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.
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.
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.
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 ot
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.
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.
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.
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.

Allgon Systems AB AR Repeaters Installation Mains Breakdown Relay To be able to distinguish PSU faults from power failure, a mains breakdown relay must be used on the repeater mains supply. The mains breakdown relay is not included in the repeater. So, it has to be mounted outside the repeater chassis. The relay intended for this purpose must fulfil the following specifications: Relay specification Closing time: max. 30 milliseconds Insulation coil/contact: min.

Allgon Systems AB AR Repeaters Commissioning 4. Commissioning Read carefully Chapter 1 Safety before commissioning the repeater. Check all connections made during the installation. Also, ensure that both the mains plugs for repeaters equipped with two power supply units are connected to outlets supplied from the same fuse. To fulfill the IP65 weather protective requirements, ensure that the cable strain relief bushings are properly tightened.
Commissioning AR Repeaters Allgon Systems AB Starting the Repeater 1. Turn the mains switch on (marked ’S’ in Figure 4-1). 2. Check the LED on the power supply unit (V). It must be lit with a steady yellow light. 3. Check the four CU board LEDs (see Figure 4-1). A correct power up is indicated as follows: PWR Yellow LED which is lit with a steady light after the mains is switched on. Indicates present power.

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.
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.
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.
ALLGON System AB AR Repeaters Functional Description Other units In addition to the channel/band selective boards, the repeater contains: • DIA Distribution board, which is a board on which all other boards and units are connected to.
