Abstract:
1. A satellite radiotelephone system comprising: a space-based component configured to provide communications using frequencies of a satellite frequency band; and a plurality of ancillary terrestrial components configured to provide communications over a service region using at least one first frequency of the satellite frequency band in a sectorization pattern that is spatially staggered between ancillary terrestrial components, wherein the space-based component excludes communications using the at least one first frequency over the service region and an aggregate power radiated by the plurality of ancillary terrestrial components at the at least one first frequency in any direction is less than a total power radiated by the plurality of ancillary terrestrial components at the at least one first frequency; wherein the sectorization pattern is spatially staggered so that each one of the plurality of ancillary terrestrial components transmits the at least one first frequency in a respective different direction.
