<P>PROBLEM TO BE SOLVED: To provide a technology which eliminates limitation of degree-of-freedom of installation of a radio communication system due to existence of a reflection object. <P>SOLUTION: A radio communication system, in order to communicate with a radio device in space where a reflection object exists, radiates an electromagnetic wave at least two different conditions: a first condition and a second condition. In order to communicate with a radio device in a null region caused by interference between a direct wave and a reflection wave by a reflection object of an electromagnetic wave with the first condition, the radio communication system radiates an electromagnetic wave with the second condition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
