DMR Mobile Radio
Rx RM750 is a base & Mobile station and also function as single frequency repeater function (Optional) solution. As a single frequency repeater, Rx-RM750 allocates one timeslot to receive a signal and the other to transmit it at the same frequency, using DMO (Direct-Mode-Operation) mode to extend radio coverage.
- Base Station/Repeater Dual Modes
- Extend DMO (Direct-Mode-Operation) Communication Distance
- Cost effective DM Repeater Solution
