1. The Advantage of DMR

2. 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.
