WIRELESS COMMUNICATION DEVICE
First Claim
1. A wireless communication device that carries out wireless communication using a short-range wireless communication method having a ranging function, the wireless communication device comprising:
- a ranging unit which determines distances to other wireless communication devices within a wireless communication distance using the ranging function;
an identification unit which, using the determined distances, identifies a communication device from among the other wireless communication devices as an identified other wireless communication device with which a wireless connection is to be established;
a control unit which establishes wireless connection with the identified other wireless communication device; and
a data transmission unit which carries out data transmission using the wireless connection,wherein the ranging unit determines the distance to the identified other wireless communication device with which the wireless connection is established and the control unit disconnects the wireless connection if the distance to the identified other wireless communication device satisfies a predetermined condition.

Abstract
A wireless communication device for effecting wireless communication using a short-range wireless communication method having a ranging function, which carries out wireless connection establishment/disconnection control using ranging information. For example, the wireless communication device determines the range to another wireless communication device within wireless communication range, and if it finds a wireless communication device present within a predetermined range establishes a wireless connection with that wireless communication device, and disconnects the connection if the wireless communication device with which the device is in wireless connection passes beyond a predetermined range.
