Digital Mobile Radio (DMR) is a digital radio standard specified for professional mobile radio (PMR) users developed by the European Telecommunications Standards Institute (ETSI), and first ratified in 2005. Increasingly, Critical Communications agencies including Public Safety, Transportation, and Utility are deploying DMR radio systems in VHF, UHF, and 800 MHz.

The standard is designed to operate within the existing 12.5kHz channel spacing used in licensed land mobile frequency bands globally and to meet future regulatory requirements for 6.25kHz channel equivalence. The primary goal is to specify affordable digital systems with low complexity. DMR provides voice, data and other supplementary services. Today, products designed to its specifications are sold in all regions of the world.

The DMR protocol covers unlicensed (Tier I), licensed conventional (Tier II) and licensed trunked (Tier III) modes of operation, although in practice commercial application is today focused on the Tier II and III licensed categories.

The standards that define DMR consist of four documents which can be downloaded free of charge from the ETSI website, as well as the console wireline interface standard, AIS.

Catalyst Communications Technologies is an active member of the DMR Association, which is a global organization focused on helping to make DMR the most widely supported 21st century digital radio standard.  Many worldwide radio manufacturers have developed radio equipment to operate on the DMR standard, thus increasing competition and product availability. Catalyst can provide both a wireless and a wireline (AIS) interface to DMR systems.
