ABSTRACT:
A method and system for verifying that each remote cell unit in a cellular phone system is operational. The system and method in accordance with the present invention use the receiver equipment of each cell unit to listen to or monitor transmissions by other cell units. Each cell unit is independently placed in a listen verification mode in which it measures communication quality of other cell units that it can hear. The selected cell unit reports the communication quality results to a master control unit. The master control unit stores the result information to allow a comparison of communication quality over time. If communication quality has degraded over time by a significant amount, the master control unit signals an alarm. In another aspect of the present invention, the listen verification mode can be used during installation of the cellular system to verify performance of the system and adjust the system for optimal performance.
