DMR Association announces completion of three interoperability testing sessions

The Digital Mobile Radio (DMR) Association today announces the completion of three further successful DMR interoperability test sessions. Two sessions were for DMR Tier III (trunked operation) and the third session for Tier II (conventional operation).
