Hi,<br><br>WiFi triangulation = kismet built database of Wifi hotspots.<br>Triangulation algorithm is well known and already implemented in cell phones for<br>base station tower triangulation.<br><br>Are you aware what patents have been granted in this area ?<br><br>" from webpage"<br>http://www.skyhookwireless.com/press/skyhookapple.php<br><br>"The patented technology behind WPS leverages that database to provide location information.
