Title:

METHOD OF ASSIGNING AND DEDUCING THE LOCATION OF ARTICLES DETECTED BY MULTIPLE RFID ANTENNAE

Document Type and Number:

WIPO Patent Application WO2005111959

Kind Code:

A3

Abstract:

In accordance with preferred embodiments of the invention, a method and corresponding apparatus is provided for deducing the location (342, 344) of one or more items or objects (326) to be monitored. In exemplary embodiments, the method and corresponding apparatus is implemented in RFID (radio frequency identification) applications (e.g. reading RFID tags at 13.56 MHz and approximately 900 MHz) by deducing the location of an item associated with a unique RFID tag (118) in one or more areas of detection (314, 324) covered by multiple RFID reader antennae (110, 120).
