ABSTRACT:
A system and method for controlling the strength of a shared resource signal transmitted by the satellite transponder in a satellite communications system. The satellite communications system includes a gateway for transmitting communications signals including a shared resource signal, a satellite transponder for relaying the signals to at least one subscriber unit (for example, a phone), and at least one subscriber unit for receiving the signals. The method includes the steps of receiving the shared resource signal, at each subscriber unit, via the satellite transponder; measuring, at each subscriber unit, a signal strength for the received shared resource signal; sending the signal strengths to the gateway; and adjusting the power of the shared resource signal transmitted by the satellite transponder based on the signal strengths.
