Wireless Applications - Legoland Tags Kids for Safety
At its season-opening day in March, the park launched a new child-tracking system that combines RFID tags and Wi-Fi technology, according to a recent report in Network World. Visiting parents with cell phones and text-messaging capabilities can rent wireless-enabled wristbands for their kids, and then track the children to within about five feet of their location if they become separated.
At Legoland, Wi-Fi access points and location receivers scattered throughout the 2.5 million-square-foot park are set to receive Wi-Fi-compatible messages. The access points and receivers pick up Wi-Fi messages from the RFID tags (from a vendor called Bluesoft) and use triangulation to determine where a particular tag is located. Now the whole park doesn’t have to hear that your kid is missing.
