PROBLEM TO BE SOLVED: To provide a wireless communication device which supports three or more types of wireless communication methods and controls the effect of radio interference to wireless communication methods related to real-time data transmission and reception. SOLUTION: If it is determined that data which is transmitted and received through WLAN wireless communication 200 can be also transmitted and received through BT wireless communication 400 during DCL wireless communication 500 (S26:Yes), a switching request signal is transmitted to a PC 61 to request the data transmission and reception by switching from the WLAN wireless communication 200 to the BT wireless communication 400 (S27). The BT wireless communication 400 and the DCL wireless communication 500 are performed by a frequency hopping method, so that the possibility that radio interference occurs between them is decreased. Thereby, the effect of radio interference due to data transmission and reception can be reduced in the DCL wireless communication 500. COPYRIGHT: (C)2009,JPO&INPIT
