7.0 R-20-930 (One way paging) Repeater
This repeater has been designed to meet the requirement of indoor
coverage and is equipped to carry traffic in
a single sub band
of one MHz
bandwidth in the frequency band 92
9
to 930 MHz. Basically traffic carried in
this repeater is for transmitting signals in one direction only what can be
termed as DL path.
7.1 Salient Features
•
It is a band selective device & is equipped to handle signals in
a
single sub band
of one MHz bandwidth that is set as per
requirement in the frequency band 92
9
to 930 MHz.
•
It has been designed to amplify signals in one direction only i.e. the
down link path. It is installed at a suitable site between BTS and the
area intended for providing coverage.
•
It intercepts signals from the BTS through a
DONOR antenna
(highly
directional outdoor antenna) and distributes the signals to the users
after amplification through a set of
SERVER antennas
(omni/
directional) system in the D/L.
•
Design of filters permits high selectivity and excellent out of band
signals rejection.
•
The indoor antenna is specifically designed to blend into the ceiling
of a typical office providing RF signal in all directions downward and
outward from the installation point.
•
For in-building configurations requiring higher gain or directional RF
signal, such as a long hallway or corridor, a medium gain directional
antenna may cover the area best by mounting the antenna to the
opposing wall, where coverage is required.
•
It finds application in multi-storey buildings, basements & car parking
areas.

Typical In-Building Coverage
The R-20-930 (One way paging) repeater is designed to provide optimal
coverage for areas of 1000 Sq Meters (10,000 sq. ft) to 2,000 Sq Meters
(20,000 sq. ft). However, performance also depends on the amount of in-
