<P>PROBLEM TO BE SOLVED: To make it possible to immediately perform network connection based on an ad hoc mode when an infrastructure mode is automatically switched to the ad hoc mode and to achieve power saving. <P>SOLUTION: A cellular phone 100 acquires a surrounding radio wave condition through a radio LAN communication circuit 109 and judges whether the surrounding radio wave condition acquired by a control part 108 is in a position range based on a preset radio wave condition or not. When the acquired surrounding radio wave condition is in the position range based on the preset radio wave condition, the cellular phone 100 starts radio communication based on the ad hoc mode between terminals in the position range based on the preset radio wave condition through the radio LAN communication circuit 109. <P>COPYRIGHT: (C)2009,JPO&INPIT |
