Abstract

A space-based network for a satellite radiotelephone system includes at least one receive-only satellite (1320a, 1340a) and at least one transmit satellite. The transmit satellite can be a transmit-only satellite (1310) or a transmit and receive satellite. The receive-only satellite(s) are configured to receive wireless communications from a radiotelephone at a location over a satellite frequency band. The transmit satellite(s) are configured to transmit wireless communications to the radiotelephone at the location over the satellite frequency band. By providing at least one receive-only satellite and at least one transmit satellite, space-based networks can offer a significant link margin, without the need to undesirably burden the radiotelephones themselves to achieve this link margin.
