Digital Private Mobile Radio (dPMR) is a standard that has been developed by ETSI and defines digital Professional, Personal and Private Mobile Radio (PMR). PMR has enjoyed great success in Europe for many years, and serves a very broad community of users.

dPMR is a Frequency-Division Multiple Access (FDMA) system offering the lowest cost digital voice and data solutions for PMR. Until recently, PMR technology that used Time-Division Multiple Access (TDMA) was more spectrum-efficient at wider channel spacings such as 25kHz. The ETSI dPMR standard solves the problem of shortage of radio channels by introducing 6,25kHz FDMA radios with a 4FSK modulation scheme. This newly-developed narrowband 6,25kHz FDMA technology, as used by dPMR, brings greater spectrum efficiency with lower infrastructure cost.

Although the market landscape for two-way radio varies somewhat throughout the world, markets can be roughly divided into three broad categories. dPMR has the universal capability to serve them all :

1. Consumer (and short-range industrial)
2. Professional/Business-Critical applications
3. Public Safety/Mission-Critical applications.

dPMR is a scaleable system that can be used in unlicensed mode (in a 446,1 to 446,2 MHz band), and in licensed mode, subject to national frequency planning. It is developed in ‘tiers’:

- Tier 1 is the low-cost, licence-exempt 'digital PMR446', and is defined by ETSI Technical Specification TS 102 490.
- Tier 2 is for the licensed professional market, offering peer-to-peer mode (Mode 1), repeater mode (Mode 2) and trunked (managed access) operation (Mode 3). Tier 2 is defined by ETSI Technical Specification TS 102 658.

The dPMR specifications can be obtained free of charge from the ETSI website publications download area (http://pda.etsi.org/pda).

About ETSI
dPMR is part of ETSI – one of the world’s leading standards development organizations for Information and Communication Technologies (ICT). Founded initially to serve European needs, ETSI has grown rapidly to become highly-respected as a producer of technical standards for worldwide use.

ETSI membership is composed of manufacturers and network operators – all the “big names” and many smaller companies too – plus national administrations, ministries, regulators, universities, research groups, consultancies and user organizations. A powerful and dynamic mix of skills, resources and ambitions, all working together to bring the very best ICT solutions to the global marketplace. Geographically, our membership of over 700 companies and organizations is drawn from more than 60 countries on 5 continents.

ETSI is independent of all other organizations and structures, a key feature for ensuring neutrality and trustworthiness. That brings benefits not only in the acceptance of our standards and other publications, but also in our growing range of ancillary services, such as interoperability testing. And because standardization inevitably draws upon the bright ideas of our members, we have an Intellectual Property Rights (IPR) policy in place that has become the model for many other organizations.

ETSI's standardization activities are open to all interested companies and organizations. Your company can be part of this dynamic organization. For more information about how you can be involved, please visit http://www.etsi.org/membership
