Professional DMR Repeater Module

BF-TR900

BF-TR900 is a highly integrated DMR repeater in the BelFone BMC system with the ruggedness of IP54 and MIL-STD-810G Standard to tackle various harsh environments. This versatile repeater can function as a ﬁxed base station, and it supports IP networking as well as simulcasting mode. Unlike traditional repeaters, BF-TR900 runs with a self-inspection circuit and module redundancy to ensure steady and reliable operation.

Multiple Working Modes

- Repeater mode
- SDC base station (Smart Digital Connect, BelFone Centralized IP interconnect system).
- Simulcast base station
- Channel unit of SDP (virtual trunking) base station
- PSTN gateway (working with BF-TC981)

Modular Design for Flexible Deployment

- Renewable transceiver
- Baseband module
- Be replaced easily if faulty

Ease of Maintenance

- The transceiver and baseband module can be easily replaced or changed to another frequency band. It supports upgrade to Simulcast Base Station working mode
- PA module can be replaced easily or changed to another frequency band. Both PA module and transceiver module need to be replaced together when frequency band needs to be changed.

ID Authentication for Air Interface

Only ID-authenticated legitimate terminals can activate repeaters for voice and data service forwarding, thus avoiding illegal users from stealing and occupying channel resources and affecting normal communications.
