the shore antenna to Bude, Miss.

can only be 15 W. Consequently, a directionalantenna must be used whose minimum front-to-back ratio over this 45° sector must be atleast 12.2 dB. (250 W forward power to 15 Wrearward power is a power ratio of 16.6 or 12.2dB).

(i) The vehicle location update rates;(ii) Specific transmitter modulation

techniques used;(iii) For codes and timing scheme: A

table of bit sequences and their alpha-numeric or indicator equivalents, and astatement of bit rise time, bit trans-mission rates, bit duration, and inter-val between bits;

(iv) A statement of amplitude-versus-time of the interrogation and reply for-mats, and an example of a typical mes-sage transmission and any synchroniz-ing pulses utilized.

(4) A plan to show the implementa-tion schedule during the initial licenseterm.

(b) LMS stations are exempted fromthe identification requirements of§ 90.425; however, the Commission mayimpose automatic station identifica-tion requirements when determined to

be necessary for monitoring and en-forcement purposes.

§ 90.353 LMS operations in the 902–928MHz band.

LMS systems may be authorizedwithin the 902–928 MHz band, subject tothe conditions in this section. LMS li-censees are required to maintain what-ever records are necessary to dem-onstrate compliance with these provi-sions and must make these recordsavailable to the Commission upon re-quest:

(a) LMS operations will not cause in-terference to and must tolerate inter-ference from industrial, scientific, andmedical (ISM) devices and radio-location Government stations that op-erate in the 902–928 MHz band.

(b) LMS systems are authorized totransmit status and instructional mes-sages, either voice or non-voice, so longas they are related to the location ormonitoring functions of the system.

(c) LMS systems may utilize storeand forward interconnection, where ei-ther transmissions from a vehicle orobject being monitored are stored bythe LMS provider for later trans-mission over the public switched net-work (PSN), or transmissions receivedby the LMS provider from the PSN arestored for later transmission to the ve-hicle or object being monitored. Real-time interconnection between vehiclesor objects being monitored and thePSN will only be permitted to enableemergency communications related toa vehicle or a passenger in a vehicle.Such real-time, interconnected com-munications may only be sent to or re-ceived from a system dispatch point orentities eligible in the Public Safety orSpecial Emergency Radio Services. Seesubparts B and C of this part.

(d) Multilateration LMS systems willbe authorized on a primary basis with-in the bands 904–909.75 MHz and 921.75–927.25 MHz. Additionally,multilateration and non-multilateration systems will share the919.75–921.75 MHz band on a co-equalbasis. Licensing will be on the basis ofEconomic Areas (EAs) formultilateration systems, with one ex-clusive EA license being issued for eachof these three sub-bands. Except as pro-vided in paragraph (f) of this section,


402

47 CFR Ch. I (10–1–98 Edition)§ 90.355

multilateration EA licensees may beauthorized to operate on only one ofthe three multilateration bands withina given EA. Additionally, EAmultilateration LMS licenses will beconditioned upon the licensee’s abilityto demonstrate through actual fieldtests that their systems do not causeunacceptable levels of interference to47 CFR part 15 devices.

(e) Multilateration EA-licensed sys-tems and grandfathered AVM systems(see § 90.363) are authorized on a sharedbasis and must cooperate in the selec-tion and use of frequencies in accord-ance with Section 90.173(b).

(f) Multilateration EA licensees maybe authorized to operate on both the919.75–921.75 MHz and 921.75–927.25 MHzbands within a given EA (see§ 90.209(b)(10)).

(g) Multilateration LMS systemswhose primary operations involve theprovision of vehicle location services,may provide non-vehicular locationservices.

(h) Non-multilateration stations areauthorized to operate on a shared, non-exclusive basis in the 902–904 MHz and909.75–921.75 MHz sub-bands. Non-multilateration systems andmultilateration systems will share the919.75–921.75 MHz band on a co-equalbasis. Non-multilateration LMS sys-tems may not provide non-vehicular lo-cation services. The maximum antennaheight above ground for non-multilateration LMS systems is 15 me-ters.

(i) Non-multilateration LMS licenseswill be issued on a site-by-site basis,except that municipalities or othergovernmental operatives may filejointly for a non-multilateration li-cense covering a given U.S. Depart-ment of Commerce Bureau of EconomicAnalysis Economic Area (EA). Such anapplication must identify all plannedsites. After receiving the license, thenon-multilateration EA licensee mustnotify the Commission if sites are de-leted or if new sites are added, beforethose sites may be put into operation.


§ 90.355 LMS operations below 512MHz.

Applications requiring not more than25 kHz bandwidth per frequency in the25–50 MHz, 150–170 MHz, and 450–512MHz bands may use either base-mobilefrequencies currently assigned the ap-plicant, or be assigned base-mobile fre-quencies available in the service inwhich eligibility has been established,provided that:

(a) For transmission between vehi-cles and base stations, each frequencyin a single-frequency mode of operationwill provide location data for approxi-mately 200 vehicles, or both frequenciesin a two-frequency mode of operationwill provide location data for approxi-mately 400 vehicles, except that for fre-quencies in the 450–512 MHz band thatare assigned in pairs in accordancewith the allocation plan for the band,the requirement is that location databe provided for approximately 200 vehi-cles for each frequency pair; and ashowing is made that 50 percent of thevehicles will be in operation within thesystem by the end of the second year ofthe initial license term, and 70 percentwill be in operation within the systemby the end of the initial license term;except that if these vehicle loadingstandards will not be met, frequencieswill be assigned only on a secondarynon-interference basis to any author-ized radiotelephony operation.

(b) The minimum separation betweena proposed LMS station and the near-est co-channel base station of anotherlicensee operating a voice system is 75miles (120 km) for a single frequencymode of operation or 35 miles (56 km)for a two-frequency mode of operation.Where the minimum mileage separa-tion cannot be achieved, agreement tothe use of F1D, F2D, G1D, G2D or P0Nemission must be received from all ex-isting co-channel licensees using voiceemissions within the applicable mile-age limits. If there is interference withvoice operations and required agree-ment was not received, or operationwas authorized on a secondary non-in-terference basis, the licensee of theLMS system is responsible for elimi-nating the interference.

§ 90.425 Station identification.Stations licensed under this part

shall transmit identification in accord-ance with the following provisions:

(a) Identification procedure. Except asprovided for in paragraph (d) of thissection, each station or system shall beidentified by the transmission of theassigned call sign during each trans-mission or exchange of transmissions,or once each 15 minutes (30 minutes inthe Public Safety Pool) during periodsof continuous operation. The call signshall be transmitted by voice in theEnglish language or by InternationalMorse Code in accordance with para-graph (b) of this section. If the stationis employing either analog or digitalvoice scrambling, or non-voice emis-sion, transmission of the required iden-tification shall be in the unscrambledmode using A3E, F3E or G3E emission,or International Morse, with all encod-ing disabled. Permissible alternativeidentification procedures are as fol-lows:

(1) A mobile relay stations call signmay be used to identify the associatedcontrol and mobile stations, except inthe Public Safety Pool where the sta-tions operate on frequencies below 450MHz. Alternatively, a base station (in-cluding a mobile relay station) whichis controlled by radio may be identifiedby the transmission of the call sign ofthe station at which communicationsoriginate.

(2) One or more fixed relay stationsmay be identified by the transmissionof the call signs of the stations atwhich the communications originate.

(3) When a mobile station transmitson a different frequency than its asso-ciated base station, the assigned callsign of either the mobile station or thebase station may be transmitted. Fur-ther, a single mobile unit in the licens-ee’s authorized geographic area of oper-

ation may transmit station identifica-tion on behalf of any other operatingmobile units in the fleet.

(4) Use of an identifier other than theassigned call sign. (i) In the Public Safe-ty Pool, mobile units licensed to a gov-ernmental entity and which operate onfrequencies above 30 MHz may use anidentifier which contains, at a mini-mum, the name of the licensee if the li-censee maintains at the station a listof the special identifiers to be used bythe mobile units.

(ii) In the Industrial/Business Pool,licensees may request the Commis-sion’s local Engineer-in-Charge to ap-prove the use of special mobile unitidentifiers in lieu of the assigned callsign. Such requests, however, will notbe granted where it appears that harm-ful interference to international oper-ations may be caused by stations below50 MHz, or by stations operating inareas within 80 km (50 miles) of aninternational boundary, or where it ap-pears that the proposed method ofidentification will not adequately dis-tinguish the mobile units of the appli-cant from the mobile units of other li-censees in the area.

(iii) In the Industrial/Business Pool,railroad licensees (as defined in § 90.7)may identify stations by the name ofthe railroad and the train number, ca-boose number, engine number, or thename of the fixed wayside station. Ifnone of these forms are practicable,any similar name or number may bedesignated by the railroad concernedfor use by its employees in the identi-fication of fixed points or mobile units;Provided, That, a list of such identifiersis maintained by the railroad. An ab-breviated name or the initials of therailroad may be used where such are ingeneral usage. In those areas where itis shown that no difficulty would be en-countered in identifying the trans-mission of a particular station (as, forexample, where stations of one licenseeare located in a yard isolated fromother radio installations), approvalmay be given to a request from the li-censee for permission to omit the sta-tion identification.

(5) Use of identifiers in addition to as-signed call signs. Nothing in this sectionshall be construed as prohibiting the


410

47 CFR Ch. I (10–1–98 Edition)§ 90.425

transmission of station or unit identifi-ers which may be necessary or desir-able for system operation, Provided,That, they are transmitted in additionto the assigned station call sign orother permissible form of identifica-tion.

(b) Use of automatic Morse code identi-fication equipment. Automatically acti-vated equipment may be used to trans-mit station identification in Inter-national Morse Code pursuant to thefollowing conditions:

(1) The signal output of the auto-matic identification equipment shallbe connected to the transmitter at themicrophone input or any other manu-facturer-provided signal input terminaland shall be adjusted to produce 40 per-cent ± 10 percent of the maximum per-missible modulation or deviation level.This adjustment shall be performedwhen all other modulating signals areabsent.

(2) The Morse code transmission rateshall be maintained between 20 and 25words per minute.

(3) The frequency of the keyed tonecomprising the identification signalshall be 1200 ± 800 Hz. A licensee may berequired to change the frequency inorder to prevent interference to the op-erations of another co-channel li-censee.

(4) Should activation of automaticMorse code identification equipmentinterrupt the communications of an-other co-channel licensee, the Commis-sion may require the use of equipmentwhich will delay automatic stationidentification until such co-channelcommunications are completed.

(c) Special provisions for identificationin the Radiolocation Service. (1) Stationsin the Radiolocation Service are notrequired to identify except upon spe-cific instruction from the Commissionor as required by paragraph (c)(2) ofthis section.

(2) Stations in the RadiolocationService operating on frequencies above3400 kHz that employ spread spectrumtechniques shall transmit a two-lettermanufacturer’s designator, authorizedby the Commission on the station au-thorization, at the beginning and end-ing of each transmission and onceevery 15 minutes during periods of con-tinuing operation. The designator shall

be transmitted in International MorseCode at a speed not exceeding 25 wordsper minute, and the spread spectrummode of operation shall be maintainedwhile the designator is being transmit-ted. The identifying signal shall beclearly receivable in the demodulatedaudio of a narrow-band FM receiver.

(d) General exemptions. A station neednot transmit identification if:

(1) It is a mobile station operating onthe transmitting frequency of the asso-ciated base station.

(2) It is a mobile station in the PublicSafety Pool using F1E or G1E emission.

(3) It is transmitting for telemeteringpurposes or for the activation of de-vices which are employed solely as ameans of attracting attention, or forremote control purposes, or which isretransmitting by self-actuatingmeans, a radio signal received from an-other radio station or stations.

(4) It is any type of radiopositioningor radar station authorized in a serviceother than the Radiolocation Service.

(5) It is used solely for automatic ve-hicle monitoring or location.

(6) It is a paging station authorizedin accordance with the provisions of§ 90.20(a)(2)(v).

(7) It is a mobile station employingnon-voice emissions and the associatedbase station identifies on behalf of themobile unit(s).

(8) It is a base or mobile station inthe 220–222 MHz band authorized to op-erate on a nationwide basis in accord-ance with subpart T of this part.

(9) It is a wireless microphone stationoperating in accordance with the provi-sions of § 90.265(b).

(e) Special provisions for stations li-censed under this part that are classi-fied as CMRS providers under part 20 ofthis chapter.

(1) Station identification will not berequired for 929–930 MHz nationwidepaging licensees and MTA-based SMRlicensees. All other CMRS stations willbe required to comply with the stationidentification requirements of para-graphs (a) through (d) of this section.

(2) CMRS stations subject to a sta-tion identification requirement will bepermitted to use a single call sign forcommonly owned facilities that are op-erated as part of a single system. Thecall sign must be transmitted each


411


hour within five minutes of the hour,or upon completion of the first trans-mission after the hour.

(3) CMRS stations granted exclusivechannels may transmit their call signsdigitally. The station licensee mustprovide the Commission with informa-tion sufficient to decode the digitaltransmission to ascertain the trans-mitted call sign.

[43 FR 54791, Nov. 22, 1978]


§ 90.427 Precautions against unauthor-ized operation.

(a) Each transmitter shall be so in-stalled and protected that it is not ac-cessible to or capable of operation bypersons other than those duly author-ized by and under the control of the li-censee. Provisions of this part author-izing certain unlicensed persons to op-erate stations, or authorizing unat-tended operation of stations in certaincircumstances, shall not be construedto change or diminish in any respectthe responsibility of station licenseesto maintain control over the stationslicensed to them (including all trans-mitter units thereof), or for the properfunctioning and operation of those sta-tions and transmitter units in accord-ance with the terms of the licenses ofthose stations.

(b) Except for frequencies used in ac-cordance with § 90.417, no person shallprogram into a transmitter frequenciesfor which the licensee using the trans-mitter is not authorized.

[43 FR 54791, Nov. 22, 1978, as amended at 52FR 47570, Dec. 15, 1987]

§ 90.429 Control point and dispatchpoint requirements.

(a) Control point required. Unless per-mitted to be operated on an unattendedbasis, each station shall be providedwith a control point;

(b) A control point is an operatingposition:

(1) Which must be under the controland supervision of the licensee;

(2) Where a person immediately re-sponsible for the operation of thetransmitter is stationed;

(c) Control point location. The locationof the control point will be specified inthe station license and will be assumedto be the same as that of the transmit-ting equipment unless an applicationfor a different location has been ap-proved by the Commission.

(d) Control point facilities required. Ateach control point, the following facili-ties shall be installed:

(1) A carrier-operated device whichwill provide continuous visual indica-tion when the transmitter is radiating,or, a pilot lamp or meter which willprovide continuous visual indicationwhen the transmitter circuits havebeen placed in a condition to produceradiation. The provisions of this sub-paragraph shall not apply to hand-car-ried transmitters or transmitters in-stalled on motorcycles. The controlpoint for a transmitter utilized to acti-vate another radio station may employa single pilot lamp or meter as an indi-cation of the activation of local and re-mote transmitters.

(2) Facilities which will permit theperson responsible for the operation ofthe transmitter either to disconnectthe dispatch point circuits from thetransmitter or to render the transmit-ter inoperative from any dispatch pointunder his supervision; and

(3) Facilities which will permit theperson responsible for the operation ofthe transmitter to turn the transmit-ter carrier on and off at will.

(e) Dispatch point. A dispatch point isany position from which messages maybe transmitted under the supervision ofthe person at a control point who is re-sponsible for the operation of thetransmitter. Dispatch points may beinstalled without authorization fromthe Commission.

Subpart O—Transmitter Control§ 90.460 Scope.

This subpart sets forth the provisionsrelating to permissible methods oftransmitter control and interconnec-tion (see the definition in § 90.7) ofradio systems authorized under thispart.


§ 90.461 Direct and remote control oftransmitters.

(a) In general. Radio transmittersmay be operated and controlled di-rectly (as when the operating positionfor the transmitter and the transmit-ter being operated are at the same lo-cation), or remotely (as when thetransmitter being operated and the po-sition from which it is being operatedare at different locations).

(b) Control of transmitters at remote lo-cations. Radio transmitters at remotelocations may be operated and con-trolled through the use of wire line orradio links; or through dial-up circuits,


414

47 CFR Ch. I (10–1–98 Edition)§ 90.463

as provided in paragraph (c) of this sec-tion. Such control links or circuitsmay be either those of the licensee orthey may be provided by common car-riers authorized by law to furnish suchservice.

(c) Dial-up circuits. Dial-up circuitsmay be provided by wire line telephonecompanies under appropriate tariffs,and they may be used by licensees forpurposes of transmitter control, pro-vided:

(1) The dial-up circuits serve only tolink licensed transmitter controlpoints and the transmitters being con-trolled.

(2) The dial-up circuits are so de-signed that the transmitters being con-trolled cannot be operated from anyfixed position other than the licensedcontrol points for those transmitters.

(3) Equipment used to provide thetransmitter/dial-up-circuit interface isdesigned to preclude associated mobileunits of the licensee from reaching anypoint(s) served by the wire line tele-phone facilities other than the controlpoint(s) of the station(s) controlled.

(4) Any direct electrical connectionto the telephone network shall complywith applicable tariffs and with part 68of the Commission’s Rules (See§ 90.5(j)).

(5) Interconnection, within the mean-ing of §§ 90.7 and 90.477 through 90.483,may not take place at a control pointwhich connects to its associated trans-mitter(s) through dial-up circuits; normay such dial-up transmitter controlcircuits be used in conjunction with (orshared by) interconnection equipment.

[43 FR 54791, Nov. 22, 1978, as amended at 44FR 67124, Nov. 23, 1979; 60 FR 50123, Sept. 28,1995]

§ 90.463 Transmitter control points.(a) A control operator is required to

be stationed at the operating positionof a transmitter control point. A con-trol operator is any person designatedby the licensee to exercise supervisionand control over the operation and useof the licensee’s facilities. The controloperator may be the licensee; or an em-ployee of the licensee; or the agent ofthe licensee, appointed by the licenseeto act as the control operator; or athird-party contractor, engaged by thelicensee to serve as the control opera-

tor: Provided, however, In no case,through appointment or designation ofany person to serve as control opera-tor, may the licensee delegate any ofthe duties and responsibilities the li-censee may have in his capacity as li-censee.

(b) Each station or licensed system ofcommunication shall normally have acontrol point, or control points, atwhich the control operator or opera-tors are stationed and at or from whichthe licensee may exercise supervisionand control over the authorized facili-ties, as required by the provisions of§ 90.461. Provided, however, Controlpoint requirements may vary from onesystem to another, depending upon thenature of the radio operation; the wayand by whom the facilities are em-ployed; and other factors, as set out inother rule sections under this subpart.

(c) A transmitter control point maybe located at a fixed position in a sys-tem of communication at or fromwhich the control operator exercisessupervision and control over the oper-ation and use of the licensed facilities.Each fixed transmitter control pointshall have equipment and facilities topermit the control operator:

(1) To determine when the transmit-ter or transmitters controlled are ei-ther radiating ‘‘RF’’ energy, or whenthe transmitter circuits have beenplaced in a condition to produce suchradiation. This may be accomplishedeither through the use of a carrier op-erated device which provides a visualindication when the transmitter(s) areradiating or a pilot lamp or meterwhich provides a visual indicationwhen the transmitter circuits havebeen placed in a condition to produceradiation. Further, where a local trans-mitter is used to activate a remotetransmitter or transmitters in the li-censee’s system of communication, asingle pilot lamp or meter may be em-ployed to indicate the activation ofboth the local and the remote trans-mitter(s).

(2) To turn the carrier of the trans-mitter on and off at will, or to closethe system down completely, when cir-cumstances warrant such action.

(d) The licensee’s transmitting facili-ties may be operated from dispatchpoints, the fixed control point shall


415


have equipment to permit the controloperator to either disconnect the dis-patch point circuits from the transmit-ter(s) or to render the transmitter(s)inoperative from any dispatch pointbeing supervised.

(e) Where the system is inter-connected with public communicationfacilities, as provided at §§ 90.477through 90.483, and where those rules sorequire, the fixed control point shall beequipped to permit the control opera-tor:

(1) To monitor co-channel facilitiesof other licensees sharing an assignedchannel or channels with the licenseein the licensee’s area of operation; and,

(2) To terminate any transmission(s)or communication(s) between points inthe public communications system andthe private communications system.

(f) In urban areas, the location offixed transmitter control points will bespecified, ‘‘same as transmitter,’’ un-less the control point is at a street ad-dress which is different from that ofthe transmitter(s) controlled. In ruralareas, the location of fixed controlpoints will be specified, ‘‘same astransmitter,’’ unless the control pointis more than 152.5 m (500 ft) from thetransmitter(s) controlled. In the lattercase, the approximate location of thecontrol point will be specified in dis-tance and direction from the transmit-ter(s) controlled in terms of distanceand geographical quadrant, respec-tively. It would be assumed that the lo-cation of a fixed control point is thesame as the location of the transmit-ter(s) controlled, unless the applicantincludes a request for a different loca-tion described in appropriate terms asindicated herein.

(g) [Reserved](h) Mobile transmitters shall be as-

sumed to be under the immediate con-trol of the mobile operator; provided,however, overall supervision and con-trol of the operation and use of a com-munication system may be the respon-sibility of a fixed control point opera-tor. In general, mobile transmittersshall be equipped to permit the opera-tor to determine when they are radiat-ing ‘‘RF’’ energy or when the transmit-ter circuits have been placed in a con-dition to produce such radiation. Thismay be accomplished either through

the use of a carrier operated device orof a pilot lamp or meter which will pro-vide a visual indication when thetransmitter is radiating or has beenplaced in a condition to produce radi-ation provided, however, that hand-car-ried or pack-carried transmitters andtransmitters installed on motorcyclesneed not be so equipped.

§ 90.465 Control of systems of commu-nication.

(a) Depending on design consider-ations, control of a system of commu-nication may be exercised in varyingways. In single frequency simplex,base/mobile operations, control may beexercised by the control operator atthe fixed control point. In mobile relaysystems, where there is an associatedcontrol point or control station, con-trol may be exercised by the operatorat the control point or control station.In mobile-only systems, control may beexercised by the mobile operator. Incommunication systems involving mul-tiple base stations or fixed relays con-trol of the system may result from acombination of factors and consider-ations, including control by a fixedcontrol point operator at some pointwithin the system of communication orcontrol by the mobile station operatorof the licensee.

(b) In internal systems, as defined at§ 90.7 control may be maintained byconforming the system to the require-ments of §§ 90.471 through 90.475.

(c) In interconnected systems, as de-fined at § 90.7 control may be main-tained by conforming operation andsystem design to that permitted at§§ 90.477 through 90.483.

[43 FR 54791, Nov. 22, 1978, as amended at 54FR 39740, Sept. 28, 1989]

§ 90.467 Dispatch points.

Dispatch points meeting the require-ments of this section need not be spe-cifically authorized; provided, however,that the licensee of any radio stationoperated from a dispatch point orpoints shall assume full responsibility


416

47 CFR Ch. I (10–1–98 Edition)§ 90.469

for the use and operation of the author-ized facilities in compliance with allapplicable provisions of law or rule andshall comply with the policy:

(a) A dispatch point may be linked tothe transmitter(s) being operated byprivate or leased wire line of fixedradio circuits, provided the require-ments of § 90.463 are met.

(b) No telephone position in the pub-lic, switched, telephone network willbe treated as a dispatch point withinthe meaning or intent of this section.

(c) Operation of transmitting facili-ties from dispatch points is permittedonly when the control operator at afixed control point in the system is onduty and at no other time.

§ 90.469 Unattended operation.

(a) Subject to the provisions of§§ 90.243, 90.245, and 90.247, mobile relay,fixed relay, and mobile repeater sta-tions are authorized for unattended op-eration; and the transmitter controlpoint requirements set out at §§ 90.463through 90.465 shall not apply.

(b) Self-activated transmitters maybe authorized for unattended operationwhere they are activated by eitherelectrical or mechanical devices, pro-vided the licensee adopts reasonablemeans to guard against malfunctionsand harmful interference to otherusers.

INTERNAL TRANSMITTER CONTROL

SYSTEMS

§ 90.471 Points of operation in internaltransmitter control systems.

The transmitting facilities of the li-censee may be operated from fixed po-sitions located on premises controlledby the licensee. The fixed position maybe part of a private telephone exchangeor it may be any position in a closed orlimited access communications facilityintended to be used by employees ofthe licensee for internal communica-tions and transmitter control purposes.Operating positions in internal trans-mitter control systems are not synony-mous with dispatch points (See § 90.467)nor with telephone positions which arepart of the public, switched telephonenetwork; and the scheme of regulation

is to be considered and treated as beingdifferent. See §§ 90.485 through 90.489.

[44 FR 67125, Nov. 23, 1979]

§ 90.473 Operation of internal trans-mitter control systems through li-censed fixed control points.

An internal transmitter control sys-tem may be operated under the controland supervision of a control operatorstationed at a fixed control point inthe system. In such a case, the controlpoint must be equipped to permit thecontrol operator to monitor all trafficto and from fixed positions and mobilestations or paging units of the licensee;and the system shall be so designed topermit the control operator to eitherdisconnect any operating position inthe internal system from the transmit-ter control circuit or to close the sys-tem down entirely at will.

[44 FR 67125, Nov. 23, 1979]

§ 90.475 Operation of internal trans-mitter control systems in speciallyequipped systems.

(a) An internal transmitter controlsystem need not be designed to meetthe requirements of § 90.473 if it meetsthe following requirements:

(1) All operating positions must belocated on premises controlled by thelicensee.

(2) An internal transmitter controlsystem may be used in conjunctionwith other approved methods of trans-mitter control and interconnection solong as the internal transmitter con-trol system, itself, is neither accessedfrom telephone positions in the publicswitched telephone network, nor useddial-up circuits in the public switchedtelephone network. Licensees withcomplex communications systems in-volving fixed systems whose base sta-tions are controlled by such systemsmay automatically access these basestations through the microwave oroperational fixed systems from posi-tions in the PSTN, so long as the basestations and mobile units meet the re-quirements of § 90.483 and if a separatecircuit is provided for each mode oftransmitter operation (i.e., conven-tional, dial-up or internal).


417


(3) The system must be designed sothat upon completion of a trans-mission, the base station transmit-ter(s) will close down automaticallywithin 3 seconds.

(4) To guard against malfunctions,the system must also be designed sothat the base station(s) will be deacti-vated by an automatic timing devicewhen a modulated signal is not trans-mitted for a period of three (3) consecu-tive minutes.

(5) The system must include auto-matic monitoring equipment, installedat the base station transmitter site(s),which will prevent the activation ofthe system when signals of other co-channel stations are present.

§ 90.477 Interconnected systems.(a) Applicants for new land stations

to be interconnected with the publicswitched telephone network must indi-cate on their applications (class of sta-tion code) that their stations will be

interconnected. Licensees of land sta-tions that are not interconnected mayinterconnect their stations with thepublic switched telephone networkonly after modifying their license. See§ 90.135. In all cases a detailed descrip-tion of how interconnection is accom-plished must be maintained by licens-ees as part of their station records. See§ 90.433.

(b) In the frequency ranges 806–824MHz, 851–869 MHz, 896–901 MHz, and 935–940 MHz, interconnection with the pub-lic switched telephone network is au-thorized under the following condi-tions:

(1) Interconnected operation is on asecondary basis to dispatch operation.This restriction will not apply totrunked systems or on any channel as-signed exclusively to one licensee.

(2) Interconnection may be accom-plished at any location through a sepa-rate or shared interconnection device.When land stations subject to this partare multiple licensed or shared by au-thorized users, arrangements for tele-phone service must be made with aduly authorized carrier by users, li-censees, or their authorized agents on anon-profit cost sharing basis. Whentelephone service costs are shared, atleast one licensee participating in thecost sharing arrangement must main-tain cost sharing records and the costsmust be distributed at least once ayear. Licensees, users, or their author-ized agents may also make joint use ar-rangements with a duly authorized car-rier and arrange that each licensee oruser pay the carrier directly for the li-censee’s or user’s share of the joint useof the shared telephone service. A re-port of the cost distribution must beplaced in the licensee’s station recordsand made available to participants inthe sharing and the Commission uponrequest. In all cases, arrangementswith the duly authorized carrier mustdisclose the number of licensees andusers and the nature of the use.

(c) Interconnection of facilities inthe Radiolocation Service (subpart F)will not be permitted.

(d) In the frequency ranges below 800MHz, interconnection with the publicswitched telephone network is author-ized under the following conditions:


418

47 CFR Ch. I (10–1–98 Edition)§ 90.477

(1) Interconnected operation is on asecondary basis to dispatch operation.This restriction will not apply totrunked systems or on any channel as-signed exclusively to one licensee.

(2) Interconnection may be accom-plished at any location through a sepa-rate or shared interconnection device.When land stations subject to this partare multiple licensed or shared by au-thorized users, arrangements for tele-phone service must be made with aduly authorized carrier by users, li-censees, or their authorized agents on anon-profit cost sharing basis. Whentelephone service costs are shared, atleast one licensee participating in thecost sharing arrangement must main-tain cost sharing records and the costsmust be distributed at least once ayear. Licensees, users, or their author-ized agents may also make joint use ar-rangements with a duly authorized car-rier and arrange that each licensee oruser pay the carrier directly for the li-censee’s or user’s share of the joint useof the shared telephone service. A re-port of the cost distribution must beplaced in the licensee’s station recordsand made available to participants inthe sharing and the Commission uponrequest. In all cases, arrangementswith the duly authorized carrier mustdisclose the number of licensees andusers and the nature of the use.

(3) For licensees in the Industrial/Business Pool and those licensees whoestablish eligibility pursuant to§ 90.20(a)(2), except for §§ 90.20(a)(2)(i)and 90.20(a)(2)(ii) and medical emer-gency systems in the 450–470 MHz band,interconnection will be permitted onlywhere the base station site or sites pro-posed stations are located 120 km (75mi.) or more from the designated cen-ters of the urbanized areas listedbelow. If these licensees seek to con-nect within 120 km (75 mi.) of the 25cities, they must obtain the consent ofall co-channel licensees located bothwithin 120 km (75 mi.) of the center ofthe city; and within 120 km (75 mi.) ofthe interconnected base station trans-mitter. The consensual agreementsamong the co-channel licensees mustspecifically state the terms agreedupon and a statement must be submit-ted to the Commission indicating that

all co-channel licensees have consentedto the use of interconnection. If a li-censee has agreed to the use of inter-connection on the channel, but laterdecides against the use of interconnec-tion, the licensee may request that theco-channel licensees reconsider the useof interconnection. If the licensee isunable to reach an agreement with co-channel licensees, the licensee may re-quest that the Commission considerthe matter and assign it to anotherchannel. If a new licensee is assigned toa frequency where all the co-channel li-censees have agreed to the use of inter-connection and the new licensee doesnot agree, the new licensee may re-quest that the co-channel licensees re-consider the use of interconnection. Ifthe new licensee can not reach anagreement with co-channel licensees itmay request that the Commission reas-sign it to another channel.

§ 90.483 Permissible methods and re-quirements of interconnecting pri-vate and public systems of commu-nications.

Interconnection may be accom-plished by commercial mobile serviceproviders licensed under this part byany technically feasible means. Inter-connection may be accomplished byprivate mobile service providers eithermanually or automatically under thesupervision and control of a transmit-ter control operator at a fixed positionin the authorized system of commu-nications or it may be accomplishedunder the supervision and control ofmobile operators, and is subject to thefollowing provisions:

(a) Where a system is interconnectedmanually at a fixed control point, thecontrol point operator must maintainthe capability to turn the carrier of thetransmitter off or to de-activate thesystem completely when circumstanceswarrant such action.

(b) When the system is inter-connected automatically it may be su-pervised at the control point or in mo-bile units.

(1) For control point supervision, thefollowing is required:

(i) The control point operator mustmaintain the capability to turn thecarrier of the transmitter off or to de-activate the system completely whencircumstances warrant such action.

(ii) When a frequency is shared bymore than one system, automatic mon-itoring equipment must be installed atthe base station to prevent activationof the transmitter when signals of co-channel stations are present and acti-vation would interfere with commu-nications in progress. Licensees mayoperate without the monitoring equip-ment if they have obtained the consentof all co-channel licensees locatedwithin a 120 km (75 mile) radius of theinterconnected base station transmit-ter. A statement must be submitted to

the Commission indicating that all co-channel licensees have consented to op-erate without the monitoring equip-ment. If a licensee has agreed that theuse of monitoring equipment is notnecessary, but later decides that themonitoring equipment is necessary, thelicensee may request that the co-chan-nel licensees reconsider the use of mon-itoring equipment. If the licensee can-not reach an agreement with co-chan-nel licensees, the licensee may requestthat the Commission consider the mat-ter and assign it to another channel. Ifa new licensee is assigned to a fre-quency where all the co-channel licens-ees have agreed that the use of mon-itoring equipment is not necessary, andthe new licensee does not agree, thenew licensee may request the co-chan-nel licensees to reconsider the use ofmonitoring equipment. If the new li-censee cannot reach an agreement withco-channel licensees, it should requesta new channel from the Commission.Systems on frequencies above 800 MHzare exempt from this requirement.

(2) For mobile unit supervision, thefollowing is required:

(i) When a frequency is shared bymore than one system, automatic mon-itoring equipment must be installed ateach base station to prevent its activa-tion when signals of other co-channelstations are present and activationwould interfere with communicationsin progress. Licensees may operatewithout this equipment if they haveobtained the consent of all co-channellicensees located within a 120 km (75mile) radius of the interconnected basestation transmitter. A statement mustbe submitted to the Commission indi-cating that all co-channel licenseeshave consented to operate without themonitoring equipment. If a licenseehas agreed that the use of monitoringequipment is not necessary, but laterdecides that the monitoring equipmentis necessary, the licensee may requestthat the co-channel licensees recon-sider the use of monitoring equipment.If the licensee cannot reach an agree-ment with co-channel licensees, the li-censee may request that the Commis-sion consider the matter and assign itto another channel. If a new licensee isassigned to a frequency where all theco-channel licensees have agreed that


420

47 CFR Ch. I (10–1–98 Edition)§ 90.483

the use of monitoring equipment is notnecessary, and the new licensee doesnot agree, the new licensee may re-quest the co-channel licensees to re-consider the use of monitoring equip-ment. If the new licensee cannot reachan agreement with co-channel licens-ees, it should request a new channelfrom the Commission. Systems above800 MHz are exempt from this require-ment.

(ii) Initial access from points withinthe public switched telephone networkmust be limited to transmission of a 3-second tone, after which time thetransmitter shall close down. No addi-tional signals may be transmitted untilacknowledgement from a mobile sta-tion of the licensee is received. Licens-ees are exempt from this requirementif they have obtained the consent of allco-channel licensees located within a120 km (75 mile) radius of the inter-connected base station transmitter.However, licensees may choose to settheir own time limitations. A state-ment must be submitted to the Com-mission indicating that all co-channellicensees have consented to operatewithout the monitoring equipment. If alicensee has agreed that the use ofmonitoring equipment is not nec-essary, but later decides that the mon-itoring equipment is necessary, the li-censee may request that the co-channellicensees reconsider the use of mon-itoring equipment. If the licensee can-not reach an agreement with co-chan-nel licensees, the licensee may requestthat the Commission consider the mat-ter and assign it to another channel. Ifa new licensee is assigned to a fre-quency where all the co-channel licens-ees have agreed that the use of mon-itoring equipment is not necessary, andthe new licensee does not agree, thenew licensee may request the co-chan-nel licensees to reconsider the use ofmonitoring equipment. If the new li-censee cannot reach an agreement withco-channel licensees, it should requesta new channel from the Commission.Systems above 800 MHz are exemptfrom this requirement.

(c) In single frequency systems,equipment must be installed at thebase station which will limit any singletransmission from within the publicswitched telephone network to 30 sec-

onds duration and which in turn willactivate the base station receiver tomonitor the frequency for a period ofnot less than three (3) seconds. The mo-bile station must be capable of termi-nating the communications during thethree (3) seconds. Licensees are exemptfrom this requirement if they have ob-tained the consent of all co-channel li-censees located within a 120 km (75mile) radius of the interconnected basestation transmitter. However, licenseesmay choose to set their own time limi-tations. A statement must be submit-ted to the Commission indicating thatall co-channel licensees have consentedto operate without the monitoringequipment. If a licensee has agreedthat the use of monitoring equipmentis not necessary, but later decides thatthe monitoring equipment is necessary,the licensee may request that the co-channel licensees reconsider the use ofmonitoring equipment. If the licenseecannot reach an agreement with co-channel licensees, the licensee may re-quest that the Commission considerthe matter and assign it another chan-nel. If a new licensee is assigned to afrequency where all the co-channel li-censees have agreed that the use ofmonitoring equipment. If the new li-censee cannot reach an agreement withco-channel licensees, it should requesta new channel from the Commission.

(d) A timer must be installed at thebase station transmitter which limitscommunications to three (3) minutes.After three (3) minutes, the systemmust close down, with all circuits be-tween the base station and the publicswitch telephone network discon-nected. This provision does not applyto systems which establish eligibilitypursuant to §§ 90.20(a)(1)(i),90.20(a)(1)(ii), and 90.20(a)(2), except§§ 90.20(a)(2)(i) and 90.20(a)(2)(ii), or whoare Power, Petroleum, or Railroad li-censees (as defined in § 90.7), or to sys-tems above 800 MHz. All systems mustbe equipped with a timer that closesdown the transmitter within threeminutes of the last transmission. Li-censees may operate without these re-quirements if they have obtained theconsent of all co-channel licensees lo-cated within a 120 km (75 mile) radiusof the interconnected base stationtransmitter. However, licensees may


421


choose to set their own time limita-tions. A statement must be submittedto the Commission indicating that allco-channel licensees have consented tooperate without the monitoring equip-ment. If a licensee has agreed that theuse of monitoring equipment is notnecessary, but later decides that themonitoring equipment is necessary, thelicensee may request that the co-chan-nel licensees reconsider the use of mon-itoring equipment. If the licensee can-not reach an agreement with co-chan-nel licensees, the licensee may requestthat the Commission consider the mat-ter and assign it to another channel. Ifa new licensee is assigned to a fre-quency where all the co-channel licens-ees have agreed that the use of mon-itoring equipment is not necessary, andthe new licensee does not agree, thenew licensee may request the co-chan-nel licensees to reconsider the use ofmonitoring equipment. If the new li-censee cannot reach an agreement withco-channel licensees, it should requesta new channel from the Commission.

Subpart P—Paging Operations§ 90.490 One-way paging operations in

the private services.(a) Subject to specific prohibition or

restriction by rule provisions govern-ing the radio service in which a licens-ee’s radio system is authorized, pagingoperations are permitted:

(1) Where the signals and messagesare transmitted by a control operatorof the licensee stationed at a licensedcontrol point in the licensee’s systemof communication.

(2) Where the signals and messagesare transmitted from an operating po-sition within an internal system ofcommunication which meets the testsof §§ 90.471 through 90.475.

(3) Where the signals and messagesare transmitted from a dispatch pointwithin the licensee’s system of commu-nication, as defined as § 90.7.

(b) Systems employing dial-up cir-cuits (§ 90.461(c)) may be used in one-way paging operations, but only where

the paging signals are transmitted asprovided at paragraph (a)(1) of this sec-tion.

(c) Paging may be initiated directlyfrom telephone positions in the publicswitched telephone network. Whenland stations are multiple licensed orotherwise shared by authorized users,arrangements for the telephone servicemust be made with a duly authorizedcarrier by users, licensees, or their au-thorized agents on a non-profit, cost-shared basis. When telephone servicecosts are shared, at least one licenseeparticipating in the cost sharing ar-rangements must maintain cost shar-ing records and the costs must be dis-tributed at least once a year. Licens-ees, users, or their authorized agentsmay also make joint use arrangementswith a duly authorized carrier and ar-range that each licensee or user paythe carrier directly for the licensee’s oruser’s share of the joint use of theshared telephone service. A report ofthe cost distribution must be placed inthe licensee’s station records and madeavailable to participants in the sharingarrangement and the Commission uponrequest. In all cases, arrangementswith the duly authorized carrier mustdisclose the number of licensees andusers and the nature of the use.

(2) Certain channels in the 821–824/866–869 MHz band are also available toeligible applicants in the Public Safety

Category in areas within 110 kilo-meters (68.4 miles) of the U.S./Mexicoborder. These channels will be assignedaccording to the policies defined in theReport and Order of Gen. Docket No. 87–112 (See § 90.16). The following channelsare available only for mutual aid pur-poses as defined in Gen. Docket No. 87–112: channels 601, 639, 677, 715, and 753.Certain channels in the 896–901/935–940MHz band are also available in areaswithin 110 kilometers (68.4 miles) of theU.S./Mexico border. The specific chan-nels that are available for licensing inthe bands 821–824/866–869 and 896–901/935–940 MHz within 110 kilometers (68.4miles) of the Mexico border are listedin tables 1B, 2B, 3B, and 4B and are sub-ject to Effective Radiated Power (ERP)and Antenna Height limitations as in-dicated in table 1C. In addition, allchannels designated for use withinMexico in the 821–824/866–869 MHz and896–901/935–940 MHz bands are availablefor assignment to U.S. stations within110 kilometers (68.4 miles) of the Mex-ico border if the maximum power fluxdensity (pfd) of the station’s transmit-ted signal at any point at or beyondthe border does not exceed ¥107 dB(W/m2). The spreading loss must be cal-culated using the free space formulataking into account any antenna dis-crimination in the direction of the bor-der. Authorizations for stations usingchannels allotted to Mexico on a pri-mary basis will be secondary to Mexi-can operations and conditioned to re-quire that licensees take immediateaction to eliminate any harmful inter-ference resulting from the station’stransmitted signal exceeding ¥107dB(W/m2).

(ii) For frequencies in the 808.2625–811.2375/853.2625–856.2375 MHz and815.7625–818.7375/860.7625–863.7375 MHzbands, for stations to be located in thegeographical area in Region 3 enclosedby the meridian 81° W longitude, thearc of a circle of 100 km radius centeredat the intersection of 81° W longitudeand the northern shore of Lake Erieand drawn clockwise from the south-erly intersection with 81° W longitudeto intersect the United States-Canadaborder, and the United States-Canadaborder.

(5) Applicants requesting authoriza-tions in the frequency bands in the geo-graphical areas listed below shall sub-mit documentation indicating compli-ance with the following protection cri-teria to the indicated Canadian tele-vision station. Protection to Canadiantelevision assignments and allotmentsis based on the field strength of aninterfering mobile radio signal at theTV station’s calculated Grade B con-tour (64 dBu) not exceeding the TVfield strength by more than 20 dB (i.e.,84 dBu). The field strength of the TVassignment or allotment is calculatedusing the R6602 [F(50,50)] propagationcurves and any land mobile base sta-tion interfering signal is calculatedusing the R6602 [F(50,10)] propagationcurves at a receiving effective antennaheight of 9.1 meters (30 feet). Where thecalculated field strength of the TV as-signment or allotment exceeds theGrade B contour value of 64 dBu at theCanada/U.S.A. border, the land mobileradio signal may not exceed the actualcalculated TV field strength at the bor-der by more than 20 dB.

§ 90.621 Selection and assignment offrequencies.

(a) Applicants for frequencies in thePublic Safety, Industrial/Land Trans-portation, and Business Categoriesmust specify on the application the fre-quencies on which the proposed systemwill operate pursuant to a rec-ommendation by the applicable fre-quency coordinator. Applicants for fre-quencies in the SMR Category must re-quest specific frequencies by includingin their applications the frequenciesrequested.

(1) For trunked systems, the assign-ment of frequencies will be made in ac-cordance with applicable loading cri-teria and in accordance with the fol-lowing:

(i) Channels will be chosen and as-signed in accordance with §§ 90.615,90.617, or 90.619.

(ii) A mobile station is authorized totransmit on any frequency assigned toits associated base station.

(iii) There are no limitations on thenumber of frequencies that may betrunked. Authorizations for non-SMRstations may be granted for up to 20trunked frequency pairs at a time inaccordance with the frequencies listedin §§ 90.615, 90.617, and 90.619.

(2) For conventional systems the as-signment of frequencies will be made inaccordance with applicable loading cri-teria. Accordingly, depending upon thenumber of mobile units to be served, anapplicant may either be required toshare a channel, or, if an applicantshows a sufficient number of mobileunits to warrant the assignment of oneor more channels for its exclusive use,it may be licensed to use such channelor channels on an unshared basis in thearea of operation specified in its appli-cation.

(i) Channels will be chosen and as-signed in accordance with §§ 90.615,90.617, or 90.619.

(ii) A mobile station is authorized totransmit on any frequency assigned toits associated base station.

(b) Stations authorized on fre-quencies listed in this subpart, exceptfor those stations authorized pursuantto paragraph (g) of this section and EA-based and MTA-based SMR systems,will be afforded protection solely onthe basis of fixed distance separationcriteria. For Channel Blocks A,through V, as set forth in § 90.917(d),the separation between co-channel sys-tems will be a minimum of 113 km (70mi) with one exception. For incumbentlicensees in Channel Blocks D throughV, that have received the consent of allaffected parties to utilize an 18 dBµV/msignal strength interference contour(see § 90.693), the separation betweenco-channel systems will be a minimumof 173 km (107 mi). The following excep-tions to these separations shall apply:

(1) Except as indicated in paragraph(b)(4) of this section, no station inChannel Blocks A through V shall beless than 169 km (105 mi) distant froma co-channel station that has beengranted channel exclusivity and au-thorized 1 kW ERP on any of the fol-lowing mountaintop sites: SantiagoPeak, Sierra Peak, Mount Lukens,Mount Wilson (California). Except asindicated in paragraph (b)(4) of thissection, no incumbent licensee inChannel Blocks D through V that havereceived the consent of all affected par-

ties to utilize an 18 dBµV/m signalstrength interference contour shall beless than 229 km (142 mi) distant froma co-channel station that has beengranted channel exclusivity and au-thorized 1 kW ERP on any of the fol-lowing mountaintop sites: SantiagoPeak, Sierra Peak, Mount Lukens,Mount Wilson (California).

(2) The separation between co-chan-nel stations that have been granted ex-clusivity and that are located at highsites in California north of 35° N Lati-tude and west of 118° W Longitude shallbe determined as follows:

(i) Required co-channel separationsbetween common antenna sites aregiven by table 1. A channel group as-signed to a station on a site listed inthe vertical column may not be re-as-signed to a station on a site listed inthe horizontal column if there is an‘‘X’’ in the box created by the intersec-tion of the vertical and horizontallines. The geographic coordinates list-ed in the table represent an average foreach particular site; all locations with-in 1.6 km (1 mi) of the coordinates willbe considered to be at that site.

(ii) Required co-channel separationsinvolving antenna sites not listed intable 1 shall be determined by Commis-sion staff on a case by case basis. Theinterference potential of proposed as-signments will be evaluated consider-ing parameters such as antenna height,effective radiated power, terrain irreg-ularities, and market conditions.

The following table indicatesseparations assignable to such co-chan-nel stations for various transmitterpower and antenna height combina-tions. The minimum separation per-mitted is 88 km (55 mi). Applicants willprovide the Commission with a state-ment that the application is submittedfor consideration under the table, a listof all co-channel stations within 113km (70 mi), and the DHAATs and ERPsfor these stations and the applicant’sproposed station. Applicants seeking tobe licensed for stations located at dis-tances less than those prescribed in thetable are required to secure a waiverand must submit with the application,in addition to the above, an inter-ference analysis, based upon any of thegenerally-accepted terrain-based prop-agation models, that shows that co-channel stations would receive thesame or greater interference protectionthan provided in the table. Requestsfor separations less than 88 km (55 mi)must also include an analysis of inter-ference potential from mobile trans-mitters to existing co-channel base sta-tion receivers. Applicants seeking awaiver must submit with their applica-

tion a certificate of service indicatingthat concurrent with the submission ofthe application to the Commission or acoordinator, all co-channel licenseeswithin the applicable area were servedwith a copy of the application and allattachments thereto. Licensees thusserved may file an opposition to the ap-plication within 30 days from the datethe application is filed with the Com-mission.

(i) The directional height of the an-tenna above average terrain (DHAAT)is calculated from the average of theantenna heights above average terrainfrom 3 to 16 km (2 to 10 mi) from theproposed site along a radial extendingin the direction of the existing stationand the radials 15 degrees to either sideof that radial.

(ii) Except for the sites listed in para-graphs (b)(1), (b)(2), and (b)(3) of thissection, additional co-channel distanceseparation must be afforded to an ex-isting station from an applicant wish-ing to locate a station less than 113 km(70 mi) from a co-channel station,where either the applicant’s or the ex-isting station is located at sites withDHAATs of 458 m (1500 ft) and above.The separation between short-spacedco-channel stations shall be deter-mined as follows:

(A) Calculate the DHAAT in each di-rection between every existing co-channel station with 113 km (70 mi) andthe proposed station.

(B) In the table, locate the approxi-mate ERP and DHAAT values for theproposed and existing stations.

(C) When DHAAT values are greaterthan 458 m (1500 ft), use the requiredseparation for 305 m (1000 ft) and add 1.6km (1 mi) for every 30.5 km (100 ft), orincrement thereof, of DHAAT above 458m (1500 ft) to the distance indicated inthe table. If both the proposed existingstations have DHAATs of 458 m (1500 ft)or more, the additional distance is sep-arately determined for each stationand the combined distance is added tothe distance obtained from the table.Protection to existing stations will beafforded only up to 113 km (70 mi).

1 Separations for stations on Santiago Peak, Sierra Peak, Mount Lukens, and Mount Wilson (CA) and the locations in the Stateof Washington listed in paragraph (b)(3) of this section are 56 km (35 mi) greater than those listed in the table above. In theevent of conflict between this table and the table of additional California high elevation sites shown in paragraph (b)(2) of thissection, the latter will apply.

2 Distances shown are derived from the R–6602 curves and are based upon a non-overlap of the 22 dBu (F50,10) interferencecontour of the proposed station with the 40 dBu (F50,50) contour of the existing station(s). No consideration is given to the 40dBu service contour of the proposed station and the 22 dBu contour of the existing station(s). The minimum separation of sta-tions will be 88 km (55 mi).

3 All existing stations are assumed to operate with 1000 watts ERP. When the ERP and/or DHAAT of a proposed station or theDHAAT of an existing station is not indicated in the table, the next higher value(s) must be used.

(5) The separation between co-chan-nel systems may be less than the sepa-rations defined above if an applicantsubmits with its application letters ofconcurrence indicating that the appli-cant and each co-channel licenseewithin the specified separation agree toaccept any interference resulting fromthe reduced separation between theirsystems. Each letter from a co-channellicensee must certify that the systemof the concurring licensee is con-structed and fully operational. The ap-plicant must also submit with its ap-plication a certificate of service indi-cating that all concurring co-channel

licensees have been served with an ac-tual copy of the application.

(6) A station located closer than thedistances provided in this section to aco-channel station that was authorizedas short-spaced under paragraph (b)(4)of this section shall be permitted tomodify its facilities as long as the sta-tion does not extend its 22 dBu contourbeyond its maximum 22 dBu contour(i.e., the 22 dBu contour calculatedusing the station’s maximum powerand antenna height at its original loca-tion) in the direction of the short-spaced station.

§ 90.629 Extended implementation pe-riod.

Applicants requesting frequencies foreither trunked or conventional oper-ations may be authorized a period of upto five (5) years for constructing andplacing a system in operation in ac-cordance with the following:

(a) The applicant must justify an ex-tended implementation period. The jus-tification must describe the proposedsystem, state the amount of time nec-essary to construct and place the sys-tem in operation, identify the numberof base stations to be constructed andplaced in operation during each year ofthe extended construction period, andshow that:

(1) The proposed system will requirelonger than eight months (if a conven-tional system) or one year (if a trunkedsystem) to construct and place in oper-ation because of its purpose, size, orcomplexity; or

(2) The proposed system is to be partof a coordinated or integrated wide-area system which will require morethan eight months (if a conventionalsystem) or one year (if a trunked sys-tem) to plan, approve, fund, purchase,construct, and place in operation; or


458

47 CFR Ch. I (10–1–98 Edition)§ 90.631

(3) The applicant is required by lawto follow a multi-year cycle for plan-ning, approval, funding, and purchasingthe proposed system.

(b) Where an applicant is required bylaw to follow a multi-year cycle forplanning, approval, funding and pur-chasing a proposed system, the appli-cant must indicate whether funding ap-proval has been obtained and if not,when such funding approval is ex-pected.

(c) Authorizations under this sectionare conditioned upon the licensee con-structing and placing its system in op-eration within the authorized imple-mentation period and in accordancewith an approved implementation planof up to five years. Licensees must cer-tify annually that they are in compli-ance with their yearly station con-struction commitments, but may re-quest amendment to these commit-ments at the time they file their an-nual certification. If the Commissionapproves the requested amendments toa licensee’s implementation commit-ments, the licensee’s extended imple-mentation authority will remain in ef-fect. If, however, the Commission con-cludes, at this or any other time, thata licensee has failed to meet its com-mitments, the Commission will termi-nate authority for the extended imple-mentation period. When the Commis-sion terminates an extended implemen-tation authority, the affected licenseewill be given six months from the dateof termination to complete systemconstruction. At the end of any licens-ee’s extended implementation period,authorizations for all stations not con-structed and placed in operation will becancelled. Trunked systems granted anextended implementation period mustcomply with the channel loading re-quirements of section 90.631(b). Conven-tional channels not loaded to 70 mobileunits may be subject to shared use bythe addition of other licensees.

(d) Applicants eligible in the Indus-trial/Land Transportation Category re-questing authorizations under this sec-tion may request frequencies in theBusiness Category only if the applica-tion contains a statement that no fre-quencies in the Industrial/Land Trans-portation Category are available for as-signment in their geographic area.

(e) As of March 18, 1996, SpecializedMobile Radio systems are not eligiblefor extended implementation periodsunder this section. Additionally, all 800MHz SMR licensees that are operatingunder extended implementation au-thority as of March 18, 1996 must, byMay 16, 1996, demonstrate that continu-ing to allow them to have an extendedperiod of time to construct their facili-ties is warranted and furthers the pub-lic interest. If a licensee’s extended im-plementation authority showing is ap-proved by the Bureau, such licenseewill be afforded an extended implemen-tation of two years or the remainder ofits current extended implementationperiod, whichever is shorter. Upon thetermination of this period, the author-izations for those facilities that remainunconstructed will terminate auto-matically. If a licensee with a currentextended implementation period failsto submit the showing mentionedabove within the designated timeframeor submits an insufficient or incom-plete showing, such licensee will havesix months from the last day on whichit could timely file such a showing orfrom the disapproval of its request toconstruct the remaining facilities cov-ered under its implementation plan toconstruct any unconstructed facilitiesfor which it is authorized. The author-izations for those facilities remainingunconstructed after this six-month pe-riod will terminate automatically.

§ 90.631 Trunked systems loading, con-struction and authorization re-quirements.

(a) Non-SMR trunked systems will beauthorized on the basis of a loading cri-teria of one hundred (100) mobile sta-tions per channel. For purposes of de-termining compliance with trunkedsystem loading requirements underthis subpart, the term ‘‘mobile sta-tion’’ includes vehicular and portablemobile units and control stations.

(b) Each applicant for a non-SMRtrunked system must certify that aminimum of seventy (70) mobiles foreach channel authorized will be placedinto operation within five (5) years ofthe initial license grant. Except forSMR systems licensed in the 806–821/


459


851–866 MHz band and as indicated inparagraph (i) of this section, if at theend of five (5) years a trunked systemis not loaded to the prescribed levelsand all channels in the licensee’s cat-egory are assigned in the system’s geo-graphic area, authorizations fortrunked channels not loaded to seventy(70) mobile stations cancels automati-cally at a rate that allows the licenseeto retain one channel for every onehundred (100) mobiles loaded, plus oneadditional channel. If a trunked systemhas channels from more than one cat-egory, Spectrum Block D frequenciesin the 800 MHz SMR service (formerlyGeneral Category) channels are thefirst channels considered to cancelautomatically. All non-SMR licenseesinitially authorized before June 1, 1993,that are within their original licenseterm, or SMR licensees that are withinthe term of a two-year authorizationgranted in accordance with paragraph(i) of this section, are subject to thiscondition. A licensee that has author-ized channels cancelled due to failureto meet the above loading require-ments will not be authorized additionalchannels to expand that same systemfor a period of six (6) months from thedate of cancellation.

(c) Except for SMR applicants and asprovided in paragraph (d) of this sec-tion, an applicant seeking to expand atrunked system by requesting addi-tional channels from the Commission,or through intercategory sharing, orthrough an assignment, must have aloading level of seventy (70) mobilesper channel on the existing systemthat is the subject of the expansion re-quest.

(d) In rural areas, a licensee of atrunked system may request to in-crease its system capacity by five morechannels than it has constructed with-out meeting the loading requirementsspecified in paragraphs (b) and (c) ofthis section. A rural area is defined forpurposes of this section as being be-yond a 100-mile radius of the des-ignated centers of the following urban-ized areas, as well as those areas thathave a waiting list. (Rural areas maybe different for 800 and 900 MHz chan-nels since the Commission maintainsseparate waiting lists for these fre-quency bands.) The identified urban-

ized areas are: New York, NY; Los An-geles, CA; Chicago, IL; Philadelphia,PA: San Francisco, CA; Detroit, MI;Boston, MA; Houston, TX; Washington,DC; Dallas-Fort Worth, TX; Miami, FL;Cleveland, OH; St. Louis, MO; Atlanta,GA; Pittsburgh, PA; Baltimore, MD;Minneapolis-St. Paul, MN; Seattle,WA; San Diego, CA; and Tampa-St. Pe-tersburg, FL. The coordinates for thecenters of these areas are those ref-erenced in § 90.635, except that the co-ordinates for Tampa-St. Petersburg arelatitude 28°00′00′′ N, longitude 82°27′00′′W. Where waiting lists determinewhether an area is rural, the des-ignated centers of those areas will beidentified on the actual waiting listsreleased by the Commission. If a wait-ing list is later established in a ruralarea, licensees who have acquired addi-tional channels pursuant to this para-graph will be subject to the automaticcancellation provisions in paragraph(b) of this section at the end of oneyear from the date the area first ap-pears on a Commission waiting list, orat the end of their license term, which-ever is longer.

(e) Except as provided in § 90.629, li-censees of trunked facilities must com-plete construction within one year.

(f) If a station is not placed in perma-nent operation, in accordance with thetechnical parameters of the station au-thorization, within one year, except asprovided in § 90.629, its license cancelsautomatically and must be returned tothe Commission. For purposes of thissection, a base station is not consid-ered to be placed in operation unless atleast two associated mobile stations, orone control station and one mobile sta-tion, are also placed in operation. AnSMR licensee with facilities that havediscontinued operations for 90 continu-ous days after the effective date of thisrule is presumed to have permanentlydiscontinued operations, unless the li-censee notifies the FCC otherwise priorto the end of the 90 day period and pro-vides a date on which operation will re-sume, which date must not be in excessof 30 additional days.

(g) Wide area systems may be author-ized to persons eligible for licensingunder subparts B or C of this part uponan appropriate showing of need. Re-mote or satellite stations of wide area


460

47 CFR Ch. I (10–1–98 Edition)§ 90.633

systems in the Public Safety, SpecialEmergency, Telephone Maintenance,and Power Radio Services may be au-thorized on a primary basis if such sta-tions are the first to be authorized intheir area of operation on the fre-quency or group of frequencies. Remoteor satellite stations of wide area sys-tems in all other services will be au-thorized only on a secondary, non-in-terference basis to cochannel licensees.To determine system loading, the totalnumber of mobile units and controlstations operating in the wide-area sys-tem shall be counted with respect tothe total number of base station fre-quencies assigned to the system.

(h) Regional, statewide, or ribbonconfiguration systems may be author-ized to persons eligible for licensingunder subparts B or C of this part uponan appropriate showing of need. In aribbon, regional or statewide system, amobile station will be counted forchannel loading purposes only for thebase station facility in the geographicarea in which it primarily operates. Ifthis cannot be determined, it will becounted fractionally over the numberof base station facilities with which itcommunicates regularly.

(i) For SMRS category trunked sys-tems licensed in the 896–901/935–940 MHzband (other than MTA-licensed sys-tems), if at the end of the initial five-year license term the licensee of such atrunked system has not satisfied theloading requirements of paragraph (b)of this section, the licensee requestingrenewal of its license will be granted arenewal for only a two-year period. Re-gardless of the date of grant of the two-year renewal, the licensee will be re-quired to comply fully with the mini-mum requirements set forth in para-graph (b) of this section at the end ofthe two-year renewal term. As an ex-ception to this requirement, if the li-censee obtains the MTA license cover-ing its assigned spectrum in accord-ance with §§ 90.661 through 90.671, theseloading requirements will no longer be

applicable and the coverage require-ments of § 90.665 will govern.

§ 90.633 Conventional systems loadingrequirements.

(a) Non-SMR conventional systems ofcommunication will be authorized onthe basis of a minimum loading cri-teria of seventy (70) mobile stations foreach channel authorized.

(b) A channel will not be assigned toadditional licensees when it is loadedto 70 mobile stations. Where a licenseedoes not load a channel to 70 mobilesthe channel will be available for as-signment to other licensees. All au-thorizations for conventional systemsare issued subject to this potentialchannel sharing condition.

(c) Except as provided in § 90.629 li-censees of conventional systems mustplace their authorized facilities in op-eration not later than eight monthsafter the date of grant of the licensefor the system.

(d) If a station is not placed in oper-ation in eight months, except as pro-vided in § 90.629, its license cancelsautomatically and must be returned tothe Commission. For purposes of thissection, a base station is not consid-ered to be placed in operation unless atleast one associated mobile station isalso placed in operation.

(e) A non-SMR licensee may apply foradditional frequency pairs if its au-thorized conventional channel(s) isloaded to seventy (70) mobiles. Applica-tions may be considered for additionalchannels in areas where spectrum isstill available and not applied for, evenif the already authorized channel(s) isnot loaded to 70 mobile units, upon anappropriate demonstration of need.

(f) Wide area systems may be author-ized to persons eligible for licensingunder subparts B or C of this part upon

an appropriate showing of need. Forloading purposes, if the total number ofmobile stations justifies the total num-ber of authorized based frequencies in agiven area, the system will be con-strued to be loaded.

(g) Regional, statewide, or ribbonconfiguration systems may be author-ized to persons eligible for licensingunder subparts B or C of this part uponan appropriate showing of need. In aribbon, regional or statewide system, amobile station will be counted forchannel loading purposes only for thebase station facility in the geographicarea in which it primarily operates. Ifthis cannot be determined, it will becounted fractionally over the numberof base station facilities with which itcommunicates regularly.

(a) Except for control stations, oper-ational fixed operations will not be au-thorized in the 806–824 MHz, 851–869MHz, 896–901 MHz, or 935–940 MHzbands. This does not preclude second-ary fixed tone signaling and alarm op-erations authorized in § 90.235 or inparagraph (c) of this section.

(b) Control stations associated withone or more mobile relay stations willbe authorized only on the assigned fre-quency of the associated mobile sta-tion. Use of a mobile service frequencyby a control station of a mobile relaysystem is subject to the condition thatharmful interference shall not becaused to stations of licensees author-ized to use the frequency for mobileservice communications.

(c) Trunked and conventional sys-tems that have exclusive-use status intheir respective geographic areas mayconduct fixed ancillary signaling anddata transmissions subject to the fol-lowing requirements:

(1) All operations must be on a sec-ondary, non-interference basis to theprimary mobile operation of any otherlicensee.

(2) The output power at the remotesite must not exceed 30 watts.

(3) Any fixed transmitters will notcount toward meeting the mobile load-ing requirements nor be considered in

whole or in part as a justification forauthorizing additional frequencies inthe licensee’s mobile system.

(4) Automatic means must be pro-vided to deactivate the remote trans-mitter in the event the carrier remainson for a period in excess of three min-utes.

(5) Operational fixed stations author-ized pursuant to the provisions of para-graphs (c) and (d) of this section are ex-empt from the requirements of §§ 90.425and 90.429.

(d) Conventional systems that do nothave exclusive-use status in their re-spective geographic areas may conductfixed ancillary signaling and datatransmissions only in accordance withall the provisions of § 90.235.

(e) An SMRS licensee or a licenseewho has been authorized a channel(s)on an exclusive basis, may use the sys-tem for the transmission of any base/mobile message, page or signal per-mitted in the service in which the par-ticipants are eligible.

(f) Where the channel(s) is assignedto an SMRS licensee or exclusively toa single licensee, or where all users ofa system agree, more than a singleemission may be utilized within the au-thorized bandwidth. In such cases, thefrequency stability requirements of§ 90.213 shall not apply, but out-of-bandemission limits of § 90.209 shall be met.

(g) Up to five (5) contiguous 806–821/851–866 band channels as listed in§§ 90.615, 90.617, and 90.619 may be au-thorized after justification for systemsrequiring more than the normal singlechannel bandwidth. If necessary, li-censees may trade channels amongstthemselves in order to obtain contig-uous frequencies. Notification of suchproposed exchanges shall be made tothe appropriate frequency coordina-tor(s) and to the Commission for ap-proval.

(h) Up to 10 contiguous 896–901/935–940MHz band channels as listed in § 90.617may be combined for systems requiringmore than the normal single channelbandwidth. If necessary, licensees maytrade channels amongst themselves inorder to obtain contiguous frequencies.Notification of such proposed ex-changes shall be made to the appro-priate frequency coordinator(s) and tothe Commission for approval.

§ 90.647 Station identification.

(a) Conventional systems of commu-nication shall be identified in accord-

ance with existing regulations govern-ing such matters.

(b) Trunked systems of communica-tion, except as noted in paragraph (c)of this section, shall be identifiedthrough the use of an automatic devicewhich transmits the call sign of thebase station facility at 30 minute inter-vals. Such station identification shallbe made on the lowest frequency in thebase station trunk group assigned thelicensee. Should this frequency be inuse at the time station identification isrequired, such identification may bemade at the termination of the com-munication in progress on this fre-quency. Identification may be made byvoice or International Morse Code.When the call sign is transmitted inInternational Morse Code, it must beat a rate of between 15 to 20 words perminute and by means of tone modula-tion of the transmitter, the tone fre-quency being between 800 and 1000hertz.

(c) Stations operating in either the806–824/851–869 MHz or 896–901/935–940MHz bands that are licensed on an ex-clusive basis, and normally employ dig-ital signals for the transmission ofdata, text, control codes, or digitizedvoice may also be identified by digitaltransmission of the call sign. A li-censee that identifies its station in thismanner must provide the Commission,upon its request, information sufficientto decode the digital transmission andascertain the call sign transmitted.

§ 90.699 Transition of the upper 200channels in the 800 MHz band to EAlicensing.

In order to facilitate provision ofservice throughout an EA, an EA li-censee may relocate incumbent licens-ees in its EA by providing ‘‘comparablefacilities’’ on other frequencies in the800 MHz band. Such relocation is sub-ject to the following provisions:

(a) EA licensees may negotiate withincumbent licensees as defined in§ 90.693 operating on frequencies inSpectrum Blocks A, B, and C for thepurpose of agreeing to terms underwhich the incumbents would relocatetheir operations to other frequencies inthe 800 MHz band, or alternatively,would accept a sharing arrangementwith the EA licensee that may resultin an otherwise impermissible level ofinterference to the incumbent licens-ee’s operations. EA licensees may alsonegotiate agreements for relocation of


471


the incumbents’ facilities within Spec-trum Blocks A, B or C in which all in-terested parties agree to the relocationof the incumbent’s facilities elsewherewithin these bands. ‘‘All interestedparties’’ includes the incumbent li-censee, the EA licensee requesting andpaying for the relocation, and any EAlicensee of the spectrum to which theincumbent’s facilities are to be relo-cated.

(b) The relocation mechanism con-sists of two phases that must be com-pleted before an EA licensee may pro-ceed to request the involuntary reloca-tion of an incumbent licensee.

(1) Voluntary negotiations. There is aone year voluntary period during whichan EA licensee and an incumbent maynegotiate any mutually agreeable relo-cation agreement. The Commissionwill announce the commencement ofthe first phase voluntary period byPublic Notice. EA licensees must no-tify incumbents operating on fre-quencies included in their spectrumblock of their intention to relocatesuch incumbents within 90 days of therelease of the Public Notice that com-mences the voluntary negotiation pe-riod. Failure on the part of the EA li-censee to notify the incumbent li-censee during this 90 period of its in-tention to relocate the incumbent willresult in the forfeiture of the EA li-censee’s right to request involuntaryrelocation of the incumbent at anytime in the future.

(2) Mandatory negotiations. If noagreement is reached by the end of thevoluntary period, a one-year manda-tory negotiation period will begin dur-ing which both the EA licensee and theincumbent must negotiate in ‘‘goodfaith.’’ Failure on the part of the EA li-censee to negotiate in good faith dur-ing this mandatory period will resultin the forfeiture of the EA licensee’sright to request involuntary relocationof the incumbent at any time in the fu-ture.

(c) Involuntary relocation procedures.If no agreement is reached during ei-ther the voluntary or mandatory nego-tiating periods, the EA licensee mayrequest involuntary relocation of theincumbent’s system. In such a situa-tion, the EA licensee must:

(1) Guarantee payment of relocationcosts, including all engineering, equip-ment, site and FCC fees, as well as anylegitimate and prudent transaction ex-penses incurred by the incumbent li-censee that are directly attributable toan involuntary relocation, subject to acap of two percent of the hard costs in-volved. Hard costs are defined as theactual costs associated with providinga replacement system, such as equip-ment and engineering expenses. EA li-censees are not required to pay incum-bent licensees for internal resourcesdevoted to the relocation process. EAlicensees are not required to pay fortransaction costs incurred by incum-bent licensees during the voluntary ormandatory periods once the involun-tary period is initiated, or for fees thatcannot be legitimately tied to the pro-vision of comparable facilities;

(2) Complete all activities necessaryfor implementing the replacement fa-cilities, including engineering and costanalysis of the relocation procedureand, if radio facilities are used, identi-fying and obtaining, on the incum-bents’ behalf, new frequencies and fre-quency coordination; and

(3) Build the replacement system andtest it for comparability with the ex-isting 800 MHz system.

(d) Comparable facilities. The replace-ment system provided to an incumbentduring an involuntary relocation mustbe at least equivalent to the existing800 MHz system with respect to the fol-lowing four factors:

(1) System. System is defined func-tionally from the end user’s point ofview (i.e., a system is comprised of basestation facilities that operate on an in-tegrated basis to provide service to acommon end user, and all mobile unitsassociated with those base stations). Asystem may include multiple-licensedfacilities that share a common switchor are otherwise operated as a unitarysystem, provided that the end user hasthe ability to access all such facilities.A system may cover more than one EAif its existing geographic coverage ex-tends beyond the EA borders.

(2) Capacity. To meet the comparablefacilities requirement, an EA licenseemust relocate the incumbent to facili-ties that provide equivalent channelcapacity. We define channel capacity


472

47 CFR Ch. I (10–1–98 Edition)§ 90.699

as the same number of channels withthe same bandwidth that is currentlyavailable to the end user. For example,if an incumbent’s system consists offive 50 kHz (two 25 kHz paired fre-quencies) channels, the replacementsystem must also have five 50 kHzchannels. If a different channel con-figuration is used, it must have thesame overall capacity as the originalconfiguration. Comparable channel ca-pacity requires equivalent signalingcapability, baud rate, and access time.In addition, the geographic coverage ofthe channels must be coextensive withthat of the original system.

(3) Quality of service. Comparable fa-cilities must provide the same qualityof service as the facilities being re-placed. Quality of service is defined tomean that the end user enjoys thesame level of interference protectionon the new system as on the old sys-tem. In addition, where voice service isprovided, the voice quality on the newsystem must be equal to the currentsystem. Finally, reliability of serviceis considered to be integral to definingquality of service. Reliability is the de-gree to which information is trans-ferred accurately within the system.Reliability is a function of equipmentfailures (e.g., transmitters, feed lines,antennas, receivers, battery back-uppower, etc.) and the availability of thefrequency channel due to propagationcharacteristics (e.g., frequency, terrain,atmospheric conditions, radio-fre-quency noise, etc.) For digital data sys-tems, this will be measured by the per-cent of time the bit error rate exceedsthe desired value. For analog or digitalvoice transmissions, this will be meas-ured by the percent of time that audiosignal quality meets an establishedthreshold. If analog voice system is re-placed with a digital voice system theresulting frequency response, harmonicdistortion, signal-to-noise ratio, andreliability will be considered.

(4) Operating costs. Operating costsare those costs that affect the deliveryof services to the end user. If the EA li-censee provides facilities that entailhigher operating cost than the incum-bent’s previous system, and the cost in-crease is a direct result of the reloca-tion, the EA licensee must compensatethe incumbent for the difference. Costs

associated with the relocation processcan fall into several categories. First,the incumbent must be compensatedfor any increased recurring costs asso-ciated with the replacement facilitates(e.g., additional rental payments, in-creased utility fees). Second, increasedmaintenance costs must be taken intoconsideration when determiningwhether operating costs are com-parable. For example, maintenancecosts associated with analog systemsmay be higher than the costs of digitalequipment because manufacturers areproducing mostly digital equipmentand analog replacement parts can bedifficult to find. An EA licensee’s obli-gation to pay increased operating costswill end five years after relocation hasoccurred.

(e) If an EA licensee cannot providecomparable facilities to an incumbentlicensee as defined in this section, theincumbent licensee may continue tooperate its system on a primary basisin accordance with the provisions ofthis rule part.

(f) Cost-sharing plan for 800 MHz SMREA licensees. EA licensees are requiredto relocate the existing 800 MHz SMRlicensee in these bands if interferenceto the existing incumbent operationswould occur. All EA licensees who ben-efit from the spectrum clearing byother EA licensees must contribute, ona pro rata basis to such relocationcosts. EA licensees may satisfy this re-quirement by entering into privatecost-sharing agreements or agreeing toterms other than those specified in thissection. However, EA licensees are re-quired to reimburse other EA licenseesthat incur relocation costs and are notparties to the alternative agreement asdefined in this section.

(1) Pro rata formula. EA licensees whobenefit from the relocation of the in-cumbent must share the relocationcosts on a pro rata basis. For purposesof determining whether an EA licenseebenefits from the relocation of an in-cumbent, benefitted will be defined asany EA licensee that:

(i) Notifies incumbents operating onfrequencies included in their spectrumblock of their intention to relocatesuch incumbents within 90 days of the


473


release of the Public Notice that com-mences the voluntary negotiation pe-riod; or

(ii) Fails to notify incumbents oper-ating on frequencies included in theirspectrum block of their intention to re-locate such incumbents within 90 daysof the release of the Public Notice thatcommences the voluntary negotiationperiod, but subsequently decides to usethe frequencies included in their spec-trum block. EA licensees who do notparticipate in the relocation processwill be prohibited from invoking man-datory negotiations or any of the pro-visions of the Commission’s mandatoryrelocation guidelines. EA licensees whodo not provide notice to the incum-bent, but subsequently decide to usethe frequencies in their EA will be re-quired to reimburse, outside of theCommission’s mandatory relocationguidelines, those EA licensees whohave established a reimbursementright pursuant to paragraph (f)(3) ofthis section.

(2) Triggering a reimbursement obliga-tion. An EA licensees reimbursementobligation is triggered by:

(i) Notification (i.e., files a copy ofthe relocation notice and proof of theincumbent’s receipt of the notice tothe Commission within ten days of re-ceipt), to the incumbent within 90 daysof the release of the Public Notice com-mencing the voluntary negotiation pe-riod of its intention to relocate the in-cumbent; or

(ii) An EA licensee who does not pro-vide notification within 90 days of therelease of the Public Notice commenc-ing the voluntary negotiation period,but subsequently decides to use thechannels that were relocated by otherEA licensees.

(3) Triggering a reimbursement right. Inorder for the EA licensee to trigger areimbursement right, the EA licenseemust notify (i.e., files a copy of the re-location notice and proof of the incum-bent’s receipt of the notice to the Com-mission within ten days of receipt), theincumbent of its intention to relocatethe incumbent within 90 days of the re-lease of the Public Notice commencingthe voluntary negotiation period, andsubsequently negotiate and sign a relo-cation agreement with the incumbent.An EA licensee who relocates a channel

outside of its licensed EA (i.e., one thatis in another frequency block or out-side of its market area), is entitled topro rata reimbursement from non-noti-fying EA licensees who subsequentlyexercise their right to the channelsbased on the following formula:

Ci TcChj

TCh= ×

Ci equals the amount of reimbursementTc equals the actual cost of relocating the

incumbentTCh equals the total number of channels

that are being relocatedChj equals the number of channels that

each respective EA licensee will benefitfrom

(4) Payment issues. EA licensees whobenefit from the relocation of the in-cumbent will be required to submittheir pro rata share of the relocationexpense to EA licensees who have trig-gered a reimbursement right and haveincurred relocation costs as follows:

(i) For an EA licensee who, within 90days of the release of the Public Noticeannouncing the commencement of thevoluntary negotiation period, providesnotice of its intention to relocate theincumbent, but does not participate orincur relocation costs in the relocationprocess, will be required to reimbursethose EA licensees who have triggereda reimbursement right and have in-curred relocation costs during the relo-cation process, its pro rata share whenthe channels of the incumbent havebeen cleared (i.e., the incumbent hasbeen fully relocated and the channelsare free and clear).

(ii) For an EA licensee who does not,within 90 days of the release of thePublic Notice announcing the com-mencement of the voluntary negotia-tion period, provide notice to the in-cumbent of its intention to relocateand does not incur relocation costsduring the relocation process, but sub-sequently decides to use the channelsin its EA, will be required to submit itspro rata share payment to those EA li-censees who have triggered a reim-bursement right and have incurred re-location costs during the relocationprocess prior to commencing testing ofits system.

(5) Sunset of reimbursement rights. EAlicensees who do not trigger a reim-bursement obligation as set forth inparagraph (f)(2) of this section, shallnot be required to reimburse EA licens-ees who have triggered a reimburse-ment right as set forth in paragraph(f)(3) of this section ten (10) years afterthe voluntary negotiation period be-gins for EA licensees (i.e., ten (10) yearsafter the Commission releases the Pub-lic Notice commencing the voluntarynegotiation period).

(6) Resolution of disputes that ariseduring relocation. Disputes arising outof the costs of relocation, such as dis-putes over the amount of reimburse-ment required, will be encouraged touse expedited ADR procedures. ADRprocedures provide several alternativemethods such as binding arbitration,mediation, or other ADR techniques.

(7) Administration of the cost-sharingplan. We will allow for an industry sup-ported, not-for-profit clearinghouse tobe established for purposes of admin-istering the cost-sharing plan adoptedfor the 800 MHz SMR relocation proce-dures.

§ 90.743 Renewal expectancy.

(a) All licensees seeking renewal oftheir authorizations at the end of theirlicense term must file a renewal appli-cation in accordance with the provi-sions of § 90.149. Licensees must dem-onstrate, in their application, that:

(1) They have provided ‘‘substantial’’service during their past license term.‘‘Substantial’’ service is defined in thisrule as service that is sound, favorable,and substantially above a level of me-diocre service that just might mini-mally warrant renewal; and

(2) They have substantially compliedwith applicable FCC rules, policies, andthe Communications Act of 1934, asamended.

(b) In order to establish its right to arenewal expectancy, a renewal appli-cant must submit a showing explainingwhy it should receive a renewal expect-ancy. At a minimum, this showingmust include:

(1) A description of its current serv-ice in terms of geographic coverage andpopulation served;

(2) For an EA, Regional, or nation-wide licensee, an explanation of itsrecord of expansion, including a time-table of the construction of new sta-tions to meet changes in demand forservice;

(3) A description of its investments inits system;

(4) Copies of all FCC orders findingthe licensee to have violated the Com-munications Act or any FCC rule orpolicy; and

(5) A list of any pending proceedingsthat relate to any matter described inthis paragraph.

(c) Phase I non-nationwide licenseeshave license terms of 5 years, andtherefore must meet these require-ments 5 years from the date of initialauthorization in order to receive a re-newal expectancy. Phase I nationwidelicensees and all Phase II licenseeshave license terms of 10 years, andtherefore must meet these require-ments 10 years from the date of initial

authorization in order to receive a re-newal expectancy.

[62 FR 15997, Apr. 3, 1997]

§ 90.745 Phase I licensee service areas.

(a) A Phase I licensee’s service areashall be defined by the predicted 38 dBuservice contour of its authorized basestation or fixed station transmittingon frequencies in the 220–221 MHz bandat its initially authorized location orat the location authorized in accord-ance with §§ 90.751, 90.753, 90.755 and90.757 if the licensee has sought modi-fication of its license to relocate itsinitially authorized base station. ThePhase I licensee’s predicted 38 dBuservice contour is calculated using theF(50,50) field strength chart for Chan-nels 7–13 in § 73.699 (Fig. 10) of thischapter, with a 9 dB correction factorfor antenna height differential, and isbased on the authorized effective radi-ated power (ERP) and antenna height-above-average-terrain of the licensee’sbase station or fixed station. Phase I li-censees are permitted to add, remove,or modify transmitter sites withintheir existing service area withoutprior notification to the Commission solong as their predicted 38 dBu servicecontour is not expanded. The incum-bent licensee must, however, notify theCommission within 30 days of the com-pletion of any changes in technical pa-rameters or additional stations con-structed through a minor modificationof its license. Such notification mustbe made by submitting the appropriateFCC form and must include the appro-priate filing fee, if any. These minormodification applications are not sub-ject to public notice and petition todeny requirements or mutually exclu-sive applications.

(b) Phase I licensees holding author-izations for service areas that are con-tiguous and overlapping may exchangethese authorizations for a single li-cense, authorizing operations through-out the contiguous and overlappingservice areas. Phase I licensees exercis-ing this license exchange option mustsubmit specific information for each oftheir external base station sites.

[63 FR 32591, June 12, 1998]

§ 90.751 Minor modifications of PhaseI, non-nationwide licenses.

Phase I non-nationwide licensees willbe given an opportunity to seek modi-fication of their license to relocatetheir initially authorized base station,i.e., locate their base station at a siteother than its initially authorized loca-tion. The conditions under which modi-fications will be granted and the proce-dures for applying for license modifica-tions are described in §§ 90.753, 90.755,and 90.757. For CMRS licensees, thesemodifications will be treated as minormodifications in accordance with§ 90.164.

[62 FR 15998, Apr. 3, 1997]

§ 90.753 Conditions of license modifica-tion.

(a) Except as provided in paragraphs(b), and (c) of this section, a Phase Inon nationwide licensee may modifyits authorization to relocate its au-thorized base station up to one-half thedistance over 120 km toward any co-channel licensee’s initially authorizedbase station, to a maximum distance of8 km.

(b) A Phase I non-nationwide licenseewith an authorized base station locatedoutside a Designated Filing Area (DFA)(see Public Notice, DA 86–173, 52 FR1302 (January 12, 1987)) may modify itsauthorization to relocate its author-ized base station up to one-half the dis-tance over 120 km toward any co-chan-nel licensee’s initially authorized basestation, to a maximum distance of 25km, so long as the base station is relo-cated no more than 8 km inside of anyDFA (i.e., no more than 8 km from thenearest DFA boundary line).

(c) A Phase I non-nationwide licenseethat has been granted Special Tem-porary Authority (STA) to operate atan alternative base station locationmay modify its authorization to seekpermanent authorization at that loca-tion, regardless of whether locating thestation at the STA site is in strict con-formance with the provisions of para-graphs (a) and (b) of this section, if thelicensee certifies that such a modifica-tion is in conformance with §§ 90.723and 90.729 and:


489


(1) It has constructed its base stationand has placed it in operation, or com-menced service, at the STA site on orbefore January 26, 1996; or

(2) It has taken delivery of its basestation transceiver on or before Janu-ary 26, 1996.

(d) The application of a Phase I non-nationwide licensee proposing a basestation modification resulting in lessthan 120 km separation from a co-chan-nel licensee’s initially authorized basestation will be accepted by the Com-mission only with the consent of thatco-channel licensee, as evidenced in aletter submitted concurrently with thelicensee’s application.

(e) The application of a Phase I non-nationwide licensee proposing a basestation modification resulting in atleast a 120 km separation from each co-channel licensee’s initially authorizedbase station but more than one-halfthe distance over 120 km toward anyco-channel licensee’s initially author-ized base station will be accepted bythe Commission only with the consentof that co-channel licensee, as evi-denced in a letter submitted concur-rently with the licensee’s application.

[61 FR 3845, Feb. 2, 1996]

§ 90.755 Procedures for license modi-fication.

(a) A Phase I non-nationwide licenseeseeking modification of its authoriza-tion to relocate its authorized base sta-tion in accordance with the provisionsof § 90.753 must file the following on orbefore May 1, 1996:

(1) Form 600 requesting license modi-fication, and providing all applicableinformation;

(2) Certification that the location ofits proposed base station is in conform-ance with the provisions of § 90.753, or,as provided in § 90.753(d), a letter evi-dencing consent of a co-channel li-censee that the licensee may be au-thorized less than 120 km from the co-channel licensee;

(3) If applicable, the required certifi-cation by a licensee with a SpecialTemporary Authority, in accordancewith § 90.753(c);

(4) If applicable, certification thatthe licensee has constructed its basestation and placed it in operation, orcommenced service, at its initially au-

thorized location on or before March11, 1996.

(b) A licensee seeking modification ofits authorization to relocate its basestation in accordance with the provi-sions of § 90.753, should file, on or beforeMarch 11, 1996, either a modificationapplication, as provided in paragraph(a) of this section, or a letter certifyingto the Commission its intent to file anapplication to modify its authorizationto relocate its base station. For a li-censee that has not constructed its au-thorized base station and placed it inoperation, or commenced service, byMarch 11, 1996, this filing will serve toextend the licensee’s construction re-quirement in accordance with the pro-visions of § 90.757.

[61 FR 3845, Feb. 2, 1996]

§ 90.757 Construction requirements.

(a) Except as provided in paragraph(b) of this section, a Phase I non-na-tionwide licensee that is granted modi-fication of its authorization to relocateits base station must construct its basestation and place it in operation, orcommence service, on all authorizedchannels on or before August 15, 1996,or within 12 months of initial grantdate, whichever is later. The authoriza-tion of a licensee that does not con-struct its base station and place it inoperation, or commence service, bythis date, cancels automatically andmust be returned to the Commission.

(b) A Phase I non-nationwide licenseewith a base station authorized at a lo-cation north of Line A must constructits base station and place it in oper-ation, or commence service, on all au-thorized channels within 12 months ofinitial grant date, or within 12 monthsof the date of the release of the termsof an agreement between the UnitedStates and Canadian governments onthe sharing of 220–222 MHz spectrumbetween the two countries, whicheveris later. The authorization of a licenseethat does not construct its base stationand place it in operation, or commenceservice, by this date, cancels automati-cally and must be returned to the Com-mission.

The Commission will employ a simul-taneous multiple round auction designwhen choosing from among mutuallyexclusive initial applications to pro-vide 900 MHz SMR service, unless oth-erwise specified by the Wireless Tele-communications Bureau before theauction.

§ 90.803 Competitive bidding mecha-nisms.

(a) Sequencing. The Wireless Tele-communications Bureau will establishand may vary the sequence in which900 MHz SMR licenses will be auc-tioned.

(b) Grouping. All 900 MHz SMR li-censes for each of the MTAs will beauctioned simultaneously, unless theWireless Telecommunications Bureau

announces, by Public Notice prior tothe auction, an alternative auctionscheme.

(c) Minimum bid increments. The Wire-less Telecommunications Bureau will,by announcement before or during anauction, require minimum bid incre-ments in dollar or percentage terms.

(d) Stopping rules. The Wireless Tele-communications Bureau will establishstopping rules before or during mul-tiple round auctions in order to termi-nate an auction within a reasonabletime.

(e) Activity rules. The Wireless Tele-communications Bureau will establishactivity rules which require a mini-mum amount of bidding activity. Inthe event that the Commission estab-lishes an activity rule in connectionwith a simultaneous multiple roundauction, each bidder will be entitled torequest and will be automaticallygranted a certain number of waivers ofsuch rule during the auction.

§ 90.804 Aggregation of 900 MHz SMRlicenses.

The Commission will license each 10-channel block in the 900 MHz SMRspectrum separately. Applicants mayaggregate across spectrum blocks with-in the limitation specified in § 20.6(b) ofthis chapter.

§ 90.805 Withdrawal, default and dis-qualification payments.

(a) During the course of an auctionconducted pursuant to § 90.802, theWireless Telecommunications Bureauwill impose payments on bidders whowithdraw high bids during the courseof an auction, who default on paymentsdue after an auction closes, or who aredisqualified.

(b) Bid withdrawal prior to close ofauction. A bidder who withdraws ahigh bid during the course of an auc-tion will be subject to a payment equalto the difference between the amountbid and the amount of the winning bidthe next time the license is offered bythe Commission. No withdrawal pay-ment would be assessed if the subse-quent winning bid exceeds the with-drawn bid. This payment amount will


493


be deducted from any upfront pay-ments or down payments that the with-drawing bidder has deposited with theCommission.

(c) Default or disqualification afterclose of auction. See § 1.2104 (g)(2) of thischapter.

§ 90.806 Bidding application (FCCForm 175 and 175–S Short-form).

All applicants to participate in com-petitive bidding for 900 MHz SMR li-censes must submit applications onFCC Forms 175 and 175–S pursuant tothe provisions of § 1.2105 of this chap-ter. The Wireless TelecommunicationsBureau will issue a Public Notice an-nouncing the availability of 900 MHzSMR licenses and, in the event thatmutually exclusive applications arefiled, the date of the auction for thoselicenses. This Public Notice also willspecify the date on or before which ap-plicants intending to participate in a900 MHz SMR auction must file theirapplications in order to be eligible forthat auction, and it will contain infor-mation necessary for completion of theapplication as well as other importantinformation such as the materialswhich must accompany the Forms, anyfiling fee that must accompany the ap-plication or any upfront payment thatwill need to be submitted, and the loca-tion where the application must befiled. In addition to identifying its sta-tus as a small business or rural tele-phone company, each applicant mustindicate whether it is a minority-owned entity, as defined in § 90.814(g)and/or a women-owned entity.

§ 90.807 Submission of upfront pay-ments and down payments.

(a) Each bidder in the 900 MHz SMRauction will be required to submit anupfront payment of $0.02 per MHz perpop, for the maximum number of li-censes (in terms of MHz-pops) on whichit intends to bid pursuant to § 1.2106 ofthis chapter and procedures specifiedby Public Notice.

(b) Each winning bidder in the 900MHz SMR auction shall make a downpayment to the Commission in anamount sufficient to bring its total de-posits up to 20 percent of its winning

bid within five business days after theauction closes, and the remaining bal-ance due on the license shall be paidwithin five business days after PublicNotice announcing that the Commis-sion is prepared to award the license.The grant of the application requiredby § 90.808 is conditional upon receipt offull payment, except for small busi-nesses that are winning bidders, whichare governed by § 90.811. The Commis-sion generally will grant the licensewithin ten (10) business days after thereceipt of the remaining balance dueon the license.

§ 90.808 Long-form applications.

Each winning bidder will be requiredto submit a long-form application onFCC Form 600 within ten (10) businessdays after being notified by Public No-tice that it is the winning bidder. Ap-plications on FCC Form 600 shall besubmitted pursuant to the proceduresset forth in 90.119 and any associatedPublic Notices. Only auction winners(and rural telephone companies and in-cumbent 900 MHz SMR licensees seek-ing partitioned licenses pursuant toagreements with auction winners under§ 90.813) will be eligible to file applica-tions on FCC Form 600 for initial 900MHz SMR licenses in the event of mu-tual exclusivity between applicants fil-ing Form 175.

§ 90.809 License grant, denial, default,and disqualification.

(a) A bidder who withdraws its bidsubsequent to the close of bidding, de-faults on a payment due, or is disquali-fied, will be subject to the paymentsspecified in § 90.805 or § 1.2109 of thischapter, as applicable.

§ 90.810 Bidding credits for small busi-nesses.

(a) A winning bidder that qualifies asa small business or a consortium ofsmall businesses, (as defined in§ 90.814(b)(1)(i) may use a bidding creditof 15 percent to lower the cost of itswinning bid on any of the blocks iden-tified in § 90.617(d), table 4B. A winning


494

47 CFR Ch. I (10–1–98 Edition)§ 90.811

bidder that qualifies as a small busi-ness or a consortium of small busi-nesses, (as defined in § 90.814(b)(1)(ii)may use a bidding credit of 10 percentto lower the cost of its winning bid onany of the blocks identified in§ 90.617(d), table 4B.

(b) Unjust Enrichment. (1) A smallbusiness seeking transfer or assign-ment of a license to an entity that isnot a small business under the defini-tions in § 90.814(b)(1) will be required toreimburse the government for theamount of the bidding credit, plus in-terest at the rate imposed for install-ment financing at the time the licensewas awarded, before transfer will bepermitted. The amount of this pay-ment will be reduced over time as fol-lows: a transfer in the first two yearsof the license term will result in a for-feiture of 100 percent of the value ofthe bidding credit: in year three of thelicense term the payment will be 75percent; in year four the payment willbe 50 percent and in year five the pay-ment will be 25 percent, after whichthere will be no assessment. If a smallbusiness as defined in § 90.814(b)(1)(i)seeks to transfer or assign a license toa small business as defined in§ 90.814(b)(1)(ii), the value of the biddingcredit to be repaid is five percent, thedifference between the 10 and 15 per-cent bidding credits. The five percentdifference will be subject to the per-centage reductions over time specifiedabove. These payments must be paidback to the U.S. Treasury as a condi-tion of approval of the assignment ortransfer.

(2) If a small business that utilizes abidding credit under this section seeksto assign or transfer control of its li-cense to a small business meeting theeligibility standards for lower biddingcredits or seeks to make any otherchange in ownership that would resultin the licensee qualifying for a lowerbidding credit under this section, thelicensee must seek Commission ap-proval and reimburse the governmentfor the difference between the amountof the bidding credit obtained by the li-censee and the bidding credit for whichthe assignee, transferee or licensee iseligible under this section as a condi-tion of the approval of such assign-

ment, transfer or other ownershipchange.

§ 90.811 Reduced down payment for li-censes won by small businesses.

Each winning bidder that qualifies asa small business shall make a downpayment equal to ten percent of itswinning bid (less applicable biddingcredits); a winning bidder shall bringits total amount on deposit with theCommission (including upfront pay-ment) to five percent of its net winningbid within five (5) business days afterthe auction closes, and the remainderof the down payment (five percent)shall be paid within five (5) businessdays following Public Notice that theCommission is prepared to award thelicense. The Commission generally willgrant the license within ten (10) busi-ness days after receipt of the remain-der of the down payment.

§ 90.812 Installment payments for li-censes won by small businesses.

(a) Installment payments. See§ 1.2110(f)(4) of this chapter.

(b) Unjust enrichment. See § 1.2111(c) ofthis chapter.

[63 FR 2349, Jan. 15, 1998]


(a) Eligibility. Parties seeking ap-proval for partitioning anddisaggregation shall request an author-ization for partial assignment of a li-cense pursuant to § 90.153(c).

(b) Technical standards—(1) Partition-ing. In the case of partitioning, re-quests for authorization for partial as-signment of a license must include, asattachments, a description of the parti-tioned service area and a calculation ofthe population of the partitioned serv-ice area and the licensed geographicservice area. The partitioned servicearea shall be defined by coordinatepoints at every 3 degrees along the par-titioned service area unless an FCCrecognized service area is utilized (i.e.,Major Trading Area, Basic TradingArea, Metropolitan Service Area, RuralService Area or Economic Area) orcounty lines are followed. The geo-graphic coordinates must be specifiedin degrees, minutes, and seconds to the


495


nearest second of latitude and lon-gitude and must be based upon the 1927North American Datum (NAD27). Ap-plicants may supply geographical co-ordinates based on 1983 North Amer-ican Datum (NAD83) in addition tothose required (NAD27). In the casewhere an FCC recognized service areaor county lines are utilized, applicantsneed only list the specific area(s)(through use of FCC designations orcounty names) that constitute the par-titioned area.

(2) Disaggregation. Spectrum may bedisaggregated in any amount.

(3) Combined partitioning anddisaggregation. The Commission willconsider requests for partial assign-ment of licenses that propose combina-tions of partitioning anddisaggregation.

(c) Unjust enrichment—(1) Installmentpayments. Licensees that qualifiedunder § 90.812 to pay the net auctionprice for their licenses in installmentpayments that partition their licensesor disaggregate their spectrum to enti-ties not meeting the eligibility stand-ards for installment payments, will besubject to the provisions concerningunjust enrichment as set forth in§ 90.812(b).

(2) Bidding credits. Licensees thatqualified under § 90.810 to use a biddingcredit at auction that partition theirlicenses or disaggregate their spectrumto entities not meeting the eligibilitystandards for such a bidding credit,will be subject to the provisions con-cerning unjust enrichment as set forthin § 90.810(b).

(3) Apportioning unjust enrichmentpayments. Unjust enrichment paymentsfor partitioned license areas shall becalculated based upon the ratio of thepopulation of the partitioned licensearea to the overall population of the li-cense area and by utilizing the most re-cent census data. Unjust enrichmentpayments for disaggregated spectrumshall be calculated based upon theratio of the amount of spectrumdisaggregated to the amount of spec-trum held by the licensee.

(d) Installment payments—(1) Appor-tioning the balance on installment pay-ment plans. When a winning bidderelects to pay for its license through aninstallment payment plan pursuant to

§ 90.812, and partitions its licensed areaor disaggregates spectrum to anotherparty, the outstanding balance owed bythe licensee on its installment pay-ment plan (including accrued and un-paid interest) shall be apportioned be-tween the licensee and partitionee ordisaggregatee. Both parties will be re-sponsible for paying their propor-tionate share of the outstanding bal-ance to the U.S. Treasury. In the caseof partitioning, the balance shall be ap-portioned based upon the ratio of thepopulation of the partitioned area tothe population of the entire original li-cense area calculated based upon themost recent census data. In the case ofdisaggregation, the balance shall be ap-portioned based upon the ratio of theamount of spectrum disaggregated tothe amount of spectrum allocated tothe licensed area.

(2) Parties not qualified for installmentpayment plans. (i) When a winning bid-der elects to pay for its license throughan installment payment plan pursuantto § 90.812, and partitions its license ordisaggregates spectrum to anotherparty that would not qualify for an in-stallment payment plan or elects notto pay for its share of the licensethrough installment payments, theoutstanding balance owed by the li-censee (including accrued and unpaidinterest) shall be apportioned accord-ing to paragraph (d)(1) of this section.

(ii) The partitionee or disaggregateeshall, as a condition of the approval ofthe partial assignment application, payits entire pro rata amount within 30days of Public Notice conditionallygranting the partial assignment appli-cation. Failure to meet this conditionwill result in a rescission of the grantof the partial assignment application.

(iii) The licensee shall be permittedto continue to pay its pro rata share ofthe outstanding balance and shall re-ceive new financing documents (prom-issory note, security agreement) with arevised payment obligation, based onthe remaining amount of time on theoriginal installment payment schedule.These financing documents will replacethe licensee’s existing financing docu-ments which shall be marked ‘‘super-seded’’ and returned to the licensee


496

47 CFR Ch. I (10–1–98 Edition)§ 90.813

upon receipt of the new financing docu-ments. The original interest rate, es-tablished pursuant to § 1.2110(e)(3)(i) ofthis chapter at the time of the grant ofthe initial license in the market, shallcontinue to be applied to the licensee’sportion of the remaining governmentobligation. We will require, as a furthercondition to approval of the partial as-signment application, that the licenseeexecute and return to the U.S. Treas-ury the new financing documents with-in 30 days of the Public Notice condi-tionally granting the partial assign-ment application. Failure to meet thiscondition will result in the automaticcancellation of the grant of the partialassignment application.

(iv) A default on the licensee’s pay-ment obligation will only affect the li-censee’s portion of the market.

(3) Parties qualified for installment pay-ment plans. (i) Where both parties to apartitioning or disaggregation agree-ment qualify for installment payments,the partitionee or disaggregatee will bepermitted to make installment pay-ments on its portion of the remaininggovernment obligation, as calculatedaccording to paragraph (d)(1) of thissection.

(ii) Each party will be required, as acondition to approval of the partial as-signment application, to execute sepa-rate financing documents (promissorynote, security agreement) agreeing topay their pro rata portion of the bal-ance due (including accrued and unpaidinterest) based upon the installmentpayment terms for which they qualifyunder the rules. The financing docu-ments must be returned to the U.S.Treasury within thirty (30) days of thePublic Notice conditionally grantingthe partial assignment application.Failure by either party to meet thiscondition will result in the automaticcancellation of the grant of the partialassignment application. The interestrate, established pursuant to§ 1.2110(e)(3)(i) of this chapter at thetime of the grant of the initial licensein the market, shall continue to be ap-plied to both parties’ portion of thebalance due. Each party will receive alicense for their portion of the parti-tioned market or disaggregated spec-trum.

(iii) A default on an obligation willonly affect that portion of the marketarea held by the defaulting party.

(iv) Partitionees and disaggregateesthat qualify for installment paymentplans may elect to pay some of theirpro rata portion of the balance due in alump sum payment to the U.S. Treas-ury and to pay the remaining portionof the balance due pursuant to an in-stallment payment plan.

(e) License term. The license term fora partitioned license area and fordisaggregated spectrum shall be the re-mainder of the original licensee’s li-cense term as provided for in § 90.665(a).

(f) Construction requirements—(1) Re-quirements for partitioning. Parties seek-ing authority to partition must meetone of the following construction re-quirements:

(i) The partitionee may certify thatit will satisfy the applicable construc-tion requirements set forth in § 90.665for the partitioned license area; or

(ii) The original licensee may certifythat it has or will meet the construc-tion requirements set forth in § 90.665for the entire market. In that case, thepartitionee must only meet the re-quirements for renewal of its licensefor the partitioned license area.

(iii) Applications requesting partialassignments of license for partitioningmust include a certification by eachgeographic area 800 MHz SMR licensesin the lower 230 channels will be award-ed to small entities, as that term is de-fined by the SBA.

(iv) Partitionees must submit sup-porting documents showing compliancewith the respective construction re-quirements within the appropriatetime frames set forth in § 90.665.

(v) Failure by any partitionee tomeet its respective performance re-quirements will result in the auto-matic cancellation of the partitionedor disaggregated license without fur-ther Commission action.

(2) Requirements for disaggregation.Parties seeking authority todisaggregate must submit with theirpartial assignment application a cer-tification signed by both parties stat-ing which of the parties will be respon-sible for meeting the construction re-quirements for the market as set forthin § 90.665. Parties may agree to share


497


responsibility for meeting the con-struction requirements. Parties thataccept responsibility for meeting theconstruction requirements and laterfail to do so will be subject to licenseforfeiture without further Commissionaction.

[62 FR 41219, July 31, 1997]

§ 90.814 Definitions.(a) Scope. The definitions in this sec-

tion apply to §§ 90.810 through 90.813,unless otherwise specified in those sec-tions.

(b) Small business: Consortium of smallbusiness:

(1) A small business is an entity thateither:

(i) together with its affiliates, per-sons or entities that hold attributableinterests in such entity, and their af-filiates, has average gross revenuesthat are not more than $3 million forthe preceding three years; or

(ii) together with its affiliates, per-sons or entities that hold attributableinterests in such entity, and their af-filiates, has average gross revenuesthat are not more than $15 million forthe preceding three years.

(2) For purposes of determiningwhether an entity meets either the $3million or $15 million average annualgross revenues size standard set forthin paragraph (b)(1) of this section, thegross revenues of the entity, its affili-ates, persons or entities holding inter-ests in the entity and their affiliatesshall be considered on a cumulativebasis and aggregated, subject to the ex-ceptions set forth in § 90.814(g).

(3) A small business consortium is aconglomerate organization formed as ajoint venture between or among mutu-ally-independent business firms, eachof which individually satisfies eitherdefinition of a small business in para-graphs (b)(1) and (b)(2) of this section.In a consortium of small businesses,each individual member must establishits eligibility as a small business, asdefined in this section.

(c) Rural telephone company. A ruraltelephone company is a local exchangecarrier having 100,000 or fewer accesslines, including all affiliates.

(d) Gross revenues. For applicationsfiled after December 31, 1994, gross reve-nues shall be evidenced by audited fi-

nancial statements for the precedingrelevant number of calendar or fiscalyears. If an entity was not in existencefor all or part of the relevant period,gross revenues shall be evidenced bythe audited financial statements of theentity’s predecessor-in-interest or, ifthere is no identifiable predecessor-in-interest, unaudited financial state-ments certified by the applicant as ac-curate.

(e) Businesses owned by members of mi-nority groups and/or women. A businessowned by members of minority groupsand/or women in which minorities and/or women who are U.S. citizens controlthe applicant, have at least 50.1 percentequity ownership and, in the case of acorporate applicant, a 50.1 percent vot-ing interest. For applicants that arepartnerships, every general partner ei-ther must be a minority and/or woman(or minorities and/or women) who areU.S. citizens and who individually ortogether own at least 50.1 percent ofthe partnership equity, or an entitythat is 100 percent owned and con-trolled by minorities and/or womenwho are U.S. citizens. The interests ofminorities and women are to be cal-culated on a fully-diluted basis; agree-ments such as stock options and con-vertible debentures shall be consideredto have a present effect on the power tocontrol an entity and shall be treatedas if the rights thereunder alreadyhave been fully exercised. However,upon a demonstration that options orconversion rights held by non-control-ling principals will not deprive the mi-nority and female principals of a sub-stantial financial stake in the ventureor impair their rights to control thedesignated entity, a designated entitymay seek a waiver of the requirementthat the equity of the minority and fe-male principals must be calculated ona fully-diluted basis.

(f) Members of minority groups. Mem-bers of minority groups includes Blacks,Hispanics, American Indians, AlaskanNatives, Asians, and Pacific Islanders.

(g) Attributable interests. Partnershipand other ownership interests and anystock interest amounting to 20 percentor more of the equity, or outstandingstock, or outstanding voting stock of alicensee or applicant will be attrib-utable.


498

47 CFR Ch. I (10–1–98 Edition)§ 90.814

(1) Multiplier. Ownership intereststhat are held indirectly by any partythrough one or more intervening cor-porations will be determined by succes-sive multiplication of the ownershippercentages for each link in the verti-cal ownership chain and application ofthe relevant attribution benchmark tothe resulting product, except that ifthe ownership percentage for an inter-est in any line in the chain exceeds 50percent or represents actual control, itshall be treated as if it were a 100 per-cent interest.

(2) [Reserved](h) Affiliate. (1) Basis for affiliation. An

individual or entity is an affiliate of anapplicant or of a person holding an at-tributable interest in an applicant(both referred to herein as ‘‘the appli-cant’’) if such individual or entity:

(i) Directly or indirectly controls orhas the power to control the applicant,or

(ii) Is directly or indirectly con-trolled by the applicant, or

(iii) Is directly or indirectly con-trolled by a third party or parties thatalso controls or has the power to con-trol the applicant, or

(iv) Has an ‘‘identity of interest’’with the applicant.

(2) Nature of control in determining af-filiation. (i) Every business concern isconsidered to have one or more partieswho directly or indirectly control orhave the power to control it. Controlmay be affirmative or negative and itis immaterial whether it is exercised solong as the power to control exists.

Example for paragraph (h)(2)(i). An appli-cant owning 50 percent of the voting stock ofanother concern would have negative powerto control such concern since such party canblock any action of the other stockholders.Also, the bylaws of a corporation may per-mit a stockholder with less than 50 percentof the voting to block any actions taken bythe other stockholders in the other entity.Affiliation exists when the applicant has thepower to control a concern while at the sametime another person, or persons, are in con-trol of the concern at the will of the party orparties with the power of control.

(ii) Control can arise through stockownership; occupancy of director, offi-cer or key employee positions; contrac-tual or other business relations; orcombinations of these and other fac-tors. A key employee is an employee

who, because of his/her position in theconcern, has a critical influence in orsubstantive control over the operationsor management of the concern.

(iii) Control can arise through man-agement positions where a concern’svoting stock is so widely distributedthat no effective control can be estab-lished.

Example for paragraph (h)(2)(iii). In a cor-poration where the officers and directorsown various size blocks totaling 40 percent ofthe corporation’s voting stock, but no officeror director has a block sufficient to give himor her control or the power to control andthe remaining 60 percent is widely distrib-uted with no individual stockholder having astock interest greater than 10 percent, man-agement has the power to control. If personswith such management control of the otherentity are persons with attributable inter-ests in the applicant, the other entity will bedeemed an affiliate of the applicant.

(3) Identity of interest between andamong persons. Affiliation can arise be-tween or among two or more personswith an identity of interest, such asmembers of the same family or personswith common investments. In deter-mining if the applicant controls or iscontrolled by a concern, persons withan identity of interest will be treatedas though they were one person.

Example 1 for paragraph (h)(3) introductorytext. Two shareholders in Corporation Y eachhave attributable interests in the same SMRapplication. While neither shareholder hasenough shares to individually control Cor-poration Y, together they have the power tocontrol Corporation Y. The two shareholderswith these common investments (or identityor interest) are treated as though they areone person and Corporation Y would bedeemed an affiliate of the applicant.

Example 2 for paragraph (h)(3) introductorytext. One shareholder in Corporation Y,shareholder A, has an attributable interestin a SMR application. Another shareholderin Corporation Y, shareholder B, has a non-attributable interest in the same SMR appli-cation. While neither shareholder has enoughshares to individually control Corporation Y,together they have the power to control Cor-poration Y. Through the common invest-ment of shareholders A and B in the SMR ap-plication, Corporation Y would still bedeemed an affiliate of the applicant.

(i) Spousal affiliation. Both spousesare deemed to own or control or havethe power to control interests owned orcontrolled by either of them, unless


499


they are subject to a legal separationrecognized by a court of competent ju-risdiction in the United States.

(ii) Kinship affiliation. Immediatefamily members will be presumed toown or control or have the power tocontrol interests owned or controlledby other immediate family members.In this context ‘‘immediate familymember’’ means father, mother, hus-band, wife, son, daughter, brother, sis-ter, father- or mother-in-law, son- ordaughter-in-law, brother- or sister-in-law, step-father, or -mother, step-brother, or -sister, step-son, or -daugh-ter, half brother or sister. This pre-sumption may be rebutted by showingthat

(A) The family members are es-tranged,

(B) The family ties are remote, or(C) The family members are not

closely involved with each other inbusiness matters.

Example for paragraph (h)(3)(ii). A owns acontrolling interest in Corporation X. A’ssister-in-law, B, has an attributable interestin an SMR application. Because A and Bhave a presumptive kinship affiliation, A’sinterest in Corporation X is attributable toB, and thus to the applicant, unless B rebutsthe presumption with the necessary showing.

(4) Affiliation through stock ownership.(i) An applicant is presumed to controlor have the power to control a concernif he or she owns or controls or has thepower to control 50 percent or more ofits voting stock.

(ii) An applicant is presumed to con-trol or have the power to control a con-cern even though he or she owns, con-trols or has the power to control lessthan 50 percent of the concern’s votingstock, if the block of stock he or sheowns, controls or has the power to con-trol is large as compared with anyother outstanding block of stock.

(iii) If two or more persons eachowns, controls or has the power to con-trol less than 50 percent of the votingstock of a concern, such minority hold-ings are equal or approximately equalin size, and the aggregate of these mi-nority holdings is large as comparedwith any other stock holding, the pre-sumption arises that each one of thesepersons individually controls or hasthe power to control the concern; how-ever, such presumption may be rebut-

ted by a showing that such control orpower to control, in fact, does notexist.

(5) Affiliation arising under stock op-tions, convertible debentures, and agree-ments to merge. Stock options, convert-ible debentures, and agreements tomerge (including agreements in prin-ciple) are generally considered to havea present effect on the power to controlthe concern. Therefore, in making asize determination, such options, de-bentures, and agreements will gen-erally be treated as though the rightsheld thereunder had been exercised.However, neither an affiliate nor an ap-plicant can use such options and deben-tures to appear to terminate its con-trol over another concern before it ac-tually does so.

Example 1 for paragraph (h)(5). If companyB holds an option to purchase a controllinginterest in company A, who holds an attrib-utable interest in an SMR application, thesituation is treated as though company Bhad exercised its rights and had becomeowner of a controlling interest in companyA. The gross revenues of Company B must betaken into account in determining the size ofthe applicant.

Example 2 for paragraph (h)(5). If a largecompany, BigCo, holds 70% (70 to 100 out-standing shares) of the voting stock of com-pany A, who holds an attributable interest inan SMR application, and gives a third party,SmallCo, an option to purchase 50 of the 70shares owned by BigCo, BigCo will be deemedto be an affiliate of company, and thus theapplicant, until SmallCo actually exercisesits options to purchase such shares. In orderto prevent BigCo from circumventing the in-tent of the rule which requires such optionsto be considered on a fully diluted basis, theoption is not considered to have present inthis case.

Example 3 for paragraph (h)(5). If companyA has entered into an agreement to mergewith company B in the future, the situationis treated as though the merger has takenplace.

(6) Affiliation under voting trusts. (i)Stock interests held in trust shall bedeemed controlled by any person whoholds or shares the power to vote suchstock, to any person who has the solepower to sell such stock, and to anyperson who has the right to revoke thetrust at will or to replace the trusteeat will.

(ii) If a trustee has a familial, per-sonal or extra-trust business relation-ship to the grantor or the beneficiary,


500

47 CFR Ch. I (10–1–98 Edition)§ 90.815

the stock interests held in trust will bedeemed controlled by the grantor orbeneficiary, as appropriate.

(iii) If the primary purpose of a vot-ing trust, or similar agreement, is toseparate voting power from beneficialownership of voting stock for the pur-pose of shifting control of or the powerto control a concern in order that suchconcern or another concern may meetthe Commission’s size standards, suchvoting trust shall not be consideredvalid for this purpose regardless ofwhether it is or is not recognized with-in the appropriate jurisdiction.

(7) Affiliation through common manage-ment. Affiliation generally arises whereofficers, directors, or key employeesserve as the majority or otherwise asthe controlling element of the board ofdirectors and/or the management of an-other entity.

(8) Affiliation through common facili-ties. Affiliation generally arises whereone concern shares office space and/oremployees and/or other facilities withanother concern, particularly wheresuch concerns are in the same or relat-ed industry or field of operations, orwhere such concerns were formerly af-filiated, and through theses sharing ar-rangements one concern has control, orpotential control, of the other concern.

(9) Affiliation through contractual rela-tionships. Affiliation generally ariseswhere one concern is dependent uponanother concern for contracts and busi-ness to such a degree that one concernhas control, or potential control, of theother concern.

(10) Affiliation under joint venture ar-rangements. (i) A joint venture for sizedetermination purposes is an associa-tion of concerns and/or individuals,with interests in any degree or propor-tion, formed by contract, express of im-plied, to engage in and carry out a sin-gle, specific business venture for jointprofit for which purpose they combinetheir efforts, property, money, skilland knowledge, but not on a continu-ing or permanent basis for conductingbusiness generally. The determinationwhether an entity is a joint venture isbased upon the facts of the business op-eration, regardless of how the businessoperation may be designated by theparties involved. An agreement toshare profits/losses proportionate to

each party’s contribution to the busi-ness operation is a significant factor indetermining whether the business oper-ation is a joint venture.

(ii) The parties to a joint venture areconsidered to be affiliated with eachother.

§ 90.816 Criteria for comparative 900MHz SMR renewal proceedings.

(a) Ultimate issue. The ultimate issuein comparative renewal proceedingswill be to determine, in light of theevidence adduced in the proceeding,what disposition of the applications

would best serve the public interest,convenience and necessity.

(b) Renewal expectancies. The mostimportant comparative factor to beconsidered in a comparative 900 MHzSMR renewal proceeding is a majorpreference, commonly referred to as a‘‘renewal expectancy’’.

(1) The 900 MHz SMR renewal appli-cant involved in a comparative renewalproceeding will receive a renewal ex-pectancy, if its past record for the rel-evant license period demonstrates that:

(i) The renewal applicant has pro-vided ‘‘substantial’’ service during itspast license term. ‘‘Substantial’’ serv-ice is defined as service which is sound,favorable, and substantially above alevel of mediocre service which justmight minimally warrant renewal; and

(ii) The renewal applicant has sub-stantially complied with applicableFCC rules, policies and the Commu-nications Act of 1934, as amended.

(2) In order to establish its right to arenewal expectancy, a 900 MHz renewalapplicant involved in a comparative re-newal proceeding must submit a show-ing explaining why it should receive arenewal expectancy. At a minimum,this showing must include:

(i) A description of its current servicein terms of geographic coverage andpopulation served;

(ii) An explanation of its record of ex-pansion, including a timetable of theconstruction of new base sites to meetchanges in demand for SMR service;

(iii) A description of its investmentsin its 900 MHz SMR system; and

(iv) Copies of all FCC orders findingthe licensee to have violated the Com-munications Act or any FCC rule orpolicy; and a list of any pending pro-ceedings that relate to any matter de-scribed in paragraph (b)(2) of this sec-tion.

(3) In making its showing of entitle-ment to a renewal expectancy, a re-newal applicant may claim credit forany system modification applicationsthat were pending on the date it filedits renewal application. Such creditwill not be allowed if the modificationapplication is dismissed or denied.

[62 FR 41221, July 31, 1997]

§ 90.912 Definitions.(a) Scope. The definitions in this sec-

tion apply to §§ 90.910 and 90.911, unlessotherwise specified in those sections.

(b) Small business; very small business;consortium of small businesses; consor-tium of very small businesses. (1) A smallbusiness is an entity that together withits affiliates and controlling principals,has average gross revenues that do notexceed $15 million for the three preced-ing years; or

(2) A very small business is an entitythat together with its affiliates andcontrolling principals, has average


507


gross revenues that do not exceed $3million for the three preceding years.

(3) For purposes of determiningwhether an entity meets the $3 millionor $15 million average annual gross rev-enues size standard set forth in para-graph (b)(1) of this section, the grossrevenues of the entity, its affiliates,and controlling principals shall be con-sidered on a cumulative basis and ag-gregated.

(4) A consortium of small business is aconglomerate organization formed as ajoint venture between or among mutu-ally-independent business firms, eachof which individually satisfies the defi-nition of a small business in para-graphs (b)(1) of this section. In a con-sortium of small businesses, each indi-vidual member must establish its eligi-bility as a small business, as defined inthis section.

(5) A consortium of very small businessis a conglomerate organization formedas a joint venture between or amongmutually-independent business firms,each of which individually satisfies thedefinition of a very small business inparagraph (b)(2) of this section. In aconsortium of small businesses, eachindividual member must establish itseligibility as a very small business, asdefined in this section.

(c) Gross revenues. Gross revenuesshall mean all income received by anentity, whether earned or passive, be-fore any deductions are made for costsof doing business (e.g., cost of goodssold). Gross revenues are evidenced byaudited financial statements for therelevant number of calendar or fiscalyears preceding the filing of the appli-cant’s short-form application (FCCForm 175). If an entity was not in exist-ence for all or part of the relevant pe-riod, gross revenues shall be evidencedby the audited financial statements ofthe entity’s predecessor-in-interest or,if there is no identifiable predecessor-in-interest, unaudited financial state-ments certified by the applicant as ac-curate. When an applicant does nototherwise use audited financial state-ments, its gross revenues may be cer-tified by its chief financial officer orits equivalent.

(d) Affiliate—(1) Basis for affiliation.An individual or entity is an affiliate

of an applicant if such individual or en-tity:



(iii) Is directly or indirectly con-trolled by a third party or parties whoalso control or have the power to con-trol the applicant, or



Example for paragraph (d)(2)(i) of this sec-tion. An applicant owning 50 percent of thevoting stock of another concern would havenegative power to control such concern sincesuch party can block any action of the otherstockholders. Also, the bylaws of a corpora-tion may permit a stockholder with lessthan 50 percent of the voting stock to blockany actions taken by the other stockholdersin the other entity. Affiliation exists whenthe applicant has the power to control a con-cern while at the same time another person,or persons, are in control of the concern atthe will of the party or parties with thepower of control.

(ii) Control can arise through stockownership; occupancy of director, offi-cer, or key employee positions; con-tractual or other business relations; orcombinations of these and other fac-tors. A key employee is an employeewho, because of his/her position in theconcern, has a critical influence in orsubstantive control over the operationsor management of the concern.

(iii) Control can arise through man-agement positions if the voting stockis so widely distributed that no effec-tive control can be established.

Example for paragraph (d)(2)(iii) of this sec-tion. In a corporation where the officers anddirectors own various size blocks of stock to-taling 40 percent of the corporation’s votingstock, but no officer or director has a blocksufficient to give him/her control or thepower to control and the remaining 60 per-cent is widely distributed with no individualstockholder having a stock interest greaterthan 10 percent, management has the powerto control. If persons with such management


508

47 CFR Ch. I (10–1–98 Edition)§ 90.912

control of the other entity are controllingprincipals of the applicant, the other entitywill be deemed an affiliate of the applicant.

(3) Identity of interest between andamong persons. Affiliation can arise be-tween or among two or more personswith an identity of interest, such asmembers of the same family or personswith common investments. In deter-mining if the applicant controls or iscontrolled by a concern, persons withan identity of interest will be treatedas though they were one person.

(i) Spousal affiliation. Both spousesare deemed to own or control or havethe power to control interests owned orcontrolled by either of them, unlessthey are subject to a legal separationrecognized by a court of competent ju-risdiction in the United States.

(ii) Kinship affiliation. Immediatefamily members will be presumed toown or control or have the power tocontrol interests owned or controlledby other immediate family members.In this context ‘‘immediate familymember’’ means father, mother, hus-band, wife, son, daughter, brother, sis-ter, father- or mother-in-law, son- ordaughter-in-law, brother- or sister-in-law, step-father or -mother, step-broth-er or -sister, step-son or -daughter,half-brother or -sister. This presump-tion may be rebutted by showing that:




Example for paragraph (d)(3)(ii) of this sec-tion. A owns a controlling interest in Cor-poration X. A’s sister-in-law, B, has a con-trolling interest in an SMR application. Be-cause A and B have a presumptive kinshipaffiliation, A’s interest in Corporation X isattributable to B, and thus to the applicant,unless B rebuts the presumption with thenecessary showing.

(4) Affiliation through stock ownership.(i) An applicant is presumed to controlor have the power to control a concernif he/she owns or controls or has thepower to control 50 percent or more ofits voting stock.

(ii) An applicant is presumed to con-trol or have the power to control a con-cern even though he/she owns, controls,or has the power to control less than 50percent of the concern’s voting stock,

if the block of stock he/she owns, con-trols, or has the power to control islarge as compared with any other out-standing block of stock.

(iii) If two or more persons eachowns, controls or has the power to con-trol less than 50 percent of the votingstock of a concern, such minority hold-ings are equal or approximately equalin size, and the aggregate of these mi-nority holdings is large as comparedwith any other stock holding, the pre-sumption arises that each one of thesepersons individually controls or hasthe power to control the concern; how-ever, such presumption may be rebut-ted by a showing that such control orpower to control, in fact, does notexist.


Example 1 for paragraph (d)(5) of this section.If company B holds an option to purchase acontrolling interest in company A, who holdsa controlling interest in an SMR application,the situation is treated as though companyB had exercised its rights and had becomeowner of a controlling interest in companyA. The gross revenues of company B must betaken into account in determining the size ofthe applicant.

Example 2 for paragraph (d)(5) of this section.If a large company, BigCo, holds 70% (70 of100 outstanding shares) of the voting stock ofcompany A, who holds a controlling interestin an SMR application, and gives a thirdparty, SmallCo, an option to purchase 50 ofthe 70 shares owned by BigCo, BigCo will bedeemed to be an affiliate of company A, andthus the applicant, until SmallCo actuallyexercises its options to purchase such shares.In order to prevent BigCo from circumvent-ing the intent of the rule, which requiressuch options to be considered on a fully di-luted basis, the option is not considered tohave present effect in this case.


509


Example 3 for paragraph (d)(5) of this section.If company A has entered into an agreementto merge with company B in the future, thesituation is treated as though the mergerhas taken place.


(ii) If a trustee has a familial, per-sonal or extra-trust business relation-ship to the grantor or the beneficiary,the stock interests held in trust will bedeemed controlled by the grantor orbeneficiary, as appropriate.



(8) Affiliation through common facili-ties. Affiliation generally arises whereone concern shares office space and/oremployees and/or other facilities withanother concern, particularly wheresuch concerns are in the same or relat-ed industry or field of operations, orwhere such concerns were formerly af-filiated, and through these sharing ar-rangements one concern has control, orpotential control, of the other concern.


(10) Affiliation under joint venture ar-rangements. (i) A joint venture for sizedetermination purposes is an associa-

tion of concerns and/or individuals,with interests in any degree or propor-tion, formed by contract, express orimplied, to engage in and carry out asingle, specific business venture forjoint profit for which purpose theycombine their efforts, property, money,skill and knowledge, but not on a con-tinuing or permanent basis for con-ducting business generally. The deter-mination whether an entity is a jointventure is based upon the facts of thebusiness operation, regardless of howthe business operation may be des-ignated by the parties involved. Anagreement to share profits/losses pro-portionate to each party’s contributionto the business operation is a signifi-cant factor in determining whether thebusiness operation is a joint venture.

Subpart W—Competitive BiddingProcedures for the 220 MHzService


§ 90.1001 220 MHz service subject tocompetitive bidding.

Mutually exclusive initial applica-tions for 220 MHz geographic area li-censes are subject to competitive bid-ding procedures. The procedures setforth in part 1, subpart Q, of this chap-ter will apply unless otherwise pro-vided in this part.

§ 90.1003 Competitive bidding designfor the 220 MHz service.

A simultaneous multiple round auc-tion will be used to choose from amongmutually exclusive initial applicationsfor 220 MHz geographic area licenses,unless the Commission specifies other-wise by Public Notice prior to the com-petitive bidding procedure.


(a) Sequencing. The Commission willestablish and may vary the sequence inwhich 220 MHz geographic area licensesare auctioned.

(b) Grouping. The Commission willdetermine which licenses will be auc-tioned simultaneously or in combina-tion.

(c) Minimum bid increments. The Com-mission may, by public announcement


511


before or during an auction, requireminimum bid increments in dollar orpercentage terms.

(d) Stopping rules. The Commissionmay establish stopping rules before orduring an auction in order to termi-nate the auction within a reasonabletime.

(e) Activity rules. The Commissionmay establish activity rules which re-quire a minimum amount of biddingactivity. In the event that the Commis-sion establishes an activity rule in con-nection with a simultaneous multipleround auction, each bidder may requestwaivers of such rule during the auc-tion. The Commission may, by publicannouncement either before or duringthe auction, specify or vary the num-ber of waivers available to each bidder.


The Commission will impose pay-ments on bidders who withdraw highbids during the course of an auction,who default on payments due after anauction terminates, or who are dis-qualified. When the Commission con-ducts a simultaneous multiple roundauction, payments will be calculated asset forth in §§ 1.2104(g) and 1.2109 of thischapter. When the amount of such apayment cannot be determined, a de-posit of up to 20 percent of the amountbid on the license will be required.


Each applicant to participate in com-petitive bidding for 220 MHz geographicarea licenses must submit an applica-tion (FCC Forms 175 and 175–S) pursu-ant to the provisions of § 1.2105 of thischapter.


(a) The Commission will require ap-plicants to submit an upfront paymentprior to the start of a 220 MHz Serviceauction.

§ 90.1013 Long-form application (FCCForm 601).

Each successful bidder for a 220 MHzgeographic area license must submit along-form application (FCC Form 601)within ten (10) business days afterbeing notified by Public Notice that itis the winning bidder. Applications for220 MHz geographic area licenses onFCC Form 601 must be submitted in ac-cordance with § 1.2107 of this chapter,all applicable procedures set forth inthe rules in this part, and any applica-ble Public Notices that the Commis-sion may issue in connection with anauction. After an auction, the Commis-sion will not accept long-form applica-tions for 220 MHz geographic area li-censes from anyone other than the auc-tion winners and parties seeking parti-tioned licenses pursuant to agreementswith auction winners under § 90.1019 ofthis chapter.

§ 90.1017 Bidding credits for smallbusinesses and very small busi-nesses.

(a) Bidding credits. A winning bidderthat qualifies as a small business or aconsortium of small businesses as de-fined in § 90.1021(b)(1) or § 90.1021(b)(4)may use a bidding credit of 25 percentto lower the cost of its winning bid. Awinning bidder that qualifies as a verysmall business or a consortium of verysmall businesses as defined in§ 90.1021(b)(2) or § 90.1021(b)(4) may use abidding credit of 35 percent to lowerthe cost of its winning bid.

(b) Unjust enrichment—Bidding credits.(1) If a small business or very smallbusiness (as defined in §§ 90.1021(b)(1)and 90.1021(b)(2), respectively) that uti-lizes a bidding credit under this sectionseeks to transfer control or assign anauthorization to an entity that is not asmall business or a very small busi-ness, or seeks to make any otherchange in ownership that would resultin the licensee losing eligibility as asmall business or very small business,the small business or very small busi-ness must seek Commission approvaland reimburse the U.S. government forthe amount of the bidding credit, plusinterest based on the rate for ten yearU.S. Treasury obligations applicable onthe date the license was granted, as acondition of approval of the assign-ment, transfer, or other ownershipchange.

(2) If a very small business (as de-fined in § 90.1021(b)(2)) that utilizes abidding credit under this section seeksto transfer control or assign an author-ization to a small business meeting theeligibility standards for a lower bid-ding credit, or seeks to make any otherchange in ownership that would resultin the licensee qualifying for a lowerbidding credit under this section, thelicensee must seek Commission ap-

proval and reimburse the U.S. govern-ment for the difference between theamount of the bidding credit obtainedby the licensee and the bidding creditfor which the assignee, transferee, orlicensee is eligible under this section,plus interest based on the rate for tenyear U.S. Treasury obligations applica-ble on the date the license was granted,as a condition of the approval of suchassignment, transfer, or other owner-ship change.

§ 90.1019 Partitioning anddisaggregation.

(a) Definitions.Disaggregation. The assignment of

discrete portions or ‘‘blocks’’ of spec-trum licensed to a geographic licenseeor qualifying entity.

Partitioning. The assignment of geo-graphic portions of a licensee’s author-ized service area along geopolitical orother geographic boundaries.

(b) Eligibility. (1) Phase I non-nation-wide licensees may apply to partitiontheir licensed geographic service areaor disaggregate their licensed spectrumafter constructing their systems andplacing their in operation or commenc-ing service in accordance with the pro-visions in § 90.725(f) of this part.

(2) Phase I nationwide licensees mayapply to partition their licensed geo-graphic service area or disaggregatetheir licensed spectrum after con-structing at least 40 percent of the geo-graphic areas designated in their appli-cations in accordance with the provi-sions in § 90.725(a) of this part.

(3) Phase II licensees may apply topartition their licensed geographic


513


service area or disaggregate their li-censed spectrum at any time followingthe grant of their licenses.

(4) Phase I and Phase II licensees au-thorized to operate on Channels 161through 170 or Channels 181 through 185are not eligible to partition their geo-graphic service area or disaggregatetheir licensed spectrum.

(5) Parties seeking approval for parti-tioning and disaggregation shall re-quest authorization for partial assign-ment of a license pursuant to § 90.709 ofthis part, as amended.

(c) Technical Standards—(1) Partition-ing. In the case of partitioning, re-quests for authorization for partial as-signment of a license must include, asan attachment, a description of thepartitioned service area. The parti-tioned service area shall be defined bycoordinate points at every 3 degreesalong the partitioned service areaagreed to by both parties, unless eitheran FCC-recognized service area is uti-lized (i.e., Major Trading Area, BasicTrading Area, Metropolitan ServiceArea, Rural Service or Economic Area)or county lines are followed. The geo-graphical coordinates must be specifiedin degrees, minutes and seconds to thenearest second latitude and longitude,and must be based upon the 1983 NorthAmerican Datum (NAD83). In the casewhere an FCC-recognized service areaor county lines are utilized, applicantsneed only list the specific area(s)through use of FCC designations orcounty names that constitute the par-titioned area. In such partitioningcases where an unjust enrichment pay-ment is owed the Commission, the re-quest for authorization for partial as-signment of a license must include, asan attachment, a calculation of thepopulation of the partitioned servicearea and licensed geographic servicearea.


(3) Combined Partitioning andDisaggregation. The Commission willconsider requests for partial assign-ment of licenses that propose combina-tions of partitioning anddisaggregation. In the event that thereis a conflict in the application of thepartitioning and disaggregation rules,the partitioning rules take precedence.

(d) License Term. The license term fora partitioned license area and fordisaggregated spectrum shall be the re-mainder of the original licensee’s li-cense term.

(e) Construction requirements—(1) Re-quirements for partitioning. Phase II EA,Regional or nationwide licensees seek-ing authority to partition must meetone of the following construction re-quirements:

(i) The partitionee may certify thatit will satisfy the applicable construc-tion requirements set forth in §§ 90.767or 90.769 of this part, as applicable, forthe partitioned license area; or

(ii) The original licensee may certifythat it has or will meet its five-yearconstruction requirement and willmeet the ten-year construction re-quirement, as set forth in §§ 90.767 or90.769 of this part, as applicable, for theentire license area. In that case, thepartitionee must only satisfy the re-quirements for ‘‘substantial service,’’as set forth in § 90.743(a)(1) of this part,for the partitioned license area by theend of the original ten-year licenseterm of the licensee.

(iii) Applications requesting partialassignments of license for partitioningmust include a certification by eachparty as to which of the above con-struction options they select.

(iv) Partitionees must submit sup-porting documents showing compliancewith the respective construction re-quirements within the appropriate five-year and ten-year construction bench-marks set forth in § 90.767 or 90.769 ofthis part, as applicable.

(v) Failure by any partitionee tomeet its respective construction re-quirements will result in the auto-matic cancellation of the partitionedlicense without further Commission ac-tion.

(2) Requirements for disaggregation.Parties seeking authority todisaggregate spectrum from a Phase IIEA, Regional or nationwide license,must submit with their partial assign-ment application a certification signedby both parties stating which of theparties will be responsible for meetingthe five-year and ten-year constructionrequirements for the particular marketas set forth in § 90.767 or 90.769 of thispart, as applicable. Parties may agree


514

47 CFR Ch. I (10–1–98 Edition)§ 90.1021

to share responsibility for meeting theconstruction requirements. If oneparty accepts responsibility for meet-ing the construction requirements andlater fails to do so, then its license willcancel automatically without furtherCommission action. If both parties ac-cept responsibility for meeting theconstruction requirements and laterfail to do so, then both their licenseswill cancel automatically without fur-ther Commission action.

EFFECTIVE DATE NOTE: At 63 FR 49295,Sept. 15, 1998, § 90.1019 was revised, effectiveNov. 16, 1998. For the convenience of theuser, the superseded text is set forth as fol-lows:

§ 90.1019 Eligibility for partitioned licenses.If partitioned licenses are being applied for

in conjunction with a license(s) to be award-ed through competitive bidding procedures—

(a) The applicable procedures for filingshort-form applications and for submittingupfront payments and down payments con-tained in this chapter shall be followed bythe applicant, who must disclose as part ofits short-form application all parties toagreement(s) with or among other entities topartition the license pursuant to this sec-tion, if won at auction (see 47 CFR1.2105(a)(2)(viii));

(b) Each party to an agreement to parti-tion the license must file a long-form appli-cation (FCC Form 600) for its respective, mu-tually agreed-upon geographic license areatogether with the application for the remain-der of the geographic license area filed bythe auction winner.

(c) If the partitioned license is being ap-plied for as a partial assignment of the geo-graphic area license following grant of theinitial license, request for authorization forpartial assignment of a license shall be madepursuant to § 90.153.

§ 90.1021 Definitions concerning com-petitive bidding process.

(a) Scope. The definitions in this sec-tion apply to §§ 90.1001 through 90.1025,unless otherwise specified in those sec-tions.

(b) Small business; very small business;consortium of small businesses or verysmall businesses. (1) A small business isan entity that, together with its affili-ates and controlling principals, has av-erage gross revenues that are not morethan $15 million for the preceding threeyears.

(2) A very small business is an entitythat, together with its affiliates andcontrolling principals, has averagegross revenues that are not more than$3 million for the preceding threeyears.

(3) For purposes of determiningwhether an entity meets either of thedefinitions set forth in paragraph (b)(1)or (b)(2) of this section, the gross reve-nues of the entity, its affiliates, andcontrolling principals shall be consid-ered on a cumulative basis and aggre-gated.

(4) A consortium of small businesses(or a consortium of very small busi-nesses) is a conglomerate organizationformed as a joint venture between oramong mutually independent businessfirms, each of which individually satis-fies the definition in paragraph (b)(1) ofthis section or each of which individ-ually satisfies the definition in para-graph (b)(2) of this section. Where anapplicant (or licensee) is a consortiumof small businesses (or very small busi-nesses), the gross revenues of eachsmall business (or very small business)shall not be aggregated.

(c) Gross revenues. Gross revenuesshall mean all income received by anentity, whether earned or passive, be-fore any deductions are made for costsof doing business (e.g., cost of goodssold). Gross revenues are evidenced byaudited financial statements for therelevant number of calendar or fiscalyears preceding the filing of the appli-cant’s short-form application (FCCForm 175). If an entity was not in exist-ence for all or part of the relevant pe-riod, gross revenues shall be evidencedby the audited financial statements ofthe entity’s predecessor-in-interest or,if there is no identifiable predecessor-in-interest, unaudited financial state-ments certified by the applicant as ac-curate. When an applicant does nototherwise use audited financial state-ments, its gross revenues may be cer-tified by its chief financial officer orits equivalent.

(d) Affiliate—(1) Basis for affiliation.An individual or entity is an affiliateof an applicant if such individual or en-tity:



515



(iii) Is directly or indirectly con-trolled by a third party or parties whoalso control or have the power to con-trol the applicant, or



Example for paragraph (d)(2)(i). An appli-cant owning 50 percent of the voting stock ofanother concern would have negative powerto control such concern since such party canblock any action of the other stockholders.Also, the bylaws of a corporation may per-mit a stockholder with less than 50 percentof the voting stock to block any actionstaken by the other stockholders in the otherentity. Affiliation exists when the applicanthas the power to control a concern while atthe same time another person, or persons,are in control of the concern at the will ofthe party or parties with the power of con-trol.

(ii) Control can arise through stockownership; occupancy of director, offi-cer, or key employee positions; con-tractual or other business relations; orcombinations of these and other fac-tors. A key employee is an employeewho, because of his/her position in theconcern, has a critical influence in orsubstantive control over the operationsor management of the concern.

(iii) Control can arise through man-agement positions if the voting stockis so widely distributed that no effec-tive control can be established.

Example for paragraph (d)(2)(iii). In a cor-poration where the officers and directorsown various size blocks of stock totaling 40percent of the corporation’s voting stock,but no officer or director has a block suffi-cient to give him/her control or the power tocontrol and the remaining 60 percent is wide-ly distributed with no individual stockholderhaving a stock interest greater than 10 per-cent, management has the power to control.If persons with such management control ofthe other entity are controlling principals ofthe applicant, the other entity will bedeemed an affiliate of the applicant.

(3) Identity of interest between andamong persons. Affiliation can arise be-tween or among two or more persons

with an identity of interest, such asmembers of the same family or personswith common investments. In deter-mining if the applicant controls or iscontrolled by a concern, persons withan identity of interest will be treatedas though they were one person.

(i) Spousal affiliation. Both spousesare deemed to own or control or havethe power to control interests owned orcontrolled by either of them, unlessthey are subject to a legal separationrecognized by a court of competent ju-risdiction in the United States.

(ii) Kinship affiliation. Immediatefamily members will be presumed toown or control or have the power tocontrol interests owned or controlledby other immediate family members.In this context ‘‘immediate familymember’’ means father, mother, hus-band, wife, son, daughter, brother, sis-ter, father- or mother-in-law, son- ordaughter-in-law, brother- or sister-in-law, step-father or -mother, step-broth-er or -sister, step-son or -daughter,half-brother or -sister. This presump-tion may be rebutted by showing that:




Example for paragraph (d)(3)(ii). A owns acontrolling interest in Corporation X. A’ssister-in-law, B, has a controlling interest ina 220 MHz service geographic area license ap-plication. Because A and B have a presump-tive kinship affiliation, A’s interest in Cor-poration X is attributable to B, and thus tothe applicant, unless B rebuts the presump-tion with the necessary showing.

(4) Affiliation through stock ownership.(i) An applicant is presumed to controlor have the power to control a concernif he/she owns or controls or has thepower to control 50 percent or more ofits voting stock.

(ii) An applicant is presumed to con-trol or have the power to control a con-cern even though he/she owns, controls,or has the power to control less than 50percent of the concern’s voting stock,if the block of stock he/she owns, con-trols, or has the power to control islarge as compared with any other out-standing block of stock.


516

47 CFR Ch. I (10–1–98 Edition)§ 90.1021

(iii) If two or more persons eachowns, controls or has the power to con-trol less than 50 percent of the votingstock of a concern, such minority hold-ings are equal or approximately equalin size, and the aggregate of these mi-nority holdings is large as comparedwith any other stock holding, the pre-sumption arises that each one of thesepersons individually controls or hasthe power to control the concern; how-ever, such presumption may be rebut-ted by a showing that such control orpower to control, in fact, does notexist.


Example 1 for paragraph (d)(5). If companyB holds an option to purchase a controllinginterest in company A, who holds a control-ling interest in a 220 MHz service geographicarea license application, the situation istreated as though company B had exercisedits rights and had become owner of a control-ling interest in company A. The gross reve-nues of company B must be taken into ac-count in determining the size of the appli-cant.

Example 2 for paragraph (d)(5). If a largecompany, BigCo, holds 70% (70 of 100 out-standing shares) of the voting stock of com-pany A, who holds a controlling interest in a220 MHz service geographic area license ap-plication, and gives a third party, SmallCo,an option to purchase 50 of the 70 sharesowned by BigCo, BigCo will be deemed to bean affiliate of company A, and thus the ap-plicant, until SmallCo actually exercises itsoptions to purchase such shares. In order toprevent BigCo from circumventing the in-tent of the rule, which requires such optionsto be considered on a fully diluted basis, theoption is not considered to have present ef-fect in this case.

Example 3 for paragraph (d)(5). If companyA has entered into an agreement to mergewith company B in the future, the situation

is treated as though the merger has takenplace.


(ii) If a trustee has a familial, per-sonal or extra-trust business relation-ship to the grantor or the beneficiary,the stock interests held in trust will bedeemed controlled by the grantor orbeneficiary, as appropriate.



(8) Affiliation through common facili-ties. Affiliation generally arises whereone concern shares office space and/oremployees and/or other facilities withanother concern, particularly wheresuch concerns are in the same or relat-ed industry or field of operations, orwhere such concerns were formerly af-filiated, and through these sharing ar-rangements one concern has control, orpotential control, of the other concern.


(10) Affiliation under joint venture ar-rangements. (i) A joint venture for sizedetermination purposes is an associa-tion of concerns and/or individuals,


517


with interests in any degree or propor-tion, formed by contract, express orimplied, to engage in and carry out asingle, specific business venture forjoint profit for which purpose theycombine their efforts, property, money,skill and knowledge, but not on a con-tinuing or permanent basis for con-ducting business generally. The deter-mination whether an entity is a jointventure is based upon the facts of thebusiness operation, regardless of howthe business operation may be des-ignated by the parties involved. Anagreement to share profits/losses pro-portionate to each party’s contributionto the business operation is a signifi-cant factor in determining whether thebusiness operation is a joint venture.


§ 90.1023 Certifications, disclosures,records maintenance and audits.
