ALLGON System AB

AR Repeaters & OMT Introduction

Introduction

Allgon repeaters are used to fill out uncovered areas in cellular mobile

systems, such as base station fringe areas, road tunnels, busirEss 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.

Operation of the repeaters is performed using a desktop or notebook and the

Allgon

OMT

(Operation & Maintenance Terminal) which communicate,

locally or remotely

via

modem, with the repeaters.

There is also an Allgon OMC (Operation & Maintenance Center), which is

intended to be used to

run

many Allgon AR repeaters.

The repeaters and the

OMIT

is described in this manual. The OMC is

described in the

Advanced Repeater 0MG, User’s Manual.

Band Selective Type e5ndteIe~tiVf~ repeftter ~‘ Figure 5-20. Band selective configuration The left-hand part of the configuration window contains downlink information (BSA board #1 and PA board #1 located to the left in the cabinet or cover). The right-hand part of the configuration window contains uplink information (BSA board #2 and PA board #2 located to the right in the cabinet or cover). The downmost line indicates current band width and the band width status (fixed or adjustable).

Field descriptions: Bandselective repeater The band selective repeater, or the band selective part of a combined repeater, can be turned on/off by clicking this box. The PA boards and the AGC (Automatic Gain Control) are turned off when the band selective repeater is switched off. ‘Downlink’ section Low band edge Displays the downlink low band edge related to the uplink low band edge. The difference is depending on the system duplex spacing.
