1. Safety Any personnel involved in installation, operation or service of Allgonrepeaters must understand and obey the following:•Allgon repeaters are designed to receive and amplify signals from one ormore base stations and retransmit the signals to one or more mobilestations. Also, the repeaters are designed to receive signals from one ormore mobile stations, amplify and retransmit to the base stations. Therepeaters must be used exclusively for these purposes and nothing else.•Repeaters supplied from the mains must be connected to groundedoutlets and in conformity with any local regulations.•The power supply unit in repeaters supplied from the mains containsdangerous voltage that can cause electric shock. Disconnect the mainsprior to any work in such a repeater. Any local regulations are to befollowed when servicing repeaters.Authorized service personnel only are allowed to service repeaters whilethe mains is connected.•The repeater cover must be secured in opened position, e.g. by tying itup, at outdoor repeater work. Otherwise, the cover can be closed by thewind and cause your fingers getting pinched or your head being hit.•When working on a repeater on high ground, e.g. on a mast or pole, becareful not to drop parts or the entire repeater. Falling parts can causeserious personal injury.•Any repeater, including this repeater, will generate radio signals andthereby give rise to electromagnetic fields that may be hazardous to thehealth of any person who is extensively exposed to the signals at theimmediate proximity of the repeater and the repeater antennas.BERYLLIUM OXIDE•The CHA channel board power transistors, the PA amplifier boardpower transistors, and the combiners (CMB) contain beryllium oxide(BeO) that is poisonous if present as dust or smoke which can beinhaled. The power transistors mentioned are mounted with twoscrews as opposed to other transistors.Do not file, grind, machine, or treat these parts with acid.Warning signs are applied on boards and units that contain berylliumoxide. These warning signs are shown in the next section.HYDROGEN FLUORIDE•The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene,that gives off small amounts of hydrogen fluoride when heated.Hydrogen fluoride is poisonous. Do not use heating tools whenstripping off coaxial cable insulation.No particular measures are to be taken in case of fire because theemitted concentration of hydrogen fluoride is very low.Allgon Systems AB AR Repeaters SafetyVD203 66/EN - User’s Manual Rev.

2. Introduction Allgon repeaters are used to fill out uncovered areas in cellular mobilesystems, such as base station fringe areas, road tunnels, business andindustrial buildings, etc.A repeater receives signals from a base station, amplifies and retransmitsthe signals to mobile stations. Also it receives, amplifies and retransmitssignals in the opposite direction. Both directions are servedsimultaneously.To be able to receive and transmit signals in both directions, the repeateris connected to a donor antenna directed towards the base station and toa service antenna directed towards the area to be covered.Control of the repeaters is performed using a desktop or notebook loadedwith the Allgon OMT32, Operation and Maintenance Terminal, which cancommunicate with the repeaters, either locally or remotely via modem.Remote operation can be performed either via a traditional telephone lineor via a mobile phone that can be installed inside the repeater.To be able to control many Allgon AR repeaters in common, there is anAllgon OMS, Operation and Maintenance System.The repeaters and the OMT32 is described in this manual. The OMS isdescribed in the OMT32, User’s Manual.Figure 2-1. Allgon AR RepeaterAllgon Systems AB AR Repeaters IntroductionUser’s Manual VD203 66/EN Rev. P1A 2000-09 2 - 1
Repeater Types The following repeater types are currently available:•Channel selective GSM repeater•Channel selective CDMA repeater•Channel selective high power CDMA repeater•Band selective repeater with fixed bandwidth•Band selective repeater with adjustable bandwidth•Combined repeaterIn the OMT32, the channel selective 900, 1800, and 1900 systems arecalled GSM, DCS and PCS respectively, even though these systems mayhave different names in other parts of the world.Channel selective GSM repeaterA channel selective GSM repeater can be equipped with two, four, six oreight channels. This repeater type is used for channel selective systems,such as GSM, DCS, PCN and GSM 1900 (PCS).Channel selective CDMA repeaterA channel selective CDMA repeater can be equipped with one or twochannels. This repeater type is used for digital code division systems inaccordance with IS-95 or J-std-008 standard.Channel selective high power CDMA repeaterA channel selective CDMA repeater like the previous one, but equippedwith a 6dB (typically) BA (Booster Amplifier) unit.Band selective repeater with fixed bandwidthA band selective repeater with fixed bandwidth has fixed filters for acertain bandwidth. This repeater type is used for analog or digitalsystems, such as NMT, GSM, TACS, ETACS, AMPS, DAMPS and CDMA.Band selective repeater with adjustable bandwidthA band selective repeater with adjustable bandwidth has filters that canbe set to various bandwidths. This repeater type is used for analog ordigital systems, such as NMT, TACS, ETACS, AMPS, DAMPS and CDMA.Combined repeaterSome of the above mentioned types can be combined in the same repeaterchassis and be in operation in parallel.Introduction AR Repeaters Allgon Systems AB2 - 2 Rev.

Using RepeatersIn areas where the radio signal propagation is poor repeaters can be usedto fill out those areas which are not covered by the base station.The following scenarios are examples on this:–Sports arenas–Fair halls–Large shopping centres–Road and railway tunnels–Indoors in buildings with metal or concrete wallsOther examples where repeaters can be used to increase the coverage are:–Shaded areas–Fringe coverage areasIn areas where the traffic intensity is low, it is not cost efficient to installa base station. An Allgon repeater, which can be installed with aminimum of investments, is a much better solution. You save installationcosts as well as operational costs.Examples of using repeatersTwo examples are described in the following sections. An outdoor examplein a shaded valley and an indoor example in a sports arena.Allgon Systems AB AR Repeaters IntroductionUser’s Manual VD203 66/EN Rev. P1A 2000-09 2 - 3
Shaded Area A valley is shaded by hills. There is a base station 5 kilometers away, butthe lowest signal strength in the valley is less than –100dBm. A mastused for other purposes is available for a repeater installation. The mastheight is 42 meter and it is located on a hill. The scenario is illustratedin Figure 2-2.The donor antenna of the repeater was mounted at the top of the mastand the service antenna was mounted at the half mast. The antennaisolation was measured to over 100dB. The repeater was set to 80dB gain.Measured levels: Received signal level – 60.0 dBmDonor antenna gain 15.0 dBiCable loss –5.0 dBRepeater input level – 50.0 dBmAdjusted repeater gain 70.0 dBRepeater output level 20.0 dBmCable loss – 5.0 dBService antenna gain 8.0 dBiRadiated output level 23.0 dBmThe measured result in the valley was better than –90dBm.Donor antennaService antennaFigure 2-2.

3. InstallationBefore installation, read carefully Chapter 1, Safety.Siting the Repeater Allgon repeaters are designed for outdoor usage. However, humidity andtemperature changes may have affect on the reliability. A preferable sitefor the repeater is thus indoor, in a tempered and ventilated room.Sunshine If a repeater is placed outdoor and can be exposed to direct sunshine, it isessential that the air can circulate around the repeater with no obstacle.The operating temperature must not exceed +55°C. A shelter can be usedto shade the repeater from direct sunshine.Shelter Allgon repeaters are designed with a weather proof outdoor case that canbe mounted without any kind of shelter from rain, snow or hail.If a repeater is to be opened on the site when raining, snowing, or hailingthere must be some kind of permanent or temporary shelter. This isapplicable to gentle rainfall, snowfall or hail. Limitations for very badweather is found in the next section.Allgon can provide a shelter designed for these repeaters. This shelter isshown in Figure 3-1.Outdoor Installation and Service Limitations Sited outdoors, the repeater must not be opened for installation orservice at bad weather, such as:–Intense rainfall, snowfall or hail–Storm or high wind–Extremely low or high temperature–High humidity of the airAllgon Systems AB AR Repeaters InstallationUser’s Manual VD203 66/EN Rev.

5. Functional Description Allgon repeaters work as bi-directional on-frequency amplifiers.A repeater receives, amplifies, and retransmits signals downlink anduplink simultaneously, i.e. from the base station via the repeater to themobile stations and from the mobile stations via the repeater to the basestation.The repeater is connected to a BS antenna, directed towards the basestation, and to a MS antenna directed towards the area to be covered.These antennas are connected to the repeater with N type maleconnectors.To prevent instability due to poor antenna isolation, a built-in antennaisolation supervision feature reduces the gain level automatically whenpoor antenna isolation is detected.The Allgon repeaters are controlled by powerful microprocessors.Alarm and operational LEDs are visible on the repeater front.The repeater works with convection cooling without fan.Operational parameters such as gain, channel number, power levels, etc.are set using a desktop or notebook and the Allgon OMT32, whichcommunicate, locally or remotely via modem, with the repeater. Remoteoperation is performed using a telephone line or a built-in mobile phoneequipped with a data interface.ALLGON System AB AR Repeaters Functional DescriptionUser’s Manual VD203 66/EN Rev.

Repeater Design The repeater is housed in a cast aluminium chassis that is waterproof,class NEMA4/IP65, for outdoor use. The chassis has a design suited foroutdoor use as well as indoor use.The chassis consists of a cabinet and a cover joined with hinges. Thecabinet contains the repeater circuitry. The cover can either be a thincover or a large cover. The latter consists of another cabinet which canbe used as an empty cover or be equipped as an independent repeater unit.The cover has two external LEDs for operation and alarm indication.The cabinet as well as a large cover can be equipped for channel selectiveoperation or band selective operation. A combined repeater is normallyequipped for channel selective operation in the cabinet and band selectiveoperation in the cover.Different amplifier boards are used to get the various operations (seebelow). The amplifier boards are individually shielded and located undermetal cover sheets which can be folded out.CHA, Channel selective GSM amplifier boardChannel selective GSM repeaters can handle up to eight repeater channels(four if the CU part number is K103/1). For every even number ofrepeater channels, two CHA amplifier boards are required in the repeater,one CHA board for uplink signaling and one board for downlink signaling.Each repeater channel is allocated to a radio channel or switched off. In aGSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), onerepeater channel can handle eight calls (sixteen if half-rate encoding isused).CSA, Channel selective CDMA amplifier boardCurrent CDMA repeaters can handle two CDMA repeater channels. Forevery even number of repeater channels, two CSA amplifier boards andtwo PA amplifier boards are required in the repeater, one pair of CSA/PAboards for uplink signaling and one pair for downlink signaling. Eachrepeater channel is allocated to a radio channel or switched off.BSA, Band selective amplifier boardBand selective repeaters can handle one wide band repeater channel. Theband width is either fixed or adjustable (fixed for 900MHz repeaters only).A band selective repeater channel requires two BSA boards and two PAamplifier boards in the repeater. One pair of BSA/PA boards for uplinksignaling and one pair for downlink signaling.BA, High power CDMA booster amplifier boardCDMA repeaters can be equipped with a high power booster amplifierboard that boosts the output gain with typically 6dB. A high powerCDMA repeater can operate with maximum 2 channels.Functional Description AR Repeaters ALLGON System AB5 - 2 Rev. P1A 2000-09 User’s Manual VD203 66/EN

Thisdiagram is applicable to repeaters for e.g. NMT, TACS, ETACS, AMPS,DAMPS and CDMA systems.Downlink signal pathThe signal from the base station is received via the repeater BS antennaand is then forwarded through a directional coupler (DC). The signalpasses a duplex filter (DPX), is amplified in a low noise amplifier (LNA),and enters the band selective amplifier board (BSA).DCBSP32P31 P33TEST -30 dBDCMSTEST -30 dBBSA - DLPA - DLLNA - DLMS -20 dB PA - ULBSA - UL LNA - ULDPXMSDPXBSALIRIA P34CUALLGONALLGONALLALLRCUP27PSU ALIANT OUT ANT HILOANTOUTANTHILOIN OUT1 P101 P301P4 P5ININOUT1P301 P101P4P5MSCBANDSELECTIVEREPEATERBS antennaBase stationTelephonelineModemModemBatteryExternal alarm sensorsMS antennaR2R netFigure 5-8.

The first mixer stage on the BSA amplifier board, which is controlled by asynthesizer, converts the received frequency down to the IF frequency.The signal is then filtered by SAW bandpass filters and, not shown in thefigure, amplified before it is fed to the second mixer stage for conversionback to the original frequency. The SAW filter can be either fixed or adjustable depending on the BSAboard used. If the BSA board has fixed band width, this SAW filter isfixed and selected for the current band width. If the BSA board hasadjustable band width, the SAW filter combination can be softwarechanged from within OMT32 (or OMS) to cover various band widths.The following power amplifier is controlled by the CU. The amplifier gainwill be reduced to avoid instability due to poor antenna isolation.A detector on the PA board measures continuously the output level. Thesignal from this detector is used by the automatic gain control, AGC, tosupervise and, if necessary, reduce the output power to keep it under amaximum level. The AGC gain control affects several of the amplificationstages.The output signal passes duplex filter (DPX) and a directional coupler(DC) before it is fed to the repeater MS antenna.RCU The optional RCU Remote Communication Unit is located inside therepeater (described in Chapter 6, Optionals).Communication with the base station is performed by means of a built-inmobile feature that has the antenna connected to the BS directionalcoupler (DC). Data is transferred between the repeater and the built-inRCU unit via the P32 modem port.The RCU unit is powered via the P27 auxiliary port and the unit has abattery with capacity to send a number of alarms if a mains power failureoccurs.R2R The Repeater to Repeater Link feature makes it possible to communicatewith a number of repeaters via one RCU unit in one of the repeaters inan R2R net. Several RCU units can also be used in the same net.The repeaters in the R2R net are connected to the P34 port.The R2R feature is described in Chapter 6, Optionals.ALLGON System AB AR Repeaters Functional DescriptionUser’s Manual VD203 66/EN Rev.

OMS, Operation and Maintenance System The OMS, Operation and Maintenance System is an Allgon softwarepackage for controlling a large repeater fleet by using computers withWindows NT in networks with a common database.The OMS is capable of operating a large number of repeaters. Multiplemodems can be used for several incoming and outgoing parallel activities,such as polling, radio parameter configuration, software downloading, etc.OMS is an improved OMC, Operation and Maintenance Center. The latteris replaced by the OMS and is no longer subject to further development.Traffic Statistics Traffic statistics is available for channel selective GSM 900, GSM 1900and DCS/PCN 1800 repeaters, provided that the repeaters have the latestCU software versions, the latest CU and CHA boards, and that an OMS isused to poll and view the statistics.Battery Backup Battery backup can be arranged by completing the repeater with anAllgon UPS (Uninterruptible Power Supply). The Allgon UPS has anexterior similar to the repeater which means that it can preferably bemounted adjacent to the repeater.Fiber Optic Interface A Fiber Optic Interface that includes transmitter, receiver, alarm boardand power supply is available for all the Allgon repeaters. The fiber opticinterface can be adapted for separate uplink and downlink fiber as well asfor bi-directional one-fiber distribution.7/16" Antenna Cable Connectors A 7/16" antenna cable kit is available for all the Allgon repeaters. This kitincludes 7/16" antenna connectors for uplink and downlink antennasmounted on two repeater cable inlet flanges, and cables and connectorsfor connection to the DC directional couplers inside the repeater.Optionals AR Repeaters Allgon Systems AB6 - 8 Rev.
