Electronic apparatus and communication control method
First Claim
1. An electronic apparatus which executes wireless communication, comprising:
- a device detection unit which detects an external device which is located within a wireless communication area that is covered by the electronic apparatus;
a distance calculation unit which calculates a distance between the electronic apparatus and the detected external device on the basis of a radio-wave intensity of a wireless signal which is transmitted from the detected external device; and
a connection control unit which establishes wireless connection between the detected external device and the electronic apparatus if the distance calculated by the distance calculation unit is within a predetermined reference distance.
