<p><P>PROBLEM TO BE SOLVED: To provide a communication device that can enlarge a communicable region as well as prevent a communication error accompanying movement of the communication device. <P>SOLUTION: A communication device performing radio communication comprises: a movement detection part detecting movement of the communication device; and a communication part. When the movement detected by the movement detection part is smaller than a threshold and the radio communication with another communication device can be performed with a first communication intensity, the communication part performs the radio communication with the other communications device. When the movement detected by the movement detection part is smaller than the threshold and the radio communication with the other communication device cannot be performed with the first communication intensity, the communication part does not perform the radio communication with the other communication device. When the movement detected by the movement detection part is equal to or larger than the threshold and the radio communication with the other communication device can be performed with a second communication intensity, the communication part performs the radio communication with the other communication device. When the movement detected by the movement detection part is equal to or larger than the threshold and the radio communication with the other communication device cannot be performed with the second communication intensity, the communication part does not perform the radio communication with the other communication device. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
