Currently, mobile phones are the primary method of navigation. However, indoor positioning and navigation poses a unique problem because the Global Positioning System (GPS) satellites normally used to navigate oudoors have limited use indoors. One solution is using Wifi access points as anchors, measuring the signal strength and calulating position using trilateration. Indeed, there are tools t...
