Abstract. An increasing number of applications use RFID in their design, but there is a lack of understanding of how mobility affects RFID performance in these applications. Unlike static RFID experiments, mobile RFID studies require more expensive equipment that are unavailable to most researchers. In this paper, we conduct machine-aided experiments to study the effects of mobility on RFID. Our results show that up to 50 RFID tags moving at speeds up to 2 m/s can be reliably read.
