WIRELESS COMMUNICATION DEVICE
First Claim
1. A wireless communication device for conducting communications with an another wireless communication device, the wireless communication device comprising:
- a short-range wireless communication unit that establishes a short-range wireless communication link with the another wireless communication device, and communicates data through the short-range wireless communication link;
a sonic wave transmission unit that transmits a sonic wave for detecting a position of the another wireless communication device, after the short-range wireless communication link is established; and
a communication control unit that obtains a distance to the another wireless communication device from a time period between the transmission of the sonic wave and a receipt of a reply to the transmission of the sonic wave transmitted by the another wireless communication device, and controls the short-range wireless communication unit to start communicating data when the distance is equal to or less than a predetermined value.
