Evaluating the suitability of specific RFID tags for IoT applications through a new characterization platform

Radio-frequency identification (RFID) is one of the most promising technologies to enable new smart applications in the framework of the Internet of Things (IoT). Nevertheless, from the electromagnetic point of view, the performance of the RFID tags is generally dependent on the context, so that the selection of the most suitable tag for the specific application becomes the key point. In this work, a cost-effective but accurate characterization system for the performance evaluation of UHF RFID tags is first presented and then validated on the IoT-related relevant case of RFID-based interaction with buildings.
