Wireless mobile communication system

摘要

The present invention aims at alleviating the load to a radio base station without degrading the performance of the radio base station and at reducing the costs of a system as a whole. In a wireless mobile communication system according to the present invention, an array antenna including element antennas (3a), (3b), ..., (3n) is employed as a radio base station antenna (3), and a signal to be fed to the antenna in accordance with the position of a mobile station or data necessary to generate the signal is transmitted from the control station (1) to the radio base station antenna (3) so as to change the directivity of the radio base station antenna (3) in adaptation to the traveling of the mobile station for communications between the radio base station and the mobile station. <IMAGE>
