●DMR and analog conventional mode.
●Extensible 32 simulcast base stations per control centre.
●Multiple simulcast areas , and interconnect with diﬀerent areas .
●Real time Voting:Voice selecting technology in overlap area, the system selects a best voice frame through realtime voting.
●Centralized control centre , conventional controller and simulcast controller are centralized in one center, each simulcast base station with olny RF components which is easy for maintenance.
●Digital transceiver with large LCD developed independently, modular and compact design, digital and analog mode, high reliability and stability .
●Automatically measure transmission delay , accurate to 1μs .
