All over the place
I’m doing some work with location based services at the moment. A colleague told me of some of the problems they had had with the software. One was related to the SkyHook system. This is the system that Apple used and helps to improve the speed of acquiring a fix by mapping the location of Wifi hotspots and cell towers.
the app would for the most part correctly report the position but during field testing- say when heading down the M25 – it would occasionally report the location as being back in central London. This erratic behaviour was a bit of a puzzle to the the engineers until they discovered that National Express have been installing Wifi access points on their buses.
