Public Protection and Disaster Relief (PPDR) radiocommunication systems are vital to the achievement of the maintenance of law and order, response to emergency situations, protection of life and property and response to disaster relief events.
Radio communications background State Radio had its inception in the 1940s with a lowband (39 MHz) system consisting of a few towers that were tied together with radio (RF) links. The lowband radio frequency offered the greatest range and required the least number of stations. In the early 1960s, the statewide
“Interoperability” is the ability of emergency response agencies to talk to one another via communication systems—to exchange voice and/or data with one another on demand, in real time, when needed, and as authorized. The foundation for interoperability, however, is basic communications within emergency response agencies—simple “operability.”
