The dPMR Trademark

What it means:

The dPMR Trade Mark is a sign to users that equipment conforms to the ETSI standard and will interoperate with other equipment with the same marking.

This Trade Mark is attributed by the dPMR Association to any radio, system or infrastructure that can demonstrate compliance with the required conformance and interoperability standards. These standards are published by ETSI, as are those for the dPMR Air Interface protocol. dPMR equipment will have to comply with the ETSI TS102 726 multipart standard for conformance and interoperability and dPMR446 with the TS102 587 multipart standard.

This use of open ETSI standards for protocol, conformance and interoperability ensures that users can have the highest confidence in sourcing equipment from any vendor who has received the Trade Mark from the dPMR Association.

How to get it:

The dPMR Association will grant use of the dPMR Trade Mark to manufacturers of equipment that has demonstrated, to the satisfaction of the dPMR Association Technical Group, that it complies with all relevant parts of the ETSI conformance and interoperability standards.

Applicants will be invited to complete a functionality table for their equipment, such as that found in the ETSI TS102 726 PICS document. The testing applicable will be decided by the declared functionality. The dPMR Technical Group will also specify which current dPMR products shall be used for the purposes of the interoperability testing.

Applicants may then undertake the nominated testing in the presence of a dPMR Technical Group member or at an independent test laboratory of their choice.

Product classification marking of TS102 490 unlicensed dPMR 446 compliant equipment:

To assist users in the selection of appropriate dPMR products and solutions for specific applications, the dPMR Association have introduced Product Classes to distinguish between the compatibility and capabilities of different dPMR compliant equipment.

This interoperability classification is principally required for TS 102 490 compliant equipment (e.g. for dPMR446), where different compliant Vocoders are permitted but will not inter-work with each other.
