This chapter identifies the particular technical problems and challenges which the successful satellite mobile service must address. Among these are the selection of an appropriate orbit and constellation, the trade-off among modulation and multiple access methods, and frequency reuse strategies to permit a cost-effective service without sacrificing bandwidth. This chapter also considers which of the planned systems has the greatest likelihood of implementation and commercial success.
