Title:
RADIO COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2003/090367
Kind Code:
A1
Abstract:
It is possible to suppress reception disturbance during data transfer to a display unit or the like without using a shield structure. A radio communication device includes a data transfer bus (41) arranged between control unit (16) and a display unit (19). The data transfer bus (41) can perform data transfer all the time independently of the operation of a transmission/reception unit (12). When a downloaded program is executed in the control unit (16), data can be transferred to the display unit (19) so that operation display can be performed. The control unit (16) acquires information of a communication channel used when a mobile telephone device is connected to a base station for performing radio communication. If the frequency of the communication channel overlap with the noise caused by the data transfer and reception may be disturbed, the control unit (16) modifies the data transfer frequency, shifts the noise frequency, and suppresses the reception disturbance.
