DMR - Trusted by 12 Million Users

Welcome to the DMR Association; we’re here for our members, working worldwide, to continuously reaffirm Digital Mobile Radio as the most widely used digital radio standard for the business world.

We began in 2005 as a group of market leading public mobile radio manufacturers to support ETSI during the DMR standardisation process.

The DMR Association’s Technical Working Group works constantly on the Interoperability process, providing standards certification for manufacturers, the majority of which is at the highest Tier 3 specification. Membership is open to all organisations or individuals where DMR is a regular part of their business and for those working to support the professional use of the DMR standard in other ways.

DMR Key Benefits

Our Mission

By using a combination of education, awareness, certification and interoperability training we operate to make sure that business buyers of today’s digital radio technology have the security of knowing that they are investing in the future.

Here at the DMR Association we provide our membership with the resources necessary to make certain that DMR products reach the market within a successful, open, multi-vendor chain. We’re in frequent and direct dialogue with regulators, trade bodies and standards organisations around the world to maintain the standard.


DMRA Mission

DMR applications interface (AIS) standards unify interoperable voice and data solutions.

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 >
