Abstract
A communications network (100) for maximizing bandwidth utilization. An embodiment of the invention comprises a spacecraft (11), at least one gateway (12) communicatively coupled to the spacecraft (11) by a feeder link (13) operating within at least one selected frequency band within a bandwidth, at least one user terminal (16) communicatively coupled to the spacecraft (11) by a user link (17), the user link (17) operable at any frequency band within the bandwidth without regard to polarization; and, the communications network (100) adapted to provide for simultaneous operation of at least a portion of the feeder link (13) and a portion of the user link (17) at a common polarization and frequency band within the bandwidth.
