Effects of Interferences in UHF RFID Systems

By Antonio Lazaro, David Girbau, and Ramon Villarino
Progress In Electromagnetics Research, Vol. 98, 425-443, 2009


The Radio Frequency Identification (RFID) applications are growing rapidly, especially in the UHF frequency band that is being used in inventory management. Passive UHF tags are preferred for these applications. In this paper, RFID reader-to-reader interference is analyzed. A model to estimate the minimum distance between readers to achieve a desired probability of detection in real multipath environments is derived and compared to the ideal case (AWGN channel). Diversity techniques to combat multipath and interference effects are proposed and studied.
