dPMR – a simple and cost effective digital PMR Technology

dPMR was introduced in 2007 and is an ETSI compliant open FDMA digital protocol. The concept was to offer the market a logical migration solution from analogue to digital radio communications designed around the idea of employing proven technology, compatibility with existing analogue equipment, simplicity and low cost.

One of the core requirements for success of any new technology is interoperability

The dPMR association will be active in ensuring an independant validation of interworking between dPMR products from different manufacturers and authorising the use of a specific dPMR logo for compliant equipment. These interoperability tests will also be based on ETSI standards. Visit our Interoperability section

dPMR appeals strongly to both users of existing analogue systems and the those who only need to operate one base station and a few portables and mobiles, or small radio-linked communities where the reasonable cost of dPMR equipment makes it is a very sensible proposition. Another of the advantages of dPMR is the flexibility of the products and solutions on offer. Read more

While the world of PMR has been driven over recent years by advances in digital technology, there remains a huge body of users with large existing analogue or partially digital systems (both conventional and trunked systems like MPT 1327) who simply don’t require all the more advanced features and capabilities of full digital operation just yet. dPMR provides an ideal solution for these users as all they have to do is to incorporate a repeater or digital trunking controller in their system to have the choice of operating in analogue and/or digital modes.

Of course, there are other users who are building or renewing their systems and want to employ digital and this where dPMR offers a competitive alternative which many users are choosing. Read more

dPMR is an ETSI Standard - Why is this important?

ETSI standards could be described in general as being 'definitions and specifications for products and processes requiring repeated use'. They are certainly a set of rules for ensuring quality. ETSI are officially recognised by the European Union as a European Standards Organisation. The FDMA protocol specified in both TS102 490 and TS102 658 ETSI standards complies with the European Harmonised Standard EN301 166-2 for use in 6,25 kHz channels. Read more

The dPMR community is represented by some of the biggest companies in global radio communications:

The dPMR Association is open to any manufacturer, supplier, user group, administration or laboratory that share our aims for promoting narrowband FDMA technology. With 17 active members, representing some of the biggest companies in global radio communications contributing to its development, you can look forward to the continued success dPMR technology with confidence.

dPMR’s growing community includes the end user, arguably the most important contributor to the success of dPMR:

This is evident in the growing number of projects being deployed. Please take a closer look at our Case Studies section for more detailed information on a selection of handpicked systems examples that are already established around the world.

United Nations
Humanitarian Community:

While the specific details of dPMR systems deployed by the United Nations and related agencies are naturally confidential, Mode 2 dPMR systems are increasingly being utilized for by a number of humanitarian agencies for many applications ranging from communications training to in-field systems in specific hotspots around the world. Some agencies have also made the move to standardize on dPMR for their future digital communications. (Above photo: by U.S. Marine Corps - Sgt Bryson K. Jones)

Airports, Prisons, Police, Local Government and Hospitality:

While dPMR was not specifically designed as a mission critical protocol, it has been effectively implemented in mission critical sectors including prisons and the police service, airports and local government authorities (both in Mode 2 conventional and Mode 3 trunking) Other typical users include the business and industry sector such as transport companies and hospitality have also opted for dPMR systems.
