Specialist Task Force 403:
Test specifications for the protocol conformance and interoperability of digital Private Mobile Radio devices

Who we are:

Team Leader: Pete Hizzey, Icom,
Team Members: Caroline Maragnon, Icom,

What we do:

This STF is developing test standards for conformance and interoperability for dPMR radio equipment. dPMR radios exist in three different levels of functionality, Modes 1, 2 and 3.

Interoperability and conformance test standards have already been developed for Mode 1 dPMR and the purpose of this STF is to update these standards to include all the Mode 2 requirements.

For more details, see our Terms of Reference

Why we do it:

With any form of protocol that governs the functionality of electronic equipment it is essential to have independant standards for interoperability that can be used to prove products from different manufacturers will work together without conflict. It is only by having proven interoperability based on independant standards that consumers can be confident that a ‘mulitple vendor’ status exists for any given technology.

Furthermore, the dPMR MoU manufacturers association have adopted the ETSI interoperability standards as the benchmark for product approval and the attribution of an approval trademark.

How we do it:

Clearly we need to have a close working relationship with dPMR product developers and radio manufacturers. The dPMR interoperability standards already developed by previous STFs have been used to de-bug dPMR chip sets, radio products and the published dPMR protocol standard itself (TS102 658). It is often found that questions of interoperability arise because of inadequate explanation of the protocol so the constant feedback from the design departments of various manufacturers has been invaluable in drafting and maintaining both the air interface standard and these test standards.

Members of this STF have direct contact and access to dPMR design engineers, silicon and protocol developers as well as the dPMR MoU association and the drafting team of the air interface protocol. Input from all of these elements is necessary to ensure quality standards. 


The Mode 1 interoperability standards were published as:

TS102 795

TS102 726-1, TS102 726-2 and TS102 726-3

The deliverables will be revised versions of the above, including all the dPMR Mode 2 requirements.

Time plan:

Stable drafts expected September 2010

TB approval expected January 2011
