  • System and method for location recognition using ic tags
    Publication number: 20070103301
    Abstract: Locations of IC tags affixed to items are automatically recognized without requiring interrogators or antennas are allocated at respective inventory locations. To attain this object, interrogator 1 firstly transmits a unique ID readout command specifying read range, and corresponding IC tags 2a, 2b, 2c sequentially reply their unique IDs (Xa), (Xb), (Xc) respectively. At the same time, interrogator 1 transmits a probe signal send out command specifying ID, and corresponding IC tags 2a, 2b, 2c sequentially send out probe signals respectively. IC tag 2 that detects a probe signal with reception strength more than a predetermined level stores in its memory IDs (Xa), (Xb), (Xc) that interrogator 1 specified as adjacent ID. Then, interrogator 1 transmits an adjacent ID readout command specifying ID, and corresponding IC tags 2a, 2b, 2c sequentially reply adjacent IDs (Xb), (Xa.Xc), (Xb) stored in their memory respectively.
