The Digital Mobile Radio Association
Digital Mobile Radio Association (DMR) members are companies, organisations and individuals who use or build DMR products, or those who support the DMR standard in other ways. The DMR Association has a number of members classed as ‘category one’. These manufacturers have signed a memorandum of understanding to ensure that their products use mandatory features of the ETSI DMR standard to provide interoperability. Manufacturers may also choose to add optional features.
Although the ETSI DMR standard does not specify the use of a particular vocoder, DMR Association members have agreed to use the Advanced Multi-Band Excitation (AMBE+2) half-rate vocoder to ensure compatibility between equipment.
