Study Defines RFID System Capacity, Sets Performance Metrics for Gen-2 Protocol

Engineering researchers at the University of Arkansas have developed a novel mathematical model that describes how radio-frequency-identification (RFID) readers capture tag data on a single inquiry. The researchers – Kazem Sohraby, professor of electrical engineering, and Chonggang Wang, post-doctoral fellow in the department of electrical engineering – also developed two critical performance metrics to measure capacity of a single RFID reader environment.
