<P>PROBLEM TO BE SOLVED: To provide a mobile identification apparatus and a mobile identification method to control an increase of circuit scale and to use an inexpensive frequency hopping system while minimizing a radio wave interference in building a system in an adjacent area. <P>SOLUTION: Identification objects 5a, 5b and 5c are provided with responders 4a, 4b and 4c each, an interrogator 3a is connected to a hopping control device 7, the hopping control device 7 is connected to a host computer 1a to manage the interrogator 3a, the interrogator 3b is connected to the hopping control device 7 and the host computer 1b, the interrogator 3c is connected to the hopping control device 7 and the host computer 1c, and a set-up space 20a between the interrogators 3a and 3b and the set-up space 20b between the interrogators 3b and 3c are set so that a hopping channel interval (frequency interval) is suited to an existing frequency at the same time as each interrogator operates. <P>COPYRIGHT: (C)2007,JPO&INPIT |
