Patent ID: 8144654

Claim:
A communication device communicating with a first communication device and a second communication device, the communication device comprising: a first communicating unit capable of communicating wirelessly with the first communication device according to a first communication method; a second communicating unit capable of communicating wirelessly with the second communication device according to a second communication method different from the first communication method; a first frequency setting unit setting a first frequency band used for wireless communications by the first communicating unit, the first frequency band providing a first center frequency; a second frequency setting unit setting a second frequency band used for wireless communications by the second communicating unit, the second frequency band providing a second center frequency; a selector selecting whether to shift the second frequency band; and a control unit controlling the second frequency setting unit to set the second frequency band so as to provide overlapping of the first center frequency with the second center frequency when the selector selects to shift the second frequency band, wherein when the second frequency setting unit sets the second frequency band so as to provide overlapping of the first center frequency with the second center frequency, the first communicating unit communicates with the first communication device according to the first communication method by using the first frequency band and the second communicating unit communicates with the second communication device according to the second communication method by using the second frequency band whose center frequency is overlapped with the first center frequency.
