To provide a wireless communication device that can suppress increase in load of processing of changing the frequency to be used for a communication signal in order to avoid interference even when a signal in a frequency band overlapping with the frequency band of the signal to be used for communication coexist.SOLUTION: A wireless communication device 100 includes: a first communication unit 1 for performing wireless communication with a first communication signal; a second communication unit 2 for performing wireless communication with a second communication signal whose frequency band overlaps with that of the first communication signal; a third communication unit 3 for performing wireless communication with a third communication signal whose frequency band overlaps with those of the first communication signal and the second communication signal; and a first control unit 4 for controlling to change a first channel 11 of the first communication signal. The first control unit 4 is configured to acquire information on a second channel 21 of the second communication signal and information on a third channel 31 of the third communication signal, and also control to change the first channel 11 based on the acquired information on the second channel 21 and the acquired information on the third channel 31.SELECTED DRAWING: Figure 2 【課題】通信に用いる信号の周波数帯域と重なる周波数帯域の信号が混在する場合でも、干渉を回避するために、通信信号の使用周波数を変更する処理の負荷が増加することを抑制することが可能な無線通信装置を提供する。【解決手段】この無線通信装置１００は、第１通信信号により第１通信部１と、第１通信信号と周波数帯域が重なる第２通信信号により無線通信を行う第２通信部２と、第１通信信号および第２通信信号と周波数帯域が重なる第３通信信号により無線通信を行う第３通信部３と、第１通信信号の第１チャネル１１を変更する制御を行う第１制御部４とを備え、第１制御部４は、第２通信信号の第２チャネル２１の情報および第３通信信号の第３チャネル３１の情報を取得するとともに、取得した第２チャネル２１の情報および第３チャネル３１の情報に基づいて、第１チャネル１１を変更する制御を行うように構成されている。【選択図】図２
