Systems and methods for monitoring terrestrially reused satellite frequencies to reduce potential interference
First Claim
1. A satellite radiotelephone system comprising:
- a space-based component that is configured to wirelessly communicate with a plurality of first radiotelephones in a satellite footprint over a satellite radiotelephone frequency band;
an ancillary terrestrial network that is configured to wirelessly communicate with a plurality of second radiotelephones in the satellite footprint over at least some of the satellite radiotelephone frequency band to thereby terrestrially reuse the at least some of the satellite radiotelephone frequency band;
a monitor that is configured to monitor wireless radiation by the ancillary terrestrial network and/or the plurality of second radiotelephones at the space-based component; and
a controller that is configured to adjust the radiation by the ancillary terrestrial network and/or the plurality of second radiotelephones in response to the monitor.

Abstract
Radiation by an ancillary terrestrial network, and/or satellite radiotelephones that communicate therewith are monitored and controlled, to reduce and preferably prevent intra-system interference and/or interference with other satellite radiotelephone systems. In particular, a satellite radiotelephone system includes a space-based component that is configured to wirelessly communicate with first radiotelephones in a satellite footprint over a satellite radiotelephone frequency band, and an ancillary terrestrial network that is configured to wirelessly communicate with second radiotelephones in the satellite footprint over at least some of the satellite radiotelephone frequency band, to thereby terrestrially reuse the at least some of the satellite radiotelephone frequency band. Wireless radiation by the ancillary terrestrial network and/or the second radiotelephones at the space-based component is monitored, and the radiation by the ancillary terrestrial network and/or the plurality of second radiotelephones is adjusted in response to the monitoring. Intra-system interference and/or interference with other satellite systems thereby may be reduced or prevented.
