4.5. General

Mobile Communications Syste ms are plan ned as cellu lar s ystems and each cell of the base station is required to provide RF coverage over a certain geographical area as per defined RF power levels. Due to the RF propagation p roper ties, even us i ng high r ad iated RF p owers or complicate d antenna systems, ther e are zones within the coverag e area where the RF signal strength from base station remains inadequate for establishing the desired connectivity to mobile users.

Repeaters traditi onally are deployed in the Mobile Communic ation Network to fill in the “Dead Zones” caused by blocking of signals by geographic topologies such as mountains, valleys, dense foliage, high rise urban landscapes and other man-made structures. The distance from the base station also adversely affects the RF signal strength. The user views repeaters as a means to extend base station covera ge so as to reduce the number of base stations and thereby accelerate network availability.

Repeater systems are installed after meticulous planning between BTSs and the mobile users to provide RF coverage in the shadowed regions. Repeater systems are available for different applications and ultimate choice shall depend on some of the factors mentioned below:

• Area to be provided with coverage.

• Indoor/outdoor coverage.

• Availability of BTSs in the vicinity.

5. Functiona l Description of BTS Link-104/108 Repeater

5.1. General Description

The BTS Link-104/108 Repeater System is designed to provide indoor/outdoor coverage (depending on the location of the remote optical unit installed) and is equipped to handle signals in AWS band. It provides highly selective amplification in the pre-set band. The detail of operating AWS service frequency band is given below:

Frequency Band

Down Link: 2110 MHz to 2155 MHz

Up Link : 1710 MHz to 1755 MHz

The Customer is requested to refe r to the sticker on the repeater unit giving the details of frequency band set.

• The BTS Link-104/108 repeater system is a single band

Distributed Antenna System (DAS) for point to point & point to multipoint coverage.

• It is comprised of a Master Optical Unit (MOU) and Single Band

Remote Optical Units (SBROUs), maximum 4 or 8, installed at different sites. Two versions are available; BTS Link-104 version

supports up to 4 SBROUs and BTS Link-108 supports up to 8 SBROUs. MOU & each of the SBROUs are connected through a

pair of optical fibers.

• For providing coverage in a large area, SBROUs with RF power of

+40dBm can bs installed.

• Master Optical Unit (MOU) is installed at indoor location close to

BTS from where the signals are to be received and OFC terminations destined for SBROUs at different sites are available.

• The repeater is deployed in the network where RF coverage is

required for large clusters of mobile users at different sites.

• The repeater can be equipped with a RMS (Optional) for speedy

maintenance & monitoring.

• The antenna isolation problem is of little consequence since the

signals between MOU and SBROUs are propagated as optical signals, which are insensitive to any electrical interference/disturbances.
