Abstract
The present invention provides a mobile radio telephone system (10, 15) and a method of operating it in which the beacon frequency is at least temporarily transmitted in a discontinuous manner. This allows a base transceiver station (2, 4, 6, 16, 20, 22) to make use of the gained time for either transmitting on another frequency or monitoring neighboring radio frequency sources for potential interference.In a particular embodiment of the present invention, the beacon frequency is interrupted by connecting the transmission path to the receiver path within the base transceiver station (2, 4, 6, 16, 20, 22). This may be done by single pole double throw high frequency switches. The interruption may be temporary or may applied permanently.Further, in a system in which all transmissions by the base transceiver stations (2, 4, 6, 16, 20, 22) are synchronized, mobile stations (12) are described which are adapted to measure signal strength depending upon the duty cycle of the beacon frequency.
