Fig. 10From: A scalable deep neural network architecture for multi-building and multi-floor indoor localization based on Wi-Fi fingerprintingLocation coordinates estimation examples (a) with several reference points centered around a new location and (b) with only a few reference points around it, where × denotes a new location whose coordinates are to be estimated and ● denotes a reference point whose coordinates are stored in the fingerprint database. The numbers over the reference points indicate their closeness to the new location with 1 being the closestBack to article page
