US Patent 8175577 Non-jamming security zone access control for mobile communication devices

A security zone monitoring system in cooperation with a wireless communication system may control access to the wireless communication system by mobile communication devices while near or within a security zone. The wireless communication system may include a security communication system which may receive communications from the security zone monitoring system indicating the identity of each mobile communication device which has been detected and whether the mobile communication device is near or within the security zone. The wireless communication system may include a security information processing system which may disrupt access to the wireless communication system by each mobile communication device in ways which differ depending on whether a communication from the security zone monitoring system indicates that the mobile communication device is near or within the security zone.
