<P>PROBLEM TO BE SOLVED: To provide a superior data transfer system in which wireless transmission of massive data, such as images and music, can be carried out mutually at high speed, with consumer devices being located in ultra-short distance by using UWB communication system, and a wireless communication apparatus and a wireless communication method, and a computer program. <P>SOLUTION: UWB wireless devices are mounted on both sides of a mobile device and a cradle. In a state with the mobile device contained in the cradle, securing connection is performed, in an attitude which directivity of mutual electromagnetic waves of the antennas of the UWB wireless devices face each other and in ultra-short distance, independently of the peripheral environment. When the device is contained in the cradle, if the devices detect themselves, having entered inside a predetermined distance by the range finder ability of the UWB wireless devices, wireless data transmission operation is initiated, and high transmission rate as well as high quality transmission can be realized. <P>COPYRIGHT: (C)2007,JPO&INPIT |
