<p>A mobile communication system designed to quickly recover from radio disturbances which frequently are experienced in a communication device mounted on a mobile unit. The mobile communication system is provided with an antenna for transmitting and receiving an electromagnetic wave, a tracking device for adjusting the orientation of the antenna to a direction from which an electromagnetic wave arrives, a receiving device for demodulating a received electromagnetic wave, a transmitting device for modulating information, which is to be transmitted, to an electromagnetic wave, a handset for displaying information to a user and for receiving an instruction from a user, and a control unit for controlling the tracking device, the receiving device, the transmitting device and the handset. The control unit forming the heart of this system has a countermeasure device, a display unit and a fault inferring device. A determination of a cause of radio interference is performed by monitoring the variation in the signal level of a received signal and is based on a pattern of the obtained variation.</p> |
