A team of Stanford University researchers have developed a small Wi-Fi device that behaves similarly to a radio frequency identification tag, sending a unique identifier that indicates where it is located, but doing so via Wi-Fi access points without impacting the Wi-Fi network where the tag is located. The solution, known as HitchHike, consists of a small tag—which could cost the same as an ultrahigh-frequency (UHF) RFID tag—as well as standard...
