I
t receives signals from the
BTS
through a
DONOR
antenna
(
highly
directional outdoor antenna
)
and distributes the signals to mobile users
after amplification through
SERVER
antenna(s) of directional type in
the

, the signals from the mobile users are picked up by
SERVER antenna and retransmitted to the
BTS
after amplification.

T
he repeater finds applications in tunnels, highways, large size
airports, and open market areas etc. where traffic requirement is high.
•
T
he system can be incorporated with optional

which can be used for configuration and monitoring
the status of the link. It helps not only speedy maintenance but remote
configuration also through wireless modem.

A
metallic case houses the repeater. Arrangement is made for heat
dissipation especially for amplifiers, which generate more heat.
T
he
choice of suitable metal as the case material gives a lightweight design
with good heat conduction and waterproof protection.
T
