Abstract :
Communication by broadcasting, although most effective in terms of broad area coverage at relatively low cost, is subject to reception interference which is often uncontrollable. In heavily populated urban areas these severe and changing interference problems, as well as limited electromagnetic spectrum, are inherent to the environment. Communication by wire, a point-to-point coverage independent of the electromagnetic spectrum, presents a solution to these problems. The communications engineering community is encouraged to develop transmission standards for the wired system that are compatible with broadcast transmission standards, and transmission testing for wired systems is reviewed.
