Alternative Communication Network Designs for an Operational Plato IV CAI System.
Morley, Robert E., Jr.; Eastwood, Lester F., Jr.
Alternative communication networks for the dissemination of PLATO IV computer aided instruction were designed and comparative cost estimates were made for leased telephone lines, satellite communications, UHF TV, and low-power microwave radio. Costs per student contact hour were computed on the basis of student population density in public schools for a given market area. Analysis indicated that radio distribution techniques were cost optimum over a wide range of conditions. (Author/SK)
