Abstract:
1. A satellite radioterminal communications system comprising: a first space-based component that is configured to communicate with a first radioterminal over a first forward link using a first band of frequencies and over a first return link using a second band of frequencies; a second space-based component that is configured to communicate with a second radioterminal over a second forward link using a third band of frequencies and over a second return link using a fourth band of frequencies and to receive return link communications from the first radioterminal over the second band of frequencies; and a combiner that is configured to combine return link communications received from the first radioterminal at the first and second space-based components; wherein the first space-based component is configured to exclude communications using the third band of frequencies and wherein the second space-based component is configured to exclude communications using the first band of frequencies; wherein the first band of frequencies comprises a first one of an S frequency band or an L frequency band and excludes a second one of the S frequency band or the L frequency band, wherein the third band of frequencies comprises the second one of the S frequency band or the L frequency band and excludes the first one of the S frequency band or the L frequency band wherein the first space-based component is configured to exclude transmission using the third band of frequencies and wherein the second space-based component is configured to exclude transmission using the first band of frequencies.
