5GHz Study Group Original Intent

Standard Harmonization - Single Global Standard for 5GHz WLANs

International effortIEEE, ETSI, MMAC

Interim ObjectiveInterworking mechanism (TGj)

Interworking Proposal ConceptsLegacy backward compatibility maintainedApproaches so far based upon superframes using either DCF or PCF

HCF now being investigatedLikely to have no impact on Client, AP implementation only

Future plan5GHz Partnership Project now called 5WING

Motions• The SG recommends a motion to the 802.11 WG to

reconsider the approval and forwarding to Exec Com of the PAR and 5 criteria for TGj (Doc 01-172, 01-173) – Approved in SG 13-0-13

• Motion to extend the 5GSG until the November plenary with the original goals as previously adopted, allowing a joint discussion with the other standards bodies (ETSI BRAN, MMAC) in the September 2001 meeting of the Joint SG to refine the aforementioned goals.– Approved in SG 21-2-2

• Background– Attempt to split the activity of the 5GSG into two groups– TGj and 5WING, where 5WING would look at future networks

Motion

• Motion to amend something previously adopted

• Amend the motion to substitute “rescind” for “reconsider” resulting in the following motion to be presented in the Closing Plenary:

• The SG recommends a motion to the 802.11 WG to rescind the approval and forwarding to Exec Com of the PAR and 5 criteria for TGj (Doc 01-172, 01-173)

Coordination Remains Important

• Three way Joint Study Group

– (IEEE, ETSI/BRAN, MMAC)

• Alternating ETSI and IEEE meeting venues

• Co-located meetings in September 2001

– (More) Formal representation from MMAC

BRAN #24 Activity

European Telecommunications Standards InstituteBRAN#24 26 June to 29 June 2001Sophia-Antipolis, France

Executive Summary - BRAN24d141 1. Defer decision to continue/discontinue the Inter-

working project until after the IEEE meeting in Portland. It was noted that both BRAN and IEEE will be meeting during the same week in September in Seattle and a joint meeting at that time would be desirable and presumably easy to arrange.

MMAC Notice of Reorganization and Activities

• MMAC letter to ETSI BRAN and IEEE (BRAN24d140) • Announcing reorganization• The Convergence Ad-hoc Study Group of MMAC-PC (a.k.a CASG) met on 23rd

May, 2001 to discuss how to proceed towards convergence of MMAC wireless systems, HiperLAN2 and IEEE802.11a using 5 GHz band

• CSMA WG work is done and will be closed soon.• CSMA members shall directly participate in 5GSG/IEEE802.11 meetings

representing each company for the globalization discussion, if necessary. • MMAC-PC will continue to work together with ETSI-BRAN and IEEE802.11

members within joint 5GSG framework for short term harmonization.• CASG participants agreed to create a new group to work toward a single

standard of the next generation wireless LAN including wireless Homelink applications using 5GHz band. This new group will be a joint group comprising HiSWANa members and Wireless Homelink members of MMAC-PC.

• Reorganization – Nominate TK Tan as chair in 5GSG

– Nominate Bruce Kraemer as co-vice chair

– Any other nominations from the floor?

– A recommendation from 5GSG subject to approval by Stuart in 802 WG

– Result: Unanimous consent (37 attendees)

Amend something previously adopted

• This is a motion that can be used if it is desired to change only a part of the text or to substitute a different version.

• This requires a two-thirds vote

Submission

Rescind

• A motion by which a previous action or order can be canceled or counter mended.

• The effect of rescind is to strike out an entire main motion that has been adopted at some previous time

• This requires a two-thirds vote

Reconsider

• Reconsider – enables a majority in an assembly to bring back for further consideration a motion which has already been voted on.

• The purpose of reconsidering a vote is to permit correction of hasty, ill-advised or erroneous action, or to take into account added information or a changed situation that has developed since the taking of the vote– It can only be made by a member on the prevailing side during the

session at which the original motion was approved.

Scope of Proposed Project:Establish coexistence and inter-working among the 802.11a, ETSI HiperLAN/2, MMAC CSMA and HiSWANa standards. Extension of each of the MAC and PHY layers of these standards will be defined collaboratively to achieve coexistence and inter-working.

Purpose of Proposed Project:To establish coexistence and inter-working among the 802.11a, ETSI HiperLAN/2, MMAC CSMA and HiSWANa standards. A subsequent project under a separate PAR is to create a single converged standard in the 5GHz band.

History of 5GSG Formation• Liaisons on PHY during creation of 802.11a and HL2 (’98-’99)

– Substantial harmonization

• Initiated by 5GWLIAG (May 2000) – to address problems of multiple standards at 5Ghz space

• Letters exchanged on request to recognize 802.11a as a member of HL2 (Jul 2000)– Led to ETSI joining the Sept 2000 IEEE meeting

• Creation of Joint 5GSG (Sept 2000)– Alternative meeting venues

• 5Ghz Global Standardization and Convergence discussion - IEEE September meeting, Scottsdale

• Industry consensus towards global standardization at 5Ghz• Request for an 802.11 Study group (with coordination with ETSI BRAN and

MMAC) to address these issues.• LMSC Nov 9, 2000 approved formation of 5GSG (with contingencies of forming

similar groups at ETSI BRAN and MMAC were fulfilled)
