A company called Skyhook Wireless announced a nifty service for using Wi-Fi access points to locate a user in a manner similar to GPS. By assessing the relative strength of broadcast beacons from known Wi-Fi access points the service can pinpoint a user's location. While similar to GPS, it doesn't have quite the accuracy — and it requires an appropriate level of Wi-Fi density so its use is limited to urban areas. Still, they've identified several potential markets for the technology, and I'm hoping they find some buyers for this very novel use of Wi-Fi.
