ABSTRACT:
A telecommunications device is provided that enables monitoring of the directivity of a wireless communications system that wirelessly transmits signals using multiple communications antennas while controlling the overall directivity of the multiple antennas. At least one monitor antenna, installed separately from multiple communications antennas controlled to achieve a prescribed overall directivity, wirelessly receives signals from the multiple communications antennas. A directivity information acquisition mechanism uses the signals received by the monitor antenna to acquire information regarding the overall directivity of the multiple communications antennas. The directivity information acquired by the directivity information output mechanism is output to an external achieved directivity accuracy monitoring mechanism, and the achieved directivity accuracy monitoring mechanism monitors the accuracy of achieved overall directivity of the multiple communications antennas based on a difference between the directivity information and directivity information predicted to be acquired when a prescribed directivity is achieved.
