Method or Process

Terrestrial mobile wireless network capacity may be maximized subject to an interference constraint imposed by a protected station of another wireless network in a shared band. Equipment of one or more users (UEs) may receive a calibrated beacon signal from the protected station prior to activating a transmitter of one or more wireless UEs. The one or more UEs may measure an isolation (path loss) value between the one or more UEs and protected station using the beacon signal, and dynamically adjust the transmit power of one or more wireless UEs to maintain aggregate interference received by the protected station below an "acceptable" value. The transmit power may be adjusted based on the measured isolation and based on the indicated receive activity, such that the wireless network may operate with no interference constraints imposed by the protected station when a non-active state is indicated.
