Digital mobile radio (DMR) technology offers reliable and flexible voice communication services anywhere a communications network is required. With the proliferation of VoIP, DMR networks may be interconnected to build larger systems via local or wide area IP networks. In most cases fibre or copper backhaul can be utilised to interconnect these systems. However, in many remote areas, fibre or copper backhaul may be cost prohibitive and thus satellite networks may be the only means to connect the local DMR network to the outside world. Although DMR-over-satellite is not a new topic in the telecommunications industry, it does get overlooked.
This presentation is a backgrounder to DMR and satellite communication (SATCOM) technologies and then discusses the possibilities of DMR over satellite. In essence, DMR over satellite can combine the efficiency and convenience of a push-to-talk (PTT) radio network with the global accessibility of a satellite network. This technology is expected to permeate oil and gas, police, public safety and other sectors.
