To provide a wireless communication system capable of enhancing communication quality by developing a high gain characteristic of a variable directivity antenna without complicating the configuration of a fixed directivity communication station, improving the communication quality from the fixed directivity communication station to a variable directivity communication station, and operating communication stations without the need for changing the configuration and the settings of each communication station even when the number of the communication stations is increased.

In the case of carrying out wireless communication between the variable directivity communication station whose antenna directivity is changed and the fixed directivity communication station whose antenna directivity is not changed in the wireless communication system, the variable directivity communication station sequentially and repetitively scans the directivity direction of a directive beam synchronously with time, and the fixed directivity communication station 20 detects a timing when the directivity beam from the variable directivity communication station is directed in the station 20 and carries out the wireless communication in the timing.
