DATA TRANSFERRING SYSTEM, WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION METHOD, AND COMPUTER PROGRAM

Document Type and Number:

WIPO Patent Application WO/2007/020912

Kind Code:

A1

Abstract:

A method for determining, by use of less information bits, a communication apparatus that is recognized by a nearby communication apparatus in an ad hock network. Each of a mobile device and a cradle incorporates a UWB radio apparatus. While the mobile device is housed in the cradle, the antennas of the UWB radio apparatuses are fixed in such attitudes that their directivities of electromagnetic wave face each other and in such a manner that they are in a very close range independent of the surrounding environment. When the mobile device is housed into the cradle and then the distance-measuring functions of the UWB radio apparatuses are used to determine that the apparatuses enter into a predetermined distance range, an operation of wireless data transmission is initiated, thereby achieving a high-rate, high-quality transmission.
