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:
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.
