Performance evaluation of wearable passive RFID tag for human indoor positioning

This paper proposes a solution for human indoor positioning utilizing the embroidered passive Radio Frequency Identification (RFID) tag. The performance of the on-body RFID tag for indoor positioning applications is compared with the existing Wireless LAN solutions. As a proof of concept, we conducted both training and positioning phase of the fingerprinting method which relies upon the measurement of the Received Signal Strength (RSS) of the RFID tag and the WLAN access points (APs). The comparison of RFID with WLAN results shows very valuable achievements utilizing RFID technology in term of the accuracy especially for small distance error.
