<p>Base Station Transceiver Equipment (10) is provided such as for use in a cellular radio telephone system. In a first aspect of the invention, means within the equipment measure a parameter (e.g. timing, signal strength) of a mobile transceiver and instruct 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, means are provided for testing the base station antenna.</p> |
