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. Base Station 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.
