Abstract
A method and system for locating tires is disclosed. According to the invention, an RFID reader antenna is positioned at a predetermined location such that the distances between the reader antenna and the tires are different. Each tire embeds at least one RFID tag. The distance between the reader antenna and each RFID tag is determined by measuring the delay required for the signal to be reflected by the RFID tag. Since all the distances between the reader antenna and the RFID tags are predetermined, knowing the distance between the reader antenna and a particular RFID tag allows the determination of the position of the particular RFID tag and of the tire.
