The Advantage of DMR

DMR era has come analog digital Doubling of capacity in existing 12.5Khz licensed channels(TDMA) compatibility with analog systems Efficient use of infrastructure equipment Longer battery life and greater power efficiency Superior audio performance Doubling of capacity in existing 12.5Khz licensed channels(TDMA): a single 12.5 kHz channel to support two simultaneous and independent calls, achieved using TDMA. compatibility with analog systems DMR support analog mode and singel Efficient use of infrastructure equipment DMR can achieve that two communications channels with one repeater, one antenna and a simple duplexer. Longer battery life and greater power efficiency two-slot TDMA can enable up to 40 percent improvement in talk time in comparison with analogue radios. Superior audio performance(FEC) Forward Error Correction (FEC) analog digital
