1. A space-based component (SBC) of a communications system, the SBC comprising:
- a plurality of service link antenna elements configured to transmit/receive information to/from radioterminals;
a plurality of feeder links each providing information to/from a respective processing facility; and
a channelizer configured to map different spectral components of a service link signal received at the SBC via a service link antenna element to different feeder links of the plurality of feeder links and/or to map different spectral components of a feeder link signal received at the SBC via a feeder link to different service link antenna elements.
