This book describes the design, construction, and testing of the experimental UNIVERSE information technology network and outlines the project's organization. Project UNIVERSE was developed in the early 1980s by a consortium of industrial, university, and government laboratories. It involves the combination of broadcast satellite and local networking technologies to form an integrated communication system. Applications of the network involve a variety of information technology systems, including slow-scan video, security, teletex, videotex, packet voice and conventional computer-to-computer communication. The book offers a unique case-study experience for use in communications courses as well as for researchers in the area.
