P1D 2000-05 VD203 67/EN - User’s Manual ALLGON Systems AB ALR Compact Repeater Safety 1. Safety Any personnel involved in installation, operation or service of Allgon repeaters must understand and obey the following: • Allgon repeaters are designed to receive and amplify signals from one or more base stations and retransmit the signals to one or more mobile stations. Also, the repeaters are designed to receive signals from one or more mobile stations, amplify and retransmit to the base stations. The repeaters must be used exclusively for these purposes and nothing else. • Repeaters supplied from the mains must be connected to grounded outlets and in conformity with any local regulations. • The power supply unit contains dangerous voltage that can cause electric 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 while the mains is connected. • The repeater cover must be secured in opened position, e.g. by tying it up, at outdoor repeater work. Otherwise, the cover can be closed by the wind 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, be careful not to drop parts or the entire repeater. Falling parts can cause serious personal injury. • Any repeater, including this repeater, will generate radio signals and thereby give rise to electromagnetic fields that may be hazardous to the health of any person who is extensively exposed to the signals at the immediate proximity of the repeater and the repeater antennas. • The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene, HYDROGEN FLUORIDE that gives off small amounts of hydrogen fluoride when heated. Hydrogen fluoride is poisonous. Do not use heating tools when stripping off coaxial cable insulation. No particular measures are to be taken in case of fire because the emitted concentration of hydrogen fluoride is very low. • A lithium battery is permanently mounted on the repeater board. Due to the risk of explosion, this battery must only be removed from the board by an authorized service technician. VD203 67/EN - User’s Manual Rev. P1D 2000-05 1-1 Safety ALR Compact Repeater ALLGON Systems AB Static Electricity Static electricity means no risk of personal injury but it can severely damage essential parts of the repeater, if not handled carefully. Parts on the printed circuit board as well as other parts in the repeater are sensitive to electrostatic discharge. Never touch the printed circuit board or uninsulated conductor surfaces unless absolutely necessary. If you must handle the printed circuit board or uninsulated conductor surfaces, use ESD protective equipment, or first touch the repeater chassis with your hand and then do not move your feet on the floor. Never let your clothes touch printed circuit boards or uninsulated conductor surfaces. Always store printed circuit boards in ESD-safe bags. 1-2 Rev. P1D 2000-05 VD203 67/EN - User’s Manual ALLGON Systems AB ALR Compact Repeater Introduction 2. Introduction Figure 2-1. Allgon ALR Compact Repeater Allgon repeaters are used to fill out uncovered areas in cellular mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc. A repeater receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a service antenna directed towards the area to be covered. Control of the repeaters is performed using a desktop or notebook loaded with the Allgon OMT32, Operation and Maintenance Terminal, which can communicate with the repeaters, either locally or remotely via modem. Remote operation can be performed either via a traditional telephone line or via a mobile phone that can be installed inside the repeater. To be able to control many Allgon AR repeaters in common, there is an Allgon OMS, Operation and Maintenance System. The compact repeater is described in this manual. OMT32 is described in the AR Repeaters and OMT32, User’s Manual. OMS is described in the Advanced Repeater OMS, User’s Manual. VD203 67/EN - User’s Manual Rev. P1D 2000-05 2-1 Introduction ALR Compact Repeater ALLGON Systems AB Repeater Types The following repeater types are available: • Band selective repeater with adjustable bandwidth • Combined repeater Band selective repeater with adjustable bandwidth The band selective compact repeater has filters that can be set to various bandwidths. This repeater type is used for analog or digital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA. Combined repeater Two separate band selective repeater units for different bandwidths or systems can be combined in the same repeater chassis and be in operation in parallel. 2-2 Rev. P1D 2000-05 VD203 67/EN - User’s Manual ALLGON Systems AB ALR Compact Repeater Introduction Using Repeaters In areas where the radio signal propagation is poor repeaters can be used to 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 walls Other examples where repeaters can be used to increase the coverage are: – Shaded areas – Fringe coverage areas In areas where the traffic intensity is low, it is not cost efficient to install a base station. An Allgon repeater, which can be installed with a minimum of investments, is a much better solution. You save installation costs as well as operational costs. Examples of using repeaters Two examples are described in the following sections. An outdoor example in a shaded valley and an indoor example in a sports arena. VD203 67/EN - User’s Manual Rev. P1D 2000-05 2-3 Introduction ALR Compact Repeater ALLGON Systems AB Shaded Area A valley is shaded by hills. There is a base station 5 kilometers away, but the lowest signal strength in the valley is less than –100dBm. A mast used for other purposes is available for a repeater installation. The mast height is 42 meter and it is located on a hill. The scenario is illustrated in Figure 2-2. Donor antenna Service antenna Figure 2-2. Repeater coverage of shaded area The donor antenna of the repeater was mounted at the top of the mast and the service antenna was mounted at the half mast. The antenna isolation was measured to over 100dB. The repeater was set to max. 80dB gain. Measured levels: Received signal level Donor antenna gain Cable loss Repeater input level – 60.0 15.0 – 5.0 – 50.0 Adjusted repeater gain Repeater output level dBm dBi dB dBm 70.0 dB 20.0 dBm Cable loss Service antenna gain Radiated output level – 5.0 dB 8.0 dBi 23.0 dBm The measured result in the valley was better than –90dBm. 2-4 Rev. P1D 2000-05 VD203 67/EN - User’s Manual ALLGON Systems AB ALR Compact Repeater Introduction Sports Arena A 2000 spectators sports arena with metallic roof had an indoor signal strength too low to provide a fair service in most parts of the arena. The nearest base station was 8 kilometers away and it was equipped with one carrier only. A donor antenna directed towards the base station was mounted on a mast outside the building and a repeater was installed inside the building with the service antenna on the arch vault. The scenario is illustrated in Figure 2-3. Donor antenna Service antenna Figure 2-3. Repeater in sports arena The antenna isolation was measured to over 85dB. Measured levels: Received signal level Donor antenna gain Cable loss Repeater input level Adjusted repeater gain Repeater output level Cable loss Service antenna gain Radiated output level – 80.0 15.0 – 5.0 – 70.0 dBm dBi dB dBm 70.0 dB 0.0 dBm – 2.0 dB 7.0 dBi 5.0 dBm The signal strength was fair for service in the entire arena.

Siting the Repeater Allgon repeaters are designed for outdoor usage. However, humidity and temperature changes may have affect on the reliability. A preferable site 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 is essential that the air can circulate around the repeater with no obstacle. The operating temperature must not exceed +55°C. A shelter can be used to shade the repeater from direct sunshine. Shelter Allgon repeaters are designed with a weather proof outdoor case that can 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 hailing there must be some kind of permanent or temporary shelter. This is applicable to gentle rainfall, snowfall or hail. Limitations for very bad weather is found in the next section. Outdoor Installation and Service Limitations Sited outdoors, the repeater must not be opened for installation or service at bad weather, such as: – – – – VD203 67/EN - User’s Manual Intense rainfall, snowfall or hail Storm or high wind Extremely low or high temperature High humidity of the air Rev.

P1D 2000-05 VD203 67/EN - User’s Manual ALLGON Systems AB ALR Compact Repeater Functional Description 5. Functional Description and Design Allgon repeaters work as bi-directional on-frequency amplifiers. A repeater receives, amplifies, and retransmits signals downlink and uplink simultaneously, i.e. from the base station via the repeater to the mobile stations and from the mobile stations via the repeater to the base station. The repeater is connected to a BS antenna, directed towards the base station, and to a MS antenna directed towards the area to be covered. These antennas are connected to the repeater with N type male connectors. To prevent instability due to poor antenna isolation, a built-in antenna isolation supervision feature reduces the gain level automatically when poor 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 a desktop or notebook and the Allgon OMT32, which communicate, locally or remotely via modem, with the repeater. Remote operation is performed using a telephone line or a built-in mobile phone equipped with a data interface. VD203 67/EN - User’s Manual Rev. P1D 2000-05 5-1 Functional Description ALR Compact Repeater ALLGON Systems AB 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 for outdoor use as well as indoor use. The chassis consists of a cabinet and a cover joined with hinges. The cabinet contains the repeater circuitry. The cover can either be a thin cover or a large cover. The latter consists of another cabinet which can be 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 band selective operation with adjustable bandwidth. A combined repeater can be equipped for different bandwidths or different systems. Both the uplink and downlink circuitry is built up on a single BSC board inside the repeater. The various amplifiers and RF modules are individually shielded by metal covers. The BSC band selective compact repeater board The band selective compact repeater board can handle one wide band repeater channel, uplink and downlink. The band width is adjustable. Other units In addition to the BSC repeater board, the repeater contains: • DPX Duplex filter, located on the upper part of the repeater. • CMB Combiner unit, located on the RCC unit in repeaters with an RCC unit that works in the same system as the repeater. • RCC unit (optional), see Chapter 6, Optionals.

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 and AMPS/DAMPS systems. Downlink signal path The signal from the base station is received via the repeater BS antenna and is forwarded through a combiner (CMB) to the ANT input of a duplex filter (DPX). The signal from the LO output of the duplex filter is, via the P126 port, fed to the BSC board. On the BSC board, the signal is amplified in a low noise amplifier (LNA) and is then entered the band selective amplifier circuitry. The first mixer stage in the BSC amplifier, which is controlled by a synthesizer, converts the received frequency down to the IF frequency. The signal is then filtered by a SAW bandpass filter and, not shown in the 5-6 Rev. P1D 2000-05 VD203 67/EN - User’s Manual ALLGON Systems AB ALR Compact Repeater Functional Description figure, amplified before it is fed to the second mixer stage, controlled by the same synthesizer as the previous one, for converting back to the original frequency. The SAW filter is adjustable and can be software changed from within OMT32 (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 poor antenna isolation. A detector in the PA stage measures continuously the output level. The signal from this detector is used by the automatic gain control, AGC, to supervise and, if necessary, reduce the output power to keep it under a maximum level. The AGC gain control affects all the amplification stages. The output signal from the BSC board is taken from the P128 port and it is fed to the HI port of a duplex filter (DPX). The output signal from the ANT port of the duplex filter is fed to the repeater MS antenna. RCC The optional RCC Remote Communication Control unit is located inside the repeater, see Figure 5-1 on page 5-3. Communication with the base station is performed by means of a built-in mobile feature that has the antenna connected to the BS combiner (CMB). Data is transferred between the repeater CU and the built-in mobile feature via the P130 port. The RCC unit is powered via the P130 port and the unit has a battery with capacity to send a number of alarms if a mains power failure occurs. R2R The Repeater to Repeater Link feature makes it possible to communicate with a number of repeaters via one RCC unit in one of the repeaters in an R2R 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 the P124 port. The R2R feature is further described on page 5-18.
