On Distributed Communications Series

VI. Mini-Cost Microwave


This Memorandum is one in a series of eleven RAND Memoranda detailing the Distributed Adaptive Message Block Network, a proposed digital data communications system based on a distributed network concept, as presented in Vol. I in the series. Various other items in the series.[1] deal with specific features of the concept, results of experimental modelings, engineering design considerations, and background and future implications.

The series, entitled On Distributed Communications, is a part of The RAND Corporation's continuing program of research under U.S. Air Force Project RAND, and is related to research in the field of command and control and in governmental and military planning and policy making.

The present Memorandum, the sixth in the series, is a detailed consideration of a possible design for the network's communications links, based on the use of micro-wave repeater stations. Of the several possible link designs presented in Vol. I, the mini-cost microwave appears least expensive. The mini-cost system is designed solely for use in transmitting digital signals within the Distributed Adaptive Message Block Network. However, many of its specific facets might be of use in other microwave applications.

Costs are factored out in detail, demonstrating more specifically the advantages of the microwave link. Two receiver designs further facilitate evaluation of the general proposal. The two other principal components of the distributed network--the Switching Node and the Multiplexing Station--are described in Vols. VII and VIII in the series.
