Wireless communication device
First Claim
1. A wireless communication device comprising:
- a wireless communication unit that (a) establishes a wireless connection between the wireless communication device and an external device located in a first area, after the wireless communication device moves toward the external device and into a second area that is smaller than and within the first area, and (b) disconnects the wireless connection between the wireless communication device and the external device, after the wireless communication device moves away from the external device and out of the first area;
a control unit that (a) controls the wireless communication device based on a first event indicating that the wireless connection between the wireless communication device and the external device has been established, and (b) controls the wireless communication device based on a second event indicating that the wireless connection between the wireless communication device and the external device has been disconnected; and
a display unit that displays information about a distance by which the wireless communication device needs to be moved to establish the wireless connection between the wireless communication device and the external device,wherein the external device is capable of determining a range of the second area.

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.
