DMR Radio Standards

DMR, Digital Mobile Radio, is a digital radio standard specified for business mobile radio users developed by ETSI, European Telecommunications Standards Institute, and first ratified in 2005.

The standard is designed to operate within the existing 12.5kHz channel spacing used in licenced 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 standards that define multi-vendor DMR consist of four documents. These can be downloaded free of charge from the ETSI website.

The DMR Association concentrates its resources on the commercial applications of DMR comprised in Tier II and Tier III trunked.
