<P>PROBLEM TO BE SOLVED: To perform efficient radio communication while suppressing radio interference between radio parts. <P>SOLUTION: A radio device 3 performs radio communication with a base station by a TDD system part 4 and performs radio communication with a terminal by a wireless LAN part 5 to intermediate between the terminal and the base station. A measurement part 41 measures radio interference due to an electric wave transmitted from an antenna 56, for example, by the intensity of an electric wave received by an antenna 46. A measurement part 51 measures radio interference in the same manner. A determination part 31 receives measured values from the measurement part 41 and the measurement part 51 to determine whether radio interference exceeding an allowable level occurs in at least one of measured values or not and, when determining the occurrence of the radio interference, drives an interference notification part 32 to inform a user. The radio device 3 includes the antenna 46 and the antenna 56 installed in different enclosures, and the informed user reduces the radio interference by adjusting an angle formed by two enclosures to adjust a distance and an angle formed by polarization directions between antennas 46 and 56. <P>COPYRIGHT: (C)2009,JPO&INPIT |
