PROBLEM TO BE SOLVED: To enable stable data communication without influenced by a particular radio wave.SOLUTION: In an access point performing data communication by space division multiplexing signals transmitted and received in a plurality of transmission/reception units 140-170 through a plurality of streams with a MIMO method, a radio wave environment is monitored, and when high-level interference waves 310, 320 are detected, the number of streams is set to be 1. Then the communication bands and the frequencies of the transmission/reception units 140-170 are modified in such a manner that the communication bands and the frequencies of the transmission/reception units 140-170 do not overlapped with the frequencies of the interference waves 310, 320. |
