DSPbR® VHF/UHF/700/800MHz Repeater


The DSPbR is a compact, 19" rack mountable, RF-transparent digital channelised repeater that is configurable to deliver large outdoor coverage footprints, or to act as a headend for large or small in-building or in-tunnel Distributed Antenna Systems (DAS). The DSPR's innovative plug'n'play modular design, compact size, and a feature-rich configurability make the DSPR series ideally suited for a wide range of outdoor, in-building, in-tunnel and other specialised rebroadcast and coverage enhancement applications.

DSPbR Features:

This unit is a compact 19" rack mountable, RF-transparent, digital channelised repeater. Non-frequency translating or frequency-translating operation can be provided - either within one frequency band - or cross-band. The DSPbR is fully programmable, on a per-channel basis, and can provide the rebroadcast of one or multiple channels that can be connected off-air, locally coupled or fibre-fed, in one or more frequency bands. Point-to-point, point-to-multipoint, drop-and-insert, RFOF Summing and Simulcast configurations are all available using the DSPbR product platform.

The DSPR's plug'n'play modular design is capable of providing high per-channel RF output powers to deliver large outdoor coverage footprints or to drive large in-building or in-tunnel Distributed Antenna Systems (DAS). Low per-channel RF output power configurations can also be deployed to provide small black-spot coverage infill or to drive small-scale DAS designs. Many operational parameters are configurable through the user-friendly integral webserver GUI - including per-channel frequency, gain, channel bandwidth, RF output power, input signal level gating, alarm thresholds and reporting. Connectivity to the DSPbR is available via TCPIP, USB, RS232 or integral cellular modem. External inputs can also be monitored, such as equipment cabinet door switches, that can be included in the DSPbR's alarm monitoring and reporting. Alarms can be provided via SNMP Traps, Email (SMTP), SMS, or dry relay contacts.

Innovative design, compact size and a feature-rich configurability make the DSPR series suited for a wide range of outdoor, in-building, in-tunnel and other specialised rebroadcast and coverage enhancement applications.
