2. IntroductionLGP Allgon AR repeaters are used to fill out uncovered areas in cellularmobile systems, such as base station fringe areas, road tunnels, businessand industrial buildings, etc.An AR repeater receives signals from a base station, amplifies andretransmits the signals to mobile stations. Also it receives, amplifies andretransmits signals 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. As analternative to the donor antenna, the repeater can be connected to thebase station via an optic fiber cable.Control of the repeaters is performed using a desktop or notebook loadedwith the LGP Allgon OMT32, Operation and Maintenance Terminal,which can communicate with the repeaters either locally or remotely viamodem. Remote operation can be performed either via PSTN or a GSMnet.To be able to control many LGP Allgon AR repeaters in common, there isan LGP Allgon OMS, Operation and Maintenance System.The AR repeaters are described in this manual. OMT32 is described inthe OMT32, User’s Manual.Figure 2-1.  Allgon AR RepeaterLGP Allgon AB H|H#H or?¦6cro¤au
Repeater OverviewThe AR repeater family includes the following main repeater types:•Channel selective GSM repeater.•Channel selective CDMA/WCDMA repeater.•Channel selective high power CDMA/WCDMA repeater.•Band selective repeater.•Combined repeater.•BMU, Base station Master Unit.•RMU, Repeater Master Unit.•FOR, Fiber Optic Repeater.These main repeater types are briefly described below.In this document, 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 repeater This repeater is used for channel selective systems such as GSM, DCS,PCN and PCS.The channel selective GSM repeater has an RF port for a donor antenna(or RF cable) and an RF port for a service antenna (or RF cable).Channel selective CDMA/WCDMA repeaters These repeater types are used for digital code division systems inaccordance with IS-95 or J-std-008 standard, and wideband digital codedivision systems.The channel selective CDMA/WCDMA repeaters have an RF port for adonor antenna (or RF cable) and an RF port for a service antenna (or RFcable).Channel selective high power CDMA/WCDMA repeaters These are CDMA/WCDMA repeaters equipped with a 6dB (typically) BA(Booster Amplifier) in the downlink transmitting signal path.The channel selective high power CDMA/WCDMA repeaters have an RFport for a donor antenna (or RF cable) and an high power RF port for aservice antenna (or RF cable).

Band selective repeater This repeater type is used for analog or digital systems such as NMT,GSM, TACS, ETACS, AMPS, DAMPS, CDMA and WCDMA.The band selective repeater has an RF port for a donor antenna (or RFcable) and an RF port for a service antenna (or RF cable).Combined repeaterSome of the repeater types can be combined in the same repeater chassisand be in operation in parallel.The combined repeater has normally two RF ports for donor antennas (orRF cables) and two RF ports for service antennas (or RF cables).BMU, Base Station Master Unit A BMU is one of the RF repeater types equipped with a FOU (Fiber OpticUnit) that makes the repeater receive and transmit optic signals on theservice side.The BMU has an RF port for BTS connection and up to four fiber opticports that can be connected to FORs.RMU, Repeater Master Unit An RMU is one of the RF repeater types equipped with a FOU (FiberOptic Unit) that makes the repeater receive and transmit optic signals onthe service side.The RMU has an RF port for a donor antenna and up to four fiber opticports that can be connected to FORs.FOR, Fiber Optic Repeater A FOR is one of the RF repeater types equipped with a FOU that makesthe repeater receive and transmit optic signals on the donor side.The FOR has a fiber optic donor port and an RF port for a serviceantenna (or RF cable). By equipping a FOR with a splitter, another FORcan be connected in serial.This unit can be connected to a BMU, RMU or FOR (with splitter).

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 LGP Allgon repeater, which can be installed with aminimum of investments, is a better solution. You save installation costsas 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.or?¦6cro H|H#H LGP Allgon AB¤aV
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 mast usedfor other purposes is available for a repeater installation. The mast heightis 42 meter and it is located on a hill. The scenario is illustrated inFigure 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.

Sports Arena A 2000 spectators sports arena with metallic roof had an indoor signalstrength too low to provide a fair service in most parts of the arena. Thenearest base station was 8 kilometers away and it was equipped with onecarrier only.A donor antenna directed towards the base station was mounted on amast outside the building and a repeater was installed inside the buildingwith the service antenna on the arch vault.

3. InstallationBefore installation, read carefully Chapter 1, Safety.Siting the RepeaterLGP Allgon repeaters are designed for outdoor usage. However, humidityand temperature changes may have affect on the reliability. A preferablesite for 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 LGP Allgon repeaters are designed with a weather proof outdoor case thatcan be 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.LGP Allgon can provide a shelter designed for these repeaters. Thisshelter is shown in Figure 3-1.Outdoor Installation and Service Limitations Sited outdoors, the repeater must not be opened for installation or serviceat bad weather, such as:–Intense rainfall, snowfall or hail.–Storm or high wind.–Extremely low or high temperature.–High humidity of the air.LGP Allgon AB H|H#H o#ff#croau

5. Functional DescriptionThis chapter contains a short general description. After that you will finddescriptions of the various repeater types on a unit level, includingrepeater types, design, block diagrams, board and sub unit descriptions,connection ports, and cabling.General DescriptionLGP Allgon AR 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 can be connected to a BS donor antenna, directed towardsthe base station, and to an MS service antenna directed towards the areato be covered. These antennas are connected to the repeater with N typemale connectors.The repeaters can also be connected via RF cables or fiber optic cablesinstead of donor or service antennas.To prevent instability due to poor antenna isolation, a built-in antennaisolation supervision feature reduces the gain level automatically whenpoor antenna isolation is detected. For channel selective CDMA repeaters,poor antenna isolation is detected and managed by means of an MRX unit(Measurement Receiver).The LGP Allgon repeaters are controlled by powerful microprocessors.Alarm and operational status 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 LGP Allgon OMT32, whichcommunicate, locally or remotely via modem, with the repeater.

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 be either a lowcover or a high cover. The latter consists of another cabinet which can beused as an empty cover or be equipped as a part of the repeater or as anindependent repeater unit.Inside the repeater, a number of amplifier boards are individually shieldedand located under a metal cover that can be folded out. These amplifierboards are of different types depending on the supported system.A repeater with a high cover that is equipped as two independent repeaterunits (Combi) can, for example, be equipped for channel selectiveoperation in the cabinet and band selective operation in the cover.Functionally, all the repeater types are built up with a number of subunits. These are listed below and pointed out in the following sections.Sub Unit OverviewThe main repeater sub units are:CHA, Channel Amplifier boardChannel 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, CDMA/WCDMA Segment Amplifier board Channel selective CDMA/WCDMA repeaters can handle two CDMA orWCDMA repeater channels. For every even number of repeater channels,two CSA amplifier boards and two PA amplifier boards are required inthe repeater, one pair of CSA/PA boards for uplink signaling and one pairfor downlink signaling. Each repeater channel is allocated to a radiochannel or switched off.BSA, Band selective amplifier board Band selective repeaters can handle multi-carriers over a wide band. Thebandwidth is adjustable. A band selective repeater channel requires twoBSA boards and two PA amplifier boards in the repeater. One pair ofBSA/PA boards for uplink signaling and one pair for downlink signaling.¦o6cro#fH6c|cro H|H#H LGP Allgon ABSaV

Antenna isolationThe MRX unit automatically supervises the antenna isolation. The systemwill detect both the margins to instability and full self-oscillation.Two different alarm types (Warning and Ceasing) can be sent by theMRX unit due to poor antenna isolation:–If a low margin to instability is detected, then a Warning alarm issent and the gain is reduced gradually to a preset value.–If the MRX unit detects self-oscillation, then a Warning alarm is sentand the gain is reduced to the same preset value.–When the MRX unit no longer senses any isolation problems aCeasing signal is sent and the gain is increased to the level set by theoperator.Return loss (VSWR)The MRX unit will automatically and continuously supervise both thedonor and the service antennas. The operator can, however, also manuallystart a measurement of a desired antenna simply by selecting a CDMAantenna, which will then be used for the measurement.A Warning alarm is sent when the return loss is below an alarmthreshold that is set by the operator. When the return loss is above thesame threshold again, a Ceasing signal is sent.Spectrum monitoringThis feature allows the operator to perform spectrum analyzis in local orremote mode.
