Abstract
A two-way communications system for use with a host computer includes a control unit, a base station and multiple radio/data terminal units. The control unit interfaces directly with the computer but uses a radio link to the portable units. Voice and data signals can be transmitted and data between units is decoded, sorted, stored, encoded, and sent to its destination in accordance with predetermined protocol in queue discipline. An extensive self-diagnostic system is included. An active redundancy arrangement switches between two control units/base stations on a regular schedule if both units are up, and instantaneously if the 'on' unit goes down.
