1 INTRODUCTON TO REPEATER

A repeater, in concept is a device that receives a signal, filters and retransmits the amplified version of the signal. This is simultaneously done for both up and downlink frequencies. Repeater systems are typically located in places of high elevation (on mountains and tall buildings) and are equipped with highly directional donor antennas and service antennas appropriately selected for the application, low loss feedlines, and a very reliable transmitter and receiver rated for continuous duty. Repeaters allow signal coverage to be extended into areas previously not covered without the need to add additional BTS infrastructure. Repeaters are used in Commercial Communications, Emergency Communications. Repeaters may have multiple powering options, including batteries for when commercial power is lost. Repeaters can be built that may run exclusively from batteries; recharged by solar or renewable energies. 1.1 REPEATER APPLICATION

A repeater works as a bi-directional amplifier to enhance the signal between mobiles and base stations, in uplink and downlink direction.

Used for an area with poor coverage in outdoor and indoor environment, or for coverage enhancements in areas blocked by obstacles.

Uses a pick up (donor) antenna to receive and amplify the radio signal from a donor cell, and then retransmits from an antenna mounted near the area to be covered.

AGC limits intermodulation to a fixed level during overload. Complete local monitor function and powerful remote repeater network administration (OMC).

Typical applications include

Indoor: conference centre, shopping mall, office building. Radio shadow areas: underground car parks, tunnels, valleys. Coverage extension: motorways, remote villages.

Figure 1: Typical Repeater Setup



Using a repeater can achieve the following benefits:

Fast rollout and fast coverage leads to fast return on investment Low build out costs For GSM network, no planning of BSS parameter No microwave link and No 2 Mbit- connection needed Less antennas and cable usage, and much lighter steel hardware A strong tower is not required. Easy to locate site for installation & coverage Expands coverage areas in: rural, tunnels, in-building, canyons and highways Platform for subscriber growth

AVS repeater types include:

Broadband repeater Band-selective repeater Channel-selective repeater Fiber-optic repeater Frequency-shifting repeater

In this manual we will focus on AVS BSR 933 C band selective repeater. 1.2 BAND SELECTIVE REPEATERS

Band selective repeaters amplify and retransmit all signals within a defined frequency band and are mainly used for coverage of dead zones, shadows, in-building coverage or other areas with inadequate signal strength. The band selective repeater is very suitable for applications where frequency hopping is used in the BTS network employing Time Division Multiple Access.

Figure 2: Band Selective Repeater



1.3 CHANNEL SELECTIVE REPEATERS

Channel selective repeaters have the same functionality as band selective repeaters. The difference is that channel selective repeaters separate out specific carriers and amplify and retransmit all signals within a defined frequency channel. In a channel selective repeater each carrier is separately filtered, amplified and retransmitted. A channel selective repeater from AVS can have 1 to 8 channels. Channel selective repeaters may have higher output power per carrier and the maximum output power per carrier can be several watts.

Figure 3: GSM Channel Selective Repeater



1.4 AVS BSR 933 C REPEATER INTRODUCTION

The AVS BSR 933 C dual band selective repeater is designed for outdoor operation in the GSM900 system. A band-specific linear amplifier and filter effectively amplifies the desired BTS carriers and provides superior out-of-band rejection. Typical units incorporate up to 15MHz adjustable bandwidth with frequencies programmed to specific requirements within the whole of the GSM900 band. Dual band selectivity is implemented with two band selective filters per UL/DL. Remote configuration and surveillance is possible through AVS’s remote control and monitoring system, via laptop or wireless modem to the OMC. Li-ion backup battery built in enclosure ensures alarm signals are sent out while power is down, and optional external battery backup ensures operation in a condition with insufficient power supply or unstable supply voltages. The AVS BSR 933 C comes in a completely sealed, well-ventilated cast aluminum chassis, suitable for all weather conditions. Main features of AVS BSR 933 C:

Band selectivity from two band-selective modules with user-defined bandwidth. Output power can be easily adjusted via repeater PC software (hereinafter called RPS) software

to satisfy the requirement of network optimization. Integrated GSM radio modem for remote configuration, monitor and control. Automatic elimination for self-oscillation caused by a low isolation between DT and MT

antennas. Internal backup battery keeps the alarm unit running for up to three hours after power loss. Optional OMC is available for remote operation and maintenance of repeaters. Designed for all weather outdoor – waterproof, damp-proof and omni-sealed (IP65).

Figure 13: Erected hinged tray showing FS and PA



2.4.4 MAIN CONTROL UNIT (MCU)

The main control unit (MCU) is the heart of the equipment, it monitors and controls the modules within the repeater. Data is collected from various modules such as PA, LNA and Power Supply utilizing a RS-485 bus. The collected data is processed and if an error is detected the MCU may send an alarm via Datalink or SMS using a built in wireless GSM modem to the Operation and Maintenance Center (OMC). MCU is constructed on a multi-layered PCB and is a plug-in board to the Interface board. Main components are: Motorola 68HC711 processor, non-volatile memory, communication processor, temperature sensor, LEDs and a small push-button switch. This switch is used to reset the equipment when equipment initialization fails, or non-normal operation happens, or when the equipment is re-connected to the RPS after powered off due to some reason. On the MCU there are four LEDs (L1~L4) on which displays the respective operation status. Their functions are described in a separate section.

Output voltage rails from the PSU are fed into the Interface board via a cabling assembly, Voltages rails are DC at +9V (for LNA, FS & PA), +26V (for PA). Connections are made by screw terminals identified as below: Terminal identifier Voltage level -9V GND for +9V +9V +9V DC -5V GND for +5V +5V +5V DC -26V GND for +26V -26V GND for +26V +26V +26V DC +26V +26V DC MD- GSM Modem supply GND MD+ GSM Modem power +12V B2- Battery connection –reserved for future use B2+ Battery connection –reserved for future use B1- Battery connection –reserved for future use B1+ Battery connection –reserved for future use LNE AC mains connection from surge protector The switch on the PSU is provided for convenience, and the 220VAC should be controlled at its outlet. With the equipment under operation, the switch on the PSU should be in the ON position at all times. Once the AC to the PSU removed, the backup Li-ion battery supplies power to the MCU and ensures alarm signals to be sent to the OMC via the RPS software or wireless modem. A customer replaceable fuse protects the AVS BSR 933 C against over current. The fuse holder is identified on the panel of the PSU. Supplied with the equipment are two spare 6.3A delay fuses for the PSU, the PSU is not a customer-repairable item, and should be returned for repair. When replacement of the PSU is necessary, in order to remove the PSU, remove all electrical connections to the PSU, unscrew four screws on each corner of the top mounting surface, which secure the PSU onto the chassis. The mounting surface of the replacement PSU should be coated with a layer of heat transfer compound before it is mounted. After the PSU mounted to the chassis, reconnect all electrical connections.



2.4.7 SURGE PROTECTOR

Surge protectors are mounted next to the PSU for protection from transients caused by thunderstorms and switching process. Within it there are three connections: 220V VAC Live, Neutral and ground. This unit provides protection to the PSU. It is assumed the antenna system will have ample lighting protection themselves. On the top of each lighting arrester is a little window, beneath which is a coloured indicator, ‘Green’ indicate protection is available, and in the event of a fault, these will turn to ‘Black’, and has to be replaced. Replacement is made by griping the edges and gently pulling it out of its socket. The replacing surge protector is inserted by observing its orientation before gently inserting it into the socket.

Figure 17 : Surge protector for power supply

2.4.8 LI-ION BACK-UP BATTERY

The Li-ion backup battery is located on the hinged tray. The Li-ion battery-pack is enclosed within a plastic cover and provides back-up supply to the MCU. An in-line connector close to the battery pack is ‘disconnected’ before shipping. During installation, re-connect the in-line connector to ensure proper function of the MCU. The battery pack is rated at 21.6V, 1300mAh.

Figure 18: Li-ion battery pack



2.4.9 MICRO-SWITCH

Mounted on the lower left of the enclosure is a micro-switch. This is to detect if the door of the AVS BSR 933 C is open. An alarm signal is generated to notify if the AVS BSR 933 C is being ‘opened-up’ in normal use.

Figure 19 : Location of Microswitch



2.4.10 DUPLEXER (DPX)

There are two duplexers, one is located towards the DT connection and the other towards MT connection. Their function is to combine/divide the uplink and downlink signals as well as select the required signals and reject the unwanted signals. Each DPX has four connections: For the DPX towards the DT connection, the connections are shown as below: Tx: Connection for DL LNA ANT: Connection for DT port Rx: Connection for UL PA 20dB coupling port: Connection for GSM Modem, used for coupling RF signals from GSM

Modem. This port is only regard to the DT ANT connector. For the DPX towards the MT connection, the connections are shown as below: Tx: Connection for DL PA ANT: Connection for MT port Rx: Connection for UL LNA 20dB coupling port: Connection for RF signal, used for detecting UL signals from service

antenna or DL signals transmitted by repeater (reserved for future use)

Figure 20: Duplexer (towards MT Connection) mounted on the hinged tray



2.4.11 GSM MODEM

A GSM wireless modem is mounted adjacent to the MCU, it has connection for RF, data and power. It is used for remote control and the MCU sends out alarms to the repeater OMC via the GSM modem. Required power voltage for GSM modem is +12 V. Power to the GSM modem is provided from the PSU via cabled connection from the Interface Board, and is protected with an in-line fuse. This gives the User the option to disconnect the modem power supply and forcing the modem to be restarted. RF connection is made with SMA connecting cable between the modem and the 20dB coupling port. On the GSM modem there is an indicator LED to show the modem status. The modem LED flashes slowly when operation is normal. When a data call is performed it will flash quickly. When SMS is sent, it flashes a little quicker than when operation is normal but slower than when a data call is ongoing.

In the case of very low donor signal levels the 20dB coupling from the DT DPX to the modem can result in bad connectivity for the modem. 2.4.12 POWER AMPLIFIER (PA)

There are two power amplifiers, UL PA & DL PA, located in UL and DL branch respectively. Their function is to fulfill power amplification in both of uplink and downlink branches. Within the PA, there are three connections for power & MCU signals, RF-in and RF-out. Required power voltage for PA is +9V (for RF) and 5V(for MCU). It is mounted directly to the enclosure for maximum cooling efficiency.



2.4.13 FREQUENCY SELECTOR (FS)

Frequency selector (FS) can select the required signal and reject the other unwanted signals effectively. It is mounted directly to the back of the equipment enclosure. Within the FS there are connections for power & MCU, RF-in and RF-out. And the required power voltage for PA is +9V (for RF) and 5V(for MCU). As a slave unit, the FS is under the direct control of the MCU over a RS-485 bus, each FS uses SAW filters and has four PLL and so giving the equipment superior control of frequency selection and stability. The RPS communicates to the MCU and the MCU communicates to each FS to implement the required operating band edges.



2.4.14 LOW NOISE AMPLIFIER (LNA)

Located along the top edge of the equipment are UL and DL low noise amplifiers (LNAs), these are installed respectively in UL branch and DL branch. The repeater UL/DL ATT value ranges from 0~30dB, and corresponds individually to UL/DL LNA gain (40dB). This LNA is fed by 9V power and operates at 75MHz. The NF for the LNA is 1.5dB.

3 INSTALLATION

3.1 WARNINGS AND ALERTS

Radio Frequency energies There may be situations, particularly the workplace environments adjacent to high-powered RF sources, where recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases, restrictive measures or actions may be necessary to ensure the safe use of RF energy. Assume that other RF energies exist in the vicinity, always maintain a minimum distance of 1m from the human beings (assumption 935 MHz at 40W emitted power, source IEEE) High voltage The equipment has been designed and constructed as to prevent as far as reasonably practicable danger. Any activity, such as installation, operation and maintenance, on or near the equipment must be as far as reasonably free from danger. Where there is a risk of damage to electrical systems due to adverse weather, extreme temperatures, wet, corrosive or dirty conditions, flammable or explosive atmosphere, then the system must be suitably installed to avoid such a danger. To reduce the risk of damage to the equipment and to the customer, shut down the equipment and take action to isolate mains supply when performing any intrusive actions. Protective Earthing Equipment must be well grounded for the purpose of protecting individuals from electrical risk. Handling Precautions Precautions should be taken in equipment handling activities including lifting, lowering, pushing, pulling, carrying, moving or holding, or the activities to prevent an object, animal or other aspects going into the chassis, or the activities when extra efforts are needed such as pulling a lever, or operating power tools. ESD Take necessary precautions when handling ESD-sensitive devices. Assume that all solid-state electronic devices are ESD-sensitive. Do use a grounded wriststrap or the like while working with ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-free environments.



3.2 SITE PLANNING CONSIDERATIONS

Site considerations The repeater is designed to be waterproof, rainproof, and with snow protection. Temporary protection should be taken when the equipment chassis is opened for installation or maintenance in an outdoor environment. The equipment must not be opened for installation or maintenance in bad weather (e.g. gale, storm rainfall, extreme temperatures and high humidity) Installation location Mounting surface shall be suitable to support weight of the equipment: for AVS BSR 933 C, this is about 37 kg (82 lb.). Environmental Humidity has an effect on the reliability of the equipment. It is recommended to install the equipment in location having stable temperature and un-restricted air-flow. AVS BSR 933 C equipment has been designed to operate in the ambient air temperature range of -25C to +55C (-13F to 131F) at ≤ 95% relative humidity. Should the direct day light temperature exceeds +55C (131F), then barrier device should be installed in to protect the equipment to limit sunlight exposure. Powering The power supply unit (PSU) provides power to all modules within the chassis. The PSU accepts 155~285VAC/50Hz±5Hz. It is recommended that the PSU operate on a dedicated AC circuit breaker or fused circuit. In order to avoid electromagnetic interference, select the AVS BSR 933 C mounting location to minimize interference from electromagnetic sources such as high powered equipment. Grounding requirement Verify the equipment has been well grounded, this includes antennas and all cables connected. Ensure lightning protection for the antennas is properly grounded. Cable routing Four cables entries to the equipment: Two co-axial (connection for MT and DT), one 220VAC mains-power cable and 1x RS-232 commission cable during commissioning with the door open. Manual handling During transportation and installation, take necessary handling precautions to avoid potential physical injury to the installation personnel or damages to the equipment.

3.3 SITE PLANNING - LINK BUDGET

It is important to determine the link budget before installation and commissioning to ensure good system performance. In this example these fixed parameters are used:

BTS Parameters Frequency 900MHz BTS uplink noise figure (NFBTSU): 5dB BTS downlink power (PBTS): 40dB BTS Sensitivity −109dBm BTS Feeder Loss (LBTS-feeder) 3dB BTS ANT Gain (GBTS-ant) 15dBi Repeater Parameters DL Max. Gain (Grep-DLmax) 90dB UL Max. Gain (Grep-ULmax) 90dB UL NF (NFrep-UL) 6dB Fade Margin (repeater to MS) (Pmargin) −90dBm NFMS 6dB Donor Antenna Gain (Grep-donor ant) 15dBi Donor Antenna Front/Back Ratio (F/Brep-donor ant) 28dB Donor Feeder Loss (Lrep-donor feeder) 2dB Power Received at Donor Antenna (Prep-receive) −65dBm Service Antenna Gain (Grep-service ant) 18dBi Service Antenna Front/Back Ratio (FBrep-service ant) 28dB Service Antenna Height 3m Path Loss (Lrep-mobile) 120dB MS Parameters MS Max. Output Power (Pmobile) 33dBm



Downlink Path: Fade margin of the coverage area (Pmargin) should satisfy the following:

Rrep-receive + Grep-donor ant −Lrep-donor feeder +Grep-DL −Lrep-mobile =Pmargin −65dBm + 15dBi − 2dB + Grep-DL − 120dB = −90dBm

From above, we derived: Grep-DL = −90dBm + 120dB−(−65dBm) − 15dBi + 2dB =82dB

Thus the downlink master ATT should be: Grep-DLmax −Grep-DL =90−82 =8dB

Note: Grep-DL is the actual downlink Gain after the repeater is installed. Uplink Path: The received power at BTS receiver (PBTS-receive) should satisfy the following formula: PBTS-receive =Pmobile +Grep-UL −Lrep-donor feeder +Grep-donor ant −(PBTS −LBTS-feeder +GBTS-ant −Prep-receive) ≥RBTS

33 −120 +Grep-UL −2 +15 −[40 −3 +15 − (−65)] ≥109

Therefore Grep-UL id determined as 82dB Thus the uplink master ATT should be:

Grep-ULmax −Grep-UL =90 −82 = 8dB

Note: Grep-UL is the actual uplink Gain after the repeater installed.

NFTotal＝NFBTS＋10LOG（1+10（NFrep-UL−NFBTS+Grep-UL- LBTS-REP）/10）= 5dB +1.19dB = 6.19dB Assuming that repeater noise power at MT port equals to −120dBm, then: Repeater noise power at BTS receiver should be:

NFBTS = −120dBm + 82dB −105dB +6.19dB = −136.81dBm The total BTS thermal noise should be:

−121dBm + (−136.81dBm) = −120.8dBm From the results we can see the BTS thermal noise has increased by only 0.2dBm after the insertion of a repeater.



Isolation: In the repeater application, isolation between donor antenna and service antenna should be taken into consideration and satisfy the following:

I ≥ Grep-DL +15dB =97dB Assuming that both donor antenna and service antenna are horizontally installed, then:

I = 32.4+20logf+20logD −(Grep-donor ant +Grep-service ant) +(FBrep-donor ant +FBrep-service ant) I =32.4 +20log(900) +20logD −(12dBi +18dBi) +(28dB +28dB) ≥97dB

From above, we derived D ≥133m Assuming that both donor antenna and service antenna are vertically installed, then:

I =28 +40log(H/λ) − (Grep-donor ant +Grep-service ant) +( FBrep-donor ant +FBrep-service ant) ≥97dB From above, we derived H ≥4.7m



3.3.1 REPEATER INSTALLATION CHECKLIST

Installation Location Requirement Considerations Working Space available Ample space on mounting pole or wall surface.

Recommended: 800mm×800mm×800mm AC power supply at each installation location: 155~285VAC/50Hz±5Hz

Table 7: Antenna installation checklist



3.4 INSTALLATION PROCEDURES

3.4.1 GOODS INWARDS INSPECTION

Verify the number of packages received against the packing list. Check all packages for external damage; report any external damage to the shipping carrier. If

there is damage, a shipping agent should be present before unpacking and inspecting the contents because damage caused during transit is the responsibility of the agent.

Open and check each package against the packing list. If any items are missing, contact AVS. Do not remove items from antistatic packing until installation. If damage is discovered at the time

of installation, contact the shipping agent. 3.4.2 TOOLS

See appendix A for a full list of tools required for new installation and routine maintenance. 3.4.3 PREPARATION

Repeater: Mounting surface or pole capable of support chassis’ weight: < 37 kg (82 lb.) Power outlet within 2m / 6.5 ft. Terminate unused antenna ports with a 50 ohm terminator. Earthing point/Safety ground within 2m / 6.5 ft.

Antenna:

Antenna installation is covered by their respective manuals. Take normal precautions when preparing and handling feeder cables to ensure they are not damaged.



3.4.4 WALL MOUNTING DETAILS

Fix the mounting rack to a wall with four masonary bolts (M10×100). If the mounting surface is not solid enough, insert two more masonary bolts to the upper mounting rack.

Raise the chassis and position it over the mounting rack, hook the equipment chassis onto the mounting rack from the upper corners.

To open the chassis door, first unlock and then using the allen key, remove four socket-head bolts on each corners of the door.

Four bolts (M8×80) secure the chassis to the mounting rack, these are accessed from the rear rack.

Close the chassis cover, tighten the socket-head bolts on four corners and lock the chassis door.

Figure 21: Mounting Rack Dimension



Figure 22: Wall Mounting Overview

3.4.5 POLE MOUNTING DETAILS

The equipment can be mounted on customer-located poles of about 60~75mm in diameter. Insert and tighten the U bolts to secure the mounting frame onto the pole. The remainder of the installation are identical to wall-mounting.

Figure 23: Pole Mounting Overview



3.4.6 DRIP-LOOP

AVS recommends that every horizontal cable entry to the equipment forms a 'U' before its entry to the equipment. Any accumulated water on the cable will drip down at the bottom of the loop and will not climb up to the equipment. 3.4.7 EQUIPMENT CONNECTIONS

The equipment has been designed for all cable entries from the bottom of the chassis. The only exception is the RS232 connection where it is a temporary connection for equipment commissioning. Ground connection The chassis must be grounded securely. Connect a copper wire (resistance <2.5 Ω) to the grounding terminal on the equipment chassis, and connect the other end to a protective ground (i.e. building earth point). An internationally acceptable coloring code of the ground connection wire is green/yellow. Service voltage connection The repeater accepts single phase 220VAC 50Hz power. The recommended AC connection is rated at AC 220V, 10A and has three connections to include earth. This connection is labeled ‘AC in’. RF signal connection Connection to donor antenna and mobile antenna is below:

Donor antenna cable → DT port Mobile antenna cable → MT port

Li-ion battery connection The lithium-ion battery-pack provides back-up supply to the MCU board; an in-line connector close to the battery pack is ‘disconnected’ before shipping. During installation, re-connect the in-line connector to ensure proper function of the MCU. RPS connection for commission and local management

The cable (R-9122C/R-9122AC) is supplied with the equipment. It connects the serial port of the PC to the RS-232 port (DB9) on the interface board within the chassis. Although it is not necessary, it is still recommended to temporarily break the Li-ion battery connection before making the RPS connection. This minimizes the occurrence of transients causing potential damage to either the equipment or the PC.

4 COMMISSIONING

4.1 MCU LED INDICATORS

Four diagnostic LEDs are located on the MCU, each indicates the status of a particular function:

Identifier Colour Indication L1 Red Online programming. This will flash when users read, set or download files

via RPS L2 Red Warning LED, when ON, it indicates alarm condition L3 Green MCU operation. Flashing at a rate of 1 flash/sec. Any other flashing rate

indicates MCU is faulty, and has to be replaced. L4 Red Wireless modem status. During normal operation, it is OFF, while ON, it’s

indicating faulty wireless modem and no communication will take place. Table 8: MCU LED

MCU Initialization Indicators L1~L4 are flashing at the time the equipment is power up, indicating the system is self-checking. About 60 seconds later, L4 turns into ‘Off’ status, and L3 continues flashing, indicating the MCU is under normal operation mode, when OMT/OMC on-line connection could be implemented. But if L4 remains ‘On’, it indicates the modem initialization failed and remote commission is not available.

4.2 EQUIPMENT POWER-UP

Before applying power, check that the expected voltage, current, and power levels do not violate any ratings. Double check all connections before applying power. Do not manipulate circuits or make changes with power applied.



4.3 REPEATER PC SOFTWARE (RPS)

AVS RPS software is based on Windows operation system, and is designed for monitoring and maintaining of AVS repeaters and boosters. RPS is an online software program with an intuitive graphical interface that simplifies control and installation of the repeater. The RPS is a graphical interface to the repeater’s MCU. It reads commands and attributes from the repeater’s MCU and displays them in an intuitive layout. This eliminates the need to learn commands and attributes for controlling the repeater. Login to the repeater can be made by one or two means:

RPS software running on a local PC with serial connection to the equipment AVS OMC software with remote connection to the equipment over wire/wireless

telecommunication network (optional). As soon as the RPS is connected the RPS main window will appear, click ‘Online’ in the window, the RPS constantly polls the repeater for parameters such as power supply levels, input and output levels, temperature, traffic, etc. The RPS software can accomplish the following functions:

Click ‘Quit’ from within the ‘System’ pull-down menu within the RPS main window, select ‘Yes’, the system will exit from the RPS software.



4.8 COMMISSIONING PROCEDURES

System commission can commence after the monitoring system has initialized. (e.g. when MCU LED L4 is off and L3 begin to flash). The commission sequence and procedure is as follow:

Commissioning Tasks Observation Verify RF uplink and downlink power

Locate the DT coupler at the inside left side of chassis. Measure signal from the 20dB coupling port with the DPX at the DT port to verify downlinksignals from BS. Locate the MT coupler at the right side of chassis. Measure signal from the 20dB coupling port within the DPX to verify uplink signals from mobileantenna or downlink signals retransmitted by the repeater.

On-line & inquiry status

Enter into RPS Main window. Initialization of monitoring system will be up in about 2 minutes, at that time, on MCU L4 is off and L3 begins to flash. Click ‘online’ button and inquiry the repeater’s status. Go to next step if there is no alarm. Else or, check the point of failure and handle the alarm.Set site ID and telephone number

Set On/off Status / operating band/ gain

Click ‘ON’ of power supply in the RPS main window and set high edge and low edge of the repeater’s operating frequency, uplink/downlink master ATT (user can set initial value to 20~30dB) and uplink/downlink assistant ATT (factory set value is 0dB, and it is not recommended to use assistant ATT).

Set monitoring system parameters

Test DL input power and align donor antenna

Observe DL input power from ‘Field (dBm)’. Align the direction of donor antenna till the DL input power reading is maximized.

Set monitoring system parameters

Measuring power for UL/DL output levels

Test DL output power and adjust DL ATT level

Set the DL ATT to the optimal level to avoid saturating the DL PA or to satisfy designing requirement.

Test coverage area field intensity and adjust mobile antenna.

Use test-handset to verify field intensity within the coverage area. If needed, re-align the mobile antenna to achieve the coverage as per customer requirement. Note 1: If during operation, the equipment gain could not be set to maximum or the output power is not high enough due to influence of donor antenna and mobile antenna isolation, the value of ‘Is’ should be re-calculated. If the output power has been high enough and ALC is enables, then adjust gain for the downlink branch to achieve ALC to operate within 4~7 dB. Note 2: Output power may be variable due to TDMA technology employed in GSM devices. Take the maximum value when reading parameters.

Verify uplink gain and ensure test-call is proper and there are no interfering BS

Adjust uplink gain and carryout test-call. Set the uplink gain slightly lower than downlink gain. Then carryout test call in the coverage area while adjusting uplink gain if required. Note: If the repeater locates near the BTS and the test-call performance is poor, this may be due to uplink noise interfere the BTS. Customers can calculate whether the repeater uplink noise interfere the BTS according to the table in APPENDIX C. Verify again there’s no unacceptable interference to BTS and Isolation meets the need after test-call.

Table 12: Commissioning procedures

5 OPERATION

Following installation and commissioning, occasional operation tasks to handling alarms may be required:

Alarm condition Diagnosis Power down / power fault alarm

Check AC power cable and verify AC mains supply is normal. During power fault alarm, DC power supply has no output. Check if DC output power is overload or short-circuited. The PSU could be faulty.

Uplink / downlink LNA, uplink / downlink PA, uplink / downlink high/low edge PLL alarms handling

Check power and signal connections of respective modules. If the power and signal wire connections are OK, then the respective modules may be faulty. Replace the fault modules and return it to the factory for repair.

Uplink / downlink power low alarm

Eliminate alarm by correct setting of uplink/downlink power threshold The recommended power threshold is within the range of 10~40dBm. If alarm can not be cleared, check the equipment.

Field low alarm Eliminate alarm by correct setting of field threshold. The recommended field threshold is within the range of –40~-80dBm. If alarm can not be cleared, check the DT antenna system.

Oscillation alarm Check whether the Isolation between donor antenna and mobile antenna is large enough. Adjustment to RX/TX antennas can eliminate self-excited oscillation. Verify the (I) is 15dB larger than Gmax.

Uplink / downlink VSWR alarm

Check DT antenna system if there is uplink VSWR alarm. Check MT antenna system if there is downlink VSWR alarm.

Over temperature alarm Eliminate alarm by correct setting of temperature threshold. If alarm can not be cleared, apply climatic protection to the equipment

6 MAINTENANCE

The AVS BSR 933 C repeater offers trouble free operation and generally does not need maintenance. The equipment operation status can be observed remotely through OMC. Periodic inspection of the repeater equipment(s) is recommended, the recommended tasks includes:

Inspect and record operation status and output power of the repeater from OMC or RPS. Verify the direction and position of antennas. Re-align if necessary. Make sure the cable gland and sealing on the RF cable connectors are not damaged. Verify lightning and grounding protection are in good condition. For MCU Li-ion back-up battery, verify its state. Deeply discharged battery shall be return to AVS

for replacement. A simple procedure to check Li-ion battery: after operating for 24-hours, switch off AC

power supply. Measure and if the voltage of Li-on battery drops below 16V within one hour, the Li-on battery has been over-discharged.
