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 contains dangerous voltage that can causeelectric shock. Disconnect the mains prior to any work in the repeater.Any local regulations are to be followed 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.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.•A lithium battery is permanently mounted on the repeater board. Dueto the risk of explosion, this battery must only be removed from theboard by an authorized service technician.ALLGON Systems AB ALR Compact Repeater SafetyVD203 67/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 compact repeater is described in this manual. OMT32 is described inthe AR Repeaters and OMT32, User’s Manual. OMS is described in theAdvanced Repeater OMS, User’s Manual.Figure 2-1.

Repeater Types The following repeater types are available:•Band selective repeater with adjustable bandwidth•Combined repeaterBand selective repeater with adjustable bandwidthThe band selective compact repeater has filters that can be set to variousbandwidths. This repeater type is used for analog or digital systems, suchas NMT, TACS/ETACS, AMPS, DAMPS and CDMA.Combined repeaterTwo separate band selective repeater units for different bandwidths orsystems can be combined in the same repeater chassis and be in operationin parallel.Introduction ALR Compact Repeater ALLGON Systems AB2 - 2 Rev. P1D 2000-05 VD203 67/EN - User’s Manual
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 outdoorexample in a shaded valley and an indoor example in a sports arena.ALLGON Systems AB ALR Compact Repeater IntroductionVD203 67/EN - User’s Manual Rev. P1D 2000-05 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 max.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.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 ALR Compact Repeater InstallationVD203 67/EN - User’s Manual Rev.

5. Functional Description and Design 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, power levels, etc. are set using adesktop or notebook and the Allgon OMT32, which communicate, locallyor remotely via modem, with the repeater. Remote operation isperformed using a telephone line or a built-in mobile phone equipped witha data interface.ALLGON Systems AB ALR Compact Repeater Functional DescriptionVD203 67/EN - User’s Manual Rev.

Band Selective Compact Repeater Block Diagram Figure 5-3 shows a block diagram of the band selective compact repeater.This diagram is applicable to repeaters for e.g. NMT, TACS/ETACS andAMPS/DAMPS systems.Downlink signal pathThe signal from the base station is received via the repeater BS antennaand is forwarded through a combiner (CMB) to the ANT input of a duplexfilter (DPX). The signal from the LO output of the duplex filter is, viathe P126 port, fed to the BSC board. On the BSC board, the signal isamplified in a low noise amplifier (LNA) and is then entered the bandselective amplifier circuitry.The first mixer stage in the BSC amplifier, which is controlled by asynthesizer, converts the received frequency down to the IF frequency.The signal is then filtered by a SAW bandpass filter and, not shown in theRCCBSC - ULPA LNAP121 P122BSC - DL PALNAP126 P128P130P112 P119P130DPXMSP118BSC - CUP124CMBBSANT HILO HILO ANTDPXBSMSC PSMBAND SELECTIVE COMPACT REPEATERBSantennaBase stationTelephone lineModemModemBatteryExternal alarm sensorsMSantennaFigure 5-3.

figure, amplified before it is fed to the second mixer stage, controlled bythe same synthesizer as the previous one, for converting back to theoriginal frequency.The SAW filter is adjustable and can be software changed from withinOMT32 (or OMS) to cover various band widths. The following power amplifier (PA) is controlled by the Control Unit(CU). The output gain can be reduced to avoid instability due to poorantenna isolation. A detector in the PA stage 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 all the amplification stages. The output signal from the BSC board is taken from the P128 port and itis fed to the HI port of a duplex filter (DPX). The output signal from theANT port of the duplex filter is fed to the repeater MS antenna.RCCThe optional RCC Remote Communication Control unit is located insidethe repeater, see Figure 5-1 on page 5-3.Communication with the base station is performed by means of a built-inmobile feature that has the antenna connected to the BS combiner(CMB). Data is transferred between the repeater CU and the built-inmobile feature via the P130 port.The RCC unit is powered via the P130 port and the unit has a batterywith capacity to send a number of alarms if a mains power failure occurs.R2RThe Repeater to Repeater Link feature makes it possible to communicatewith a number of repeaters via one RCC unit in one of the repeaters in anR2R net. Several RCC units can be used in the same net.The repeaters in the R2R net are connected to the P118 port and to theP124 port.The R2R feature is further described on page 5-18.ALLGON Systems AB ALR Compact Repeater Functional DescriptionVD203 67/EN - User’s Manual Rev.
