  • Base station transceiver diagnostic equipment
    Patent number: 5471649
    Abstract: Base Station Transceiver Equipment 10 is provided such as for use in a cellular radio telephone system. In a first aspect of the invention, a device within the equipment measures a parameter (e.g. timing, signal strength) of a mobile transceiver and instructs the mobile to adjust that parameter of its transmitted signals. Subsidiary transceiver equipment 11 (a diagnostic sub-system or "test mobile") is provided in relative proximity to the base station transceiver equipment. The subsidiary equipment can change the parameter of its transmissions to simulate relative distance from the base station transceiver equipment for test purposes. In other aspects of the invention, a device is provided for testing the base station antenna.
