要約(日本語): This paper has proposed a link analysis based device free localization method of RFID tags using a drone having horizontally oriented metallic wound wire. The proposed wire structure enabled the drone to shadow the radio wave propagation links between RFID tags and an RFID reader, while keeping the drone stable. This is because the wire is wound around the drone and then it did not affect to the air flows generated by propellers. To validate the possibility of the proposed localization method, horizontally polarized RFID tags are placed on a wall of a corridor and a drone operator flied the drone nearby RFID tags. Time series RSSI values were acquired by a RFID reader radiating 250 mmW circularly polarized radio waves. The proposed drone successfully caused decreases of RSSI values when the drone flied nearby RFID tags. These results preliminary confirmed that the drone with wound metallic wire enables a link analysis based device free localization of RFID tags.
