Key features of the DMR standard

  • Interoperability between manufacturers
  • Backwards spectrum compatibility
  • State of the art Forward Error Correction
  • IP Data
  • Fast Automatic Vehicle Localisation (AVL)
  • Optional encryption for secure communications
  • Doubling of capacity in existing channels
  • Data applications interface (AIS)
  • Two-slot Time Division (TDMA) operation

DMR enables a single 12.5 kHz channel to support two simultaneous and independent calls. This is achieved using TDMA, Time Division Multiple Access. Under TDMA DMR retains the 12.5 kHz channel width and divides it into two alternating timeslots A and B where each timeslot acts as a separate communication path.

Each communication path is active for half of the time in 12.5 kHz of bandwidth, each uses an equivalent bandwidth of half x 12.5 kHz or 6.25 kHz. This is known as having an efficiency of one talk path per 6.25kHz of spectrum. However with DMR the channel as a whole maintains the same profile as an analogue 12.5kHz signal.

This means that DMR radios operate in the licence holders existing 12.5 kHz or 25 kHz channels; there is therefore no need for re-banding or re-licensing but at the channel capacity is doubled. Read More >
