Abstract
Recently UHF RFID system has drawn a great deal of attention because of its potential to revolutionize supply chain management. In this article, RFID reader-to-reader interference is analyzed in terms of interrogation range. For evaluating RFID interference quantitatively, the new figure-of-merit, IRRR, is defined. In order to show the usefulness of IRRR, calculated IRRR is verified by measurement using two RFID readers and a tag in multiple-reader environment. IRRR can be referred to an important design parameter to analyze more complex interfering problems in actual RFID system deployments.
