Abstract:
1. A method of operating a communications system including a space-based network comprising a satellite and a terrestrial network comprising a base station, the method comprising: receiving communications at the base station from a radioterminal using frequencies from a first satellite frequency band; communicating from the base station to the radioterminal using frequencies from a second satellite frequency band; and communicating directly between the satellite and the radioterminal using at least some of the frequencies from the first satellite frequency band and/or at least some of the frequencies from the second satellite frequency band, wherein the first satellite frequency band comprises a first one of an L-band of frequencies and an S-band of frequencies and wherein the second satellite frequency band comprises a second one of the L-band of frequencies and the S-band of frequencies, wherein the communications between the satellite and the radioterminal do not use frequencies from the first satellite frequency band.
