TDMA: How It Works
DMR, which stands for Digital Mobile Radio, uses TDMA digital technology. TDMA stands for “Time-Division Multiple Access.” Like FDMA, or “Frequency-Division Multiple Access,” TDMA is a technology that allows multiple conversations to share the same radio frequency. Although the goal is the same, the two technologies work very differently.
Since TDMA transmits timed pulses, two different conversations can occur on the same frequency simply by transmitting at alternating pulses or “time slots”.

Other cool benefits of a “pulsed” signal is that it is not continuously transmitting like an analog signal or FDMA is therefore increasing your battery life. Usable range is also increased as well as the audio quality.

Two voice conversations at the same time on the same frequency Time slot 1 – conversation 1 Time slot 2 – conversation 2 Both occur on the same frequency at the same time
