 This allows a comparison with the optimized \docAPshort{} positions. 
 Within all Wi-Fi observations, we only consider the beacons, which are identified by their well-known MAC address. 
 Other transmitters like smart TVs or smartphone hotspots are ignored as they might cause estimation errors.

+Fig. compares optimized ap vs real positions for the ground level, thus we only illustrated optimized ap', which are really installed there. red created using the global optimization scheme, blue a optimized only for the rechteckigen ground floor.
