There is provided a wireless communication method and an information processing apparatus capable of preventing interference from occurring between different wireless communication modules such as a wireless LAN module and a Bluetooth (BT) module when different wireless modules using the same frequency band are stored and used in the same apparatus. The Bluetooth (BT) module 24 secures a frequency band used by the wireless LAN module 23 in case of communicating with other apparatus such as a headset for IP telephone not shown, and then communicates by using a frequency of channel available in the other frequency region other than the frequency band. The BT module 24 transmits channel information of the secured frequency band used by the wireless LAN module 23 to the wireless LAN module 23. In case of directly communicating with the other information processing apparatus 22 such as PDA, when the wireless LAN module 23 receives the used channel information, the wireless LAN module 23 communicates with the other information processing apparatus 22 by using a channel of the band informed from the BT module 24.
