Abstract: The paper describes the development of mobile communication first, and then, after comparing the cellular mobile communication with the satellite mobile communication, points out it is necessary for China to develop satellite mobile communication.After comparing the geostationary satellite system with the low earth orbit satellite mobile communication system, as well as the single beam with the multi-beams, both used in satellite mobile communication,according to its economic status and level of satellite technology, except international satellite mobile communication the paper suggest that China, should develop a geostationary multibeam satellite for its domestic mobile communication.
