CSr438
tetra - MISSION CRITICAL SOLUTIONS
CSR438
digital channel Selective Repeater
Large repeater coverage footprint due to high output power and gain
Very low propagation delay leading to higher security, resilience and availability of information
Easy system implementation with build-in commissioning tools
Time-slot based ALC
Supervision available over TETRA modems
Remotely upgradeable for TEDS
The CSR438 provides quick,
cost-effective and secure radio
coverage in any TETRA network and can handle up to eight
TETRA carriers. Through the use
of the CSR438 an operator can
easily expand a base station’s
service area by filling in coverage
holes caused by terrain, buildings
or tunnels.
The wireless interface permits
the operator to remotely configure RF parameters as well as
monitor alarms on a continuous
basis.
The CSR438 can be used as a
gap filler, filling in coverage holes
caused by terrain or buildings.

Site
The CSR438 can also be used to provide coverage in shorter tunnels. Longer tunnels can be covered by
connecting the repeater to an OMU (Optical Master Unit) that feeds a number of fiber fed repeaters.
