We present a simple system to help people navigate inside of buildings or even in outside areas close to buildings. It is based on the "RSSI" and "Transmit power" data of an established Bluetooth link. The system is in principle sufficient for the intended application (pedestrian, indoor), but it is certainly not a high resolution indoor location system. The achievable accuracy is dependent on the setup (number of access points and their constellation and available Bluetooth devices) but will not be better than in the order of several meters. A main feature of this fingerprinting-like system is the representation of the estimated position in the form of probability density functions.
