About DMR

DMR, or Digital Mobile Radio, is a digital two way radio technology.

It uses a time domain two-slot (TDMA) architecture to send messages and this improves the sprectral efficiency.

In plain English, it allows two concurrent radio signals to exist on the same frequency simulatenously.

There are a number of advantages to this, not least of which is the fact that two conversations can take place at the same time, without interfering.
