Abstract This study forecasts the total demand for communications services, and satellite transmission services at the 4/6 GHz,12/14 GHz and 18/30 GHz fre- quencies. The services are voice, video and data services. Traffic demand, by service, is distributed by geographical regions, population density and distance between serving points. Further distribution of traffic is made among four major end user groups: Business, Government, Institutions and private individuals. A traffic demand analysis is performed on a typical metropolitan city to examine seruice distribution trends. The projected cost of C and Ku band satellite systems are compared on an individual service basis to projected terrestrial rates. Sep- aration of traffic between transmission systems, including 1 '30 GHz systems, 1s based on cost, user, and technical considerations. 17. Key Word (Suggested by Authw(s) I 18.
