Frequency re-use in the Intelsat system
Abstract
Intelsat IVA gains a substantial bandwidth advantage over Intelsat IV by reusing the 4/6 GHz frequency bands in Eastern and Western zones through spatial separation of antenna beams. Attention is given to a series of satellite coverage models for the Atlantic Region in which the amount of frequency reuse is progressively increased by means of spatial separation of beams and/or polarization discrimination. The use of 11 and 14 GHz frequency bands is also assumed in some of the models. An evaluation of the approximate channel capacity for each model is provided.
