Experimental Study on RFID Performance Factors of Conveyor Belt System Using DOE Methodology

This paper investigates how the performance factors affect RFID (Radio Frequency Identification) system performance. We focus on the following parameters: tag placement, angle of reader antenna and conveyor speed. We use commercial RFID reader and tags in experiments and DOE methodology to access the effect of different factors. Experiment result shows that tag placement, angle of reader antenna and the interaction between them have main effect on read performance. Specifically, we find that it's not true that the slower conveyor moves, the higher read rate gets. Moreover, when we set the angle of reader antenna at 15 degrees, we get maximum average read rate overall.
