RFID TAG PARAMETER DETERMINATION USING PHASE

RFID tag reply phase measurements can be used to estimate tag location and motion. The phase measurements can be used to directly calculate tag location/motion or to generate correlation probabilities with candidate tags having different location motion characteristics. An RFID reader system can tak...

More Information
Summary:RFID tag reply phase measurements can be used to estimate tag location and motion. The phase measurements can be used to directly calculate tag location/motion or to generate correlation probabilities with candidate tags having different location motion characteristics. An RFID reader system can take multiple phase measurements for a tag, at different carrier frequencies, within a single inventory round, to ensure that the tag remains within range of the reader system.
