ABSTRACT:
A method and apparatus for preventing radio communication system access by an unauthorized modem. The apparatus comprises a signal detector that determines if an authorization signal has been received from the base station within a specified period of time. The authorization signal authorizes the apparatus to communicate with the base station. A transmitter transmits information to the base station, and a controller disables the transmitter of the apparatus providing that the authorization signal has not been received within the specified period of time.
