I suppose to have a high degree of accuracy, they'll need to have the coordinates of every public Wi-Fi to triangulate from.
Which brings another question.. how to identify a unique Wi-Fi router? Via a MAC address? That's an intensive task by itself.
I foresee... Router manufaturers rolling out firmware to place lat/long information for the routers to broadcast (along with their name, ID, etc...)
Hmmm....
Geolocation is the future. And here's my lat/long: 1.327797,103.859749
I wonder what they'll call the vertical coordinate. The z-axis. Azimuth? My router's placed approximately 18 metres above ground. I should calculate how much that is in local sea level.
Wait. Didn't I study this already?
