Appendix "Office" shows the possibilities of positioning systems in premises, built in almost any modern mobile phone, on the example of a pilot zone, located on the 10 floor of the central office. Navigation through the room is built using the fixed network beacons transmitting signals bluetooth low energy. Annex on the strength of these signals using trilateration algorithm, as well as other available sources of data, for example, the testimony of the built-in accelerometer in the phone determines the location of the phone in real time.
In Scheme floor marked involved in the pilot operation of the point of interest. Before each of these points you can build a route from the current position of the phone.
