Wi-Fi Positioning Goes to Moscow
I've tried Wi2Geo positioning service a few days ago—cool, it works. It pointed my location very accurate—missed just about 20 m.
Wi2Geo is a Wi-Fi navigation service. Currently it works in Moscow, but they're going to add other major Russian cities to the database. The idea is: knowing Wi-Fi access points locations (there usually a few available in most locations in Moscow city) and signal strength one can calculate Wi-Fi device location.
I have been using Windows client on my notebook and a Windows Mobile one on iPAQ 514—both successfully displayed my location. Symbian and iPhone should be supported in the future too.
As for today, Wi2Geo is aware about 16 thousands APs, mostly in the city center, and counting. Wi2Geo is going to have many more Wi-Fi networks in database by the public service opening in July, 7th. It is possible to browse through all known APs on the map on a Wi2Geo website (only 100 are shown, zoom in to see more), open networks, private networks and Golden WiFi broadband are displayed in different colors.
Of course, there are some social stuff also. The service displays friends locations, and the developers are promise to add a nearby cafes lookup and a possibility to publish user's movements on the web. A service API would be published after opening.
