DMR is trusted by over 15 million users worldwide
Our resolute team are proud to provide unrivalled support to its global members and the assurance that digital mobile radio is the most widely used digital radio standard for the business world.
The DMR Association’s mission, since 2005, has been to support the European Telecommunications Standards Institute during the DMR standardisation process. To provide the ultimate service to our members we focus on the commercial applications of DMR comprised in Tier II and Tier III.
We welcome new members from across the globe. Whether you are a business that utilises DMR, or an individual that supports the professional use of the DMR standard, you’ll be in great company. We truly appreciate your help in enabling us to drive forward our mission.
We combine our knowledge and expertise with education, awareness, certification, and interoperability training to guarantee that today’s digital radio technology customers experience the highest level of service. We invest our time and energy to futureproof your investments.
As a member of the DMR Association you’ll benefit from the frequent and direct communications that we hold with global regulators, trade bodies and standards organisations. We are committed to ensure that all DMR products reach the market within a successful, open, multi-vendor chain and that our members gain from continuous, competitive development.
DMR applications interface standards unify interoperable voice and data solutions across multiple technologies and manufacturers.
The interface was developed by members of the DMR Association with the goal of enabling applications to benefit from interoperability between an application and DMR infrastructures from different vendors.Application Interface (AIS)

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 >
Optimising standards, extending capabilities, and reducing costs through the creation of multiple and mutually compatible products.
The primary goal is to specify affordable digital systems with low complexity. DMR provides voice, data and other supplementary services. Today, products designed to its specifications are sold in all regions of the world.The DMR Standards
