There is provided a wireless communication apparatus, which is capable of suppressing a burst noise emitted due to data transfer during wireless communication, thereby enhancing communication quality. The wireless communication apparatus transmits and receives a speech signal using a radio wave. Data to be displayed on the display screen is stored in a storage device. The stored data is transferred to the display device. Data displayed on the display screen of the display device is periodically updated based on the transferred data. A CPU monitors a wireless communication state of the wireless communication apparatus and stops the data transfer based on the monitored wireless communication state.
