Abstract: Terminating or otherwise preventing communications in a predefined quiet zone by imposing a time delay. In one embodiment an existing call is terminated during a transition between two wireless access points by imposing a time delay on communications through one of the access points. The time delayed signal is interpreted as noise and causes a base station to drop the call if the noise causes the signal strength from the other access point to fall below a threshold. Within a quiet zone, a signal time delay prevents a client device from responding to a base station connection instruction, which causes the base station to believe that the client device is out of range of a quiet zone access point. The time delay may be imposed by an optical fiber spool between the quiet zone access point and the base station, or other delay mechanism. One embodiment is aboard a vessel.

Abstract: Embodiments are directed to avoiding interference between a maritime mobile radio network and a mobile radio network provided at a fixed position relative to the maritime mobile radio network. A current geographic position of the maritime network is determined. A minimum separation distance to be maintained between the two networks is determined based on the geographic position. A current separation distance is predicted based a signal detected from the fixed-position network. When the predicted separation distance is less than the minimum separation distance and the detected signal is determined to be persistent, the maritime network is turned off. The detected signal may be determined to be persistent when it is continuously detected over a predetermined time period and has sufficient signal energy for sustaining a cellular telephone call.
