Design considerations for data networks via satellite systems
Abstract
The design of satellite data-communications systems is reviewed from a systems perspective, emphasizing the role of baseband functions. The basic types of services likely to be required in the immediate future and the traffic characteristics they imply are examined, and the need for an integrated design approach is stressed. The satellite-link equations are presented, and their implications for system design are discussed. Topics considered include propagation effects; antenna size; choice of multiple-access technique; demand assignment and channel multiplication; the interaction of switching, channel multiplication, voice processing, and DAMA; satellite delay; coding; encryption; and multitransponder networks. The typical basic design parameters of a data-collection/acquisition network, a small corporate network, and a large common-user digital network are listed in tables and compared. Drawings, block diagrams, and graphs of important physical relationships are provided.
