<P>PROBLEM TO BE SOLVED: To reduce the deterioration in quality during telephone conversation or during communication as much as possible without causing malfunctions and the like. <P>SOLUTION: An antenna setting part 5-1 sets a threshold E0 for a reception electric field intensity. An antenna determination part 5-2 determines whether or not an electric field intensity at an antenna for an original wireless function is larger than the threshold E0, which is set by the antenna setting part 5-1, based on a detection result from an electric field intensity detector 1. In the case that the electric field intensity at the antenna for the original wireless function is larger, the communication is continued without performing antenna switching by antenna switching parts 2-1 and 2-2. On the other hand, in the case that the electric field intensity at the antenna for the original wireless function is lower and an electric field intensity at an antenna for the other wireless function is larger, or alternatively in the case that a total electric field intensity at antennas for a plurality of wireless functions is larger, the antenna determination part 5-2 performs switching of antennas #1-#4 by the antenna switching parts 2-1 and 2-2, and continues the communication. <P>COPYRIGHT: (C)2012,JPO&INPIT |
