ALLGON System AB AR Repeaters & OMT32 Hardware – 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.
ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction Repeater Types The following repeater types are available: • • • • • Channel selective GSM repeater Channel selective CDMA repeater Band selective repeater with fixed band width Band selective repeater with adjustable band width 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.

ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction 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 System AB AR Repeaters & OMT32 Hardware – 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 System AB AR Repeaters & OMT32 Troubleshooting 12. Troubleshooting This chapter contains the following sections: • Active alarm, page 12-2 What to do when an active alarm is generated • Modem debug tools, page 12-4 Fault tracing tools for troubleshooting the OMT modem and the repeater modem. • R2R, communication problem, page 12-5 Verification of the link communication speed. • R2R, advanced node configuration, page 12-6 Fault tracing tool for advanced troubleshooting.
ALLGON System AB AR Repeaters & OMT32 Troubleshooting Active Alarm This section describes what to do when an active alarm is generated. Power supply check • Check the front LED to see if the repeater has power or not. If it has, go to the Other faults section below. If it has not, proceed with the Power failure alarm section. Power failure alarm • Check the mains outlet and the mains cable to the PSU. • If the PSU has power but the repeater has not, the PSU is faulty.
ALLGON System AB AR Repeaters & OMT32 Troubleshooting Other faults Open the repeater cover and connect an OMT32/PC to the repeater. Open the Repeater Event Log and check the cause of the alarm. • If an antenna isolation alarm is indicated, the antenna isolation should be measured.
