Fu, Z., Crisp, M., Yang, S., Penty, R., & White, I. (2017). Long distance passive UHF RFID system over ethernet cable. 2017 IEEE International Conference on RFID Technology and Application, RFID-TA 2017, 294-298. https://doi.org/10.1109/RFID-TA.2017.8098865
This paper proposes a new antenna remoting system for ultra-high frequency (UHF) radio frequency identification (RFID). The system consists of a central baseband controller and a remote antenna subsystem, which are connected using twisted-pair cable. During the inventory session, only baseband signals are transmitted over the twisted-pair cable, whilst the transmitted radio frequency (RF) signals are up and down converted in the antenna subsystem. This new RFID system provides -94.5 dBm of reader sensitivity, and can fulfill long-distance detection tasks with very low performance degradation over up to 150 m of Cat5et cable. Compared with conventional RFID systems using coaxial cables between reader and antenna, the presented RFID system is more flexible and cost-efficient due to its low deployment cost and ease of cable routing.
