A basic system consists of a central office radio that is connected to the National Telephone Network and of a remote-located subscriber unit connected to a standard telephone. Depending on terrain features and antenna height, distances of up to 80 kilometers may be covered reliably. If the terrain is such that the radios are located out-of-range, repeaters are deployed. A repeater consists of two radio units that are connected back-to-back.

Typical applications include, remote villages, construction sites, isolated farms and cottages, logging and mining operations, hydro electric dams sites, temporary installations and payphone service.
