Abstract
Conducting communications via a satellite includes using an antenna subsystem to provide fixed location spot beams. The spot beams may be assigned to beam groups according to an objective. At least one transmit-side switch may be sequentially switched to connect an output of a first pathway with different spot beams within a first beam group to establish traffic according to a first transmit beam switching pattern. At least one transmit-side switch may be sequentially switched to connect an output of the second pathway with different spot beams within a second beam group to establish traffic according to a second transmit beam switching pattern. The first and second transmit beam switching patterns may be coordinated to avoid substantial interference between traffic transmitted to a spot beam of the first beam group on a same frequency as traffic transmitted to a spot beam of the second beam group.
