Abstract:
A wireless device and a communication method, which enable a position of the wireless device to be known and enable a frequency which does not interfere with that of another wireless station to be selected, are provided. A wireless device belonging to a second wireless system in which a frequency band to be used overlaps with that of a first wireless system, and a priority with which the overlapping frequency band is used is lower than that of the first wireless system, the wireless device includes: a location receiving unit receiving location information formed of a place name and indicating a location of the wireless device; a geographic coordinate acquiring unit acquiring, based on the location information, geographic coordinates including latitude and longitude corresponding to the location information; and a frequency setting unit accessing a frequency server in which a frequency assigned to a wireless device belonging to the first wireless system and geographic coordinates including latitude and longitude related to a position of the wireless device are stored by being corresponded to each other, by using the geographic coordinates acquired by the geographic coordinate acquiring unit, and acquiring at least one of a frequency that is not assigned to the wireless device belonging to the first wireless system and a frequency which is not at risk of interfering with that of the wireless device, to set the frequency as a transmission/reception frequency.
