dPMR introduction

dPMR stands for “digital Private Mobile Radio” and it is an open standard digital radio protocol published by the European Telecommunications Standards Institute (ETSI). dPMR utilizes 6.25kHz narrowband FDMA technology with the AMBE+2™ voice codec that offers many forms of voice and data applications.
The dPMR standard (TS 102 658) has three operating modes:

  • mode1Direct peer-to-peer mode
  • mode1Conventional repeater mode
  • mode1Centralized trunked network mode

IDAS dPMR products support basic conventional Mode 1 and Mode 2 operation at this stage.

The dPMR standard is delivered under the initial responsibility of the dPMR MoU group under the mandate of ETSI. The dPMR MoU group selected the standard vocoder and will perform interoperability and conformance testing using ETSI standards. Through evaluation testing, dPMR equipment will interoperate with each other, ensuring longevity of the system, a multi-vendor environment and a good return on investment.

March 2007 dPMR MoU group was founded with the first member companies
September 2008 Four new members joined the dPMR MoU group for a total of nine members
December 2008 dPMR standard (TS 102 658) was published
November 2009 dPMR interoperability and conformance testing standards
(TS 102 726) were published
July 2010 The first dPMR Tier 2 standard radios, IDAS dPMR radios released
IC Ff4029SDR

The IC-F4029SDR is a 500mW low power radio which does not require individual licensing. The IC-F4029SDR provides direct peer-to-peer digital voice + data mode communication.

The dPMR standard also defines a centralized trunked network mode (Mode 3) similar to the analogue MPT 1327 trunking in configuration and operation. *

dPMR™ mode 3 will support

  • Multi-channel, multi-site digital radio networks managed by centralized control channels
  • Call queue management using priority call and emergency call
  • Call diversion to another radio
  • Radio authentication service

*IDAS dPMR products support basic conventional Mode 1 and Mode 2 operation at this stage.
