Digital Mobile Radio (DMR)
Increase Capacity and Improve Communications with Digital Mobile Radio
Digital mobile radio (DMR) is created by leading manufacturers and certified by the European Telecommunications Standards Institute for an open standard that is a direct digital replacement for analog private mobile radio (PMR).
DMR solutions have many advantages over other digital PMR or land mobile radio (LMR) technologies targeted at the critical communications and commercial sectors.
At Leonardo, drawing on our 100-plus years of experience in providing all methods of wireless communications, we provide critical communications to utilities, public safety, transportation and large business enterprises.
Digital Mobile Radio: Features
- Created by leading radio manufacturers, DMR is an open standard certified by the European Telecommunications Standards Institute (ETSI).
- The ETSI DMR standard provides an easy migration path from analog to digital PMR technology.
- The use of a two-slot time division multiple access (TDMA) delivers a reliable, doubling of capacity in a technology that aims to provide a lower cost, less complex digital solution that is scalable and flexible.
- Leonardo ECOS-D architectures include repeaters for standalone sites, simulcast, multi-cast and a hybrid of the two. Leonardo offers DMR trunking topologies as traditional centralized, fully distributed, or a hybrid of the two.
- DMR Tier II solutions are complemented by DMR Tier III “trunking” solutions designed to cope with higher traffic volumes given the capability to manage multiple frequency pairs.
Doubling Of Capacity In Existing Licensed Channels
Using a TDMA access method, DMR enables a single 12.5 kHz channel to support two simultaneous and independent calls, doubling capacity.
Interoperability Between Manufacturers
DMR interoperability process (IOP) provides for testing of radios to ensure compatibility between manufacturers and offer choices to end users.
Superior Audio Performance
DMR technology provides better noise rejection and preserves voice quality over a greater range than analog, especially at the farthest edges of transmission range.
