<P>PROBLEM TO BE SOLVED: To solve problems that electric field strength is weakened when a dielectric substance exists in a wireless signal communication route in a wireless communication apparatus for performing communication based on wireless signals between a first apparatus and a second apparatus, and thereby it is necessary to increase transmission output and a user can not know the existence of the dielectric substance on the wireless signal communication route. <P>SOLUTION: When the existence of the dielectric substance on the wireless signal communication route and its periphery is judged from a detection result of received electric field intensity and a detection result of received magnetic field intensity in the wireless communication apparatus for performing communication based on wireless signals between the first apparatus and the second apparatus, the judged result is notified. <P>COPYRIGHT: (C)2007,JPO&INPIT |
