P1A 2000-09 VD203 66/EN - User’s Manual Allgon Systems AB AR Repeaters 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 in repeaters supplied from the mains contains dangerous voltage that can cause electric shock. Disconnect the mains prior to any work in such a 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 CHA channel board power transistors, the PA amplifier board BERYLLIUM OXIDE power transistors, and the combiners (CMB) contain beryllium oxide (BeO) that is poisonous if present as dust or smoke which can be inhaled. The power transistors mentioned are mounted with two screws 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 beryllium oxide. These warning signs are shown in the next section. • 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. VD203 66/EN - User’s Manual Rev. P1A 2000-09 1-1 Safety AR Repeaters Allgon Systems AB • A lithium battery is permanently mounted on the CU board. Due to the risk of explosion, this battery must not be removed from the board. In case of battery malfunction, replace the CU board. The old CU board can be sent to Allgon for repair. • The heat sink element on the CDMA High Power repeater can be very hot. Do not touch this surface during operation. Warning Signs The following warning signs must be observed and be kept clean and readable. Beryllium oxide This warning sign is applied on boards and units which contain beryllium oxide parts. Beryllium oxide hazard BERYLLIUM OXIDE (Toxic) used in equipment see instruction book This warning sign is applied at the bottom, inside the cabinet, below the power supply unit. The previous section details parts containing beryllium oxide and how to avoid dangerous dealing with these parts. 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 boards as well as other parts in the repeater are sensitive to electrostatic discharge. Never touch the printed circuit boards or uninsulated conductor surfaces unless absolutely necessary. If you must handle the printed circuit boards 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. P1A 2000-09 VD203 66/EN - User’s Manual Allgon Systems AB AR Repeaters Introduction 2. Introduction Figure 2-1. Allgon AR 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 repeaters and the OMT32 is described in this manual. The OMS is described in the OMT32, User’s Manual. User’s Manual VD203 66/EN Rev. P1A 2000-09 2-1 Introduction AR Repeaters Allgon Systems AB 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 repeater In the OMT32, the channel selective 900, 1800, and 1900 systems are called GSM, DCS and PCS respectively, even though these systems may have different names in other parts of the world. Channel selective GSM repeater A channel selective GSM repeater can be equipped with two, four, six or eight channels. This repeater type is used for channel selective systems, such as GSM, DCS, PCN and GSM 1900 (PCS). Channel selective CDMA repeater A channel selective CDMA repeater can be equipped with one or two channels. This repeater type is used for digital code division systems in accordance with IS-95 or J-std-008 standard. Channel selective high power CDMA repeater A channel selective CDMA repeater like the previous one, but equipped with a 6dB (typically) BA (Booster Amplifier) unit. Band selective repeater with fixed bandwidth A band selective repeater with fixed bandwidth has fixed filters for a certain bandwidth. This repeater type is used for analog or digital systems, such as NMT, GSM, TACS, ETACS, AMPS, DAMPS and CDMA. Band selective repeater with adjustable bandwidth A band selective repeater with adjustable bandwidth 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 Some of the above mentioned types can be combined in the same repeater chassis and be in operation in parallel. 2-2 Rev. P1A 2000-09 User’s Manual VD203 66/EN Allgon Systems AB AR Repeaters 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. User’s Manual VD203 66/EN Rev. P1A 2000-09 2-3 Introduction AR Repeaters 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 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. P1A 2000-09 User’s Manual VD203 66/EN Allgon Systems AB AR Repeaters 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 75.0 dB 5.0 dBm – 2.0 dB 7.0 dBi 10.0 dBm The signal strength was fair for service in the entire arena. User’s Manual VD203 66/EN Rev. P1A 2000-09 2-5 Allgon Systems AB AR Repeaters Installation 3. Installation Before installation, read carefully Chapter 1, Safety. 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. Allgon can provide a shelter designed for these repeaters. This shelter is shown in Figure 3-1. Outdoor Installation and Service Limitations Sited outdoors, the repeater must not be opened for installation or service at bad weather, such as: – – – – User’s Manual VD203 66/EN Intense rainfall, snowfall or hail Storm or high wind Extremely low or high temperature High humidity of the air Rev.

P1A 2000-09 4-3 Commissioning AR Repeaters Allgon Systems AB Measuring the Output Power Level Uplink and downlink output power test ports are found on the directional couplers (DC) at the MS and BS antenna connectors. These test ports are marked TEST –30dB (see Figure 4-1) and are intended for measuring using e.g. a spectrum analyzer. The coupling is –30dB approximately. There is no directivity in these test ports, i.e. both uplink and downlink signal can be measured. Voltage Supply Testpoints A number of voltage supply testpoints are available in the repeater. These testpoints are named U7A - U7F for the 7V supply voltages and U26 for 26V, 13V or 10V supply voltage (depending on the repeater type). A standard multi-meter can be used on these testpoints. The testpoints are found on the DIA board in the repeater cabinet. The testpoint positions on the DIA board is detailed in the Board and Unit Descriptions section in Chapter 5. If the repeater is equipped with a second PSU, e.g. for combined channel/band selective operation, the same set of testpoints are also found on the cover DIA board. Repeater Configuration The repeater is now ready to be configured in accordance with the site conditions and system performance requirements. Pay especial attention to the antenna isolation described in the OMT32, User’s Manual. 4-4 Rev. P1A 2000-09 User’s Manual VD203 66/EN ALLGON System AB AR Repeaters Functional Description 5. Functional Description 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, channel number, 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. User’s Manual VD203 66/EN Rev. P1A 2000-09 5-1 Functional Description AR Repeaters ALLGON System 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 channel selective operation or band selective operation. A combined repeater is normally equipped for channel selective operation in the cabinet and band selective operation in the cover. Different amplifier boards are used to get the various operations (see below). The amplifier boards are individually shielded and located under metal cover sheets which can be folded out. CHA, Channel selective GSM 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 of repeater 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 a GSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), one repeater channel can handle eight calls (sixteen if half-rate encoding is used). CSA, Channel selective CDMA amplifier board Current CDMA repeaters can handle two CDMA repeater channels. For every even number of repeater channels, two CSA amplifier boards and two PA amplifier boards are required in the repeater, one pair of CSA/PA boards for uplink signaling and one pair for downlink signaling. Each repeater channel is allocated to a radio channel or switched off. BSA, Band selective amplifier board Band selective repeaters can handle one wide band repeater channel. The band width is either fixed or adjustable (fixed for 900MHz repeaters only). A band selective repeater channel requires two BSA boards and two PA amplifier boards in the repeater. One pair of BSA/PA boards for uplink signaling and one pair for downlink signaling. BA, High power CDMA booster amplifier board CDMA repeaters can be equipped with a high power booster amplifier board that boosts the output gain with typically 6dB. A high power CDMA repeater can operate with maximum 2 channels. 5-2 Rev.

Downlink signal path The signal from the base station is received via the repeater BS antenna and is then forwarded through a directional coupler (DC). The signal passes a duplex filter (DPX), is amplified in a low noise amplifier (LNA), and enters the channel board (CSA), which has two parallel channels. 5 - 12 Rev. P1A 2000-09 User’s Manual VD203 66/EN ALLGON System AB AR Repeaters Functional Description The first mixer stage on the CSA amplifier board, which is controlled by a synthesizer, converts the received frequency down to the IF frequency. The signal is then filtered by SAW bandpass filters and, not shown in the figure, amplified before it is fed to the second mixer stage for conversion back to the original frequency. The following power amplifier is controlled by the CU. The output gain can be reduced to avoid instability due to poor antenna isolation. The output signal from the power amplifier is fed to a combiner, which combines the signals from the two channels on the channel board. A detector on the PA board 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 several of the amplification stages. BA in high power CDMA repeaters only. In high power CDMA repeaters, a booster amplifier (BA) boosts the output downlink signal by typically 6dB. The BA amplifier is powered by a high power PSU2. Note that the booster amplifier (BA) is only present in the downlink path, and only in high power CDMA repeaters. The output signal passes a duplex filter (DPX) and a directional coupler (DC) before it is fed to the repeater MS antenna. User’s Manual VD203 66/EN Rev.

P1A 2000-09 User’s Manual VD203 66/EN ALLGON System AB AR Repeaters Functional Description The first mixer stage on the BSA amplifier board, which is controlled by a synthesizer, converts the received frequency down to the IF frequency. The signal is then filtered by SAW bandpass filters and, not shown in the figure, amplified before it is fed to the second mixer stage for conversion back to the original frequency. The SAW filter can be either fixed or adjustable depending on the BSA board used. If the BSA board has fixed band width, this SAW filter is fixed and selected for the current band width. If the BSA board has adjustable band width, the SAW filter combination can be software changed from within OMT32 (or OMS) to cover various band widths. The following power amplifier is controlled by the CU. The amplifier gain will be reduced to avoid instability due to poor antenna isolation. A detector on the PA board 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 several of the amplification stages. 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 the repeater (described in Chapter 6, Optionals). Communication with the base station is performed by means of a built-in mobile feature that has the antenna connected to the BS directional coupler (DC). Data is transferred between the repeater and the built-in RCU unit via the P32 modem port. The RCU unit is powered via the P27 auxiliary 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 RCU unit in one of the repeaters in an 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. User’s Manual VD203 66/EN Rev.

P1A 2000-09 6-7 Optionals AR Repeaters Allgon Systems AB OMS, Operation and Maintenance System The OMS, Operation and Maintenance System is an Allgon software package for controlling a large repeater fleet by using computers with Windows NT in networks with a common database. The OMS is capable of operating a large number of repeaters. Multiple modems 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 latter is replaced by the OMS and is no longer subject to further development. Traffic Statistics Traffic statistics is available for channel selective GSM 900, GSM 1900 and DCS/PCN 1800 repeaters, provided that the repeaters have the latest CU software versions, the latest CU and CHA boards, and that an OMS is used to poll and view the statistics. Battery Backup Battery backup can be arranged by completing the repeater with an Allgon UPS (Uninterruptible Power Supply). The Allgon UPS has an exterior similar to the repeater which means that it can preferably be mounted adjacent to the repeater. Fiber Optic Interface A Fiber Optic Interface that includes transmitter, receiver, alarm board and power supply is available for all the Allgon repeaters. The fiber optic interface can be adapted for separate uplink and downlink fiber as well as for bi-directional one-fiber distribution. 7/16" Antenna Cable Connectors A 7/16" antenna cable kit is available for all the Allgon repeaters. This kit includes 7/16" antenna connectors for uplink and downlink antennas mounted on two repeater cable inlet flanges, and cables and connectors for connection to the DC directional couplers inside the repeater. 6-8 Rev.
