Most indoor location positioning systems rely on Wi-Fi signals - they look at the set of Wi-Fi hotspots that are in range of the phone, and how strong the signals are for each one, and use a database of hotspot locations or a collection of "signal strength fingerprints" to estimate the phone's current location. This is how must indoor location systems on the market work, including Google's. But here's the rub: iPhone's iOS doesn't let apps have the Wi-Fi signal strength data. Many people have speculated why, and I suspect the reason is that they want to keep indoor positioning all to themselves. It's unfortunate, because Apple of all people should know that they win a lot by supporting 3rd-party developers on iOS. But that's how it is. Two weeks ago we reported the first deployment of a new approach to indoor location , by SenionLab , using sensors in the phone (gyroscope, compass, accelerometer, ...) to detect phone movements and track ...
