摘要 |
<P>PROBLEM TO BE SOLVED: To prevent radio interference by recognizing interference between data reading devices as well as interference between the data reading device and a radio IC tag. <P>SOLUTION: A radio communication system is provided with a plurality of data reading devices 2 which perform data communications with the radio IC tags, and an interference information processing device 1 which acquires interference information for interference power in the data reading device 2. The interference information processing device 1 issues an instruction to measure interference power at a predetermined timing using a predetermined data communication device 2 as a measuring device. The interference information processing device 1 issues an instruction to communicate with the radio IC tag at the predetermined timing using a data communication device 2 different from the measuring device as an interference device. The interference information processing device 1 acquires interference power measured by the measuring device. <P>COPYRIGHT: (C)2010,JPO&INPIT |
