Abstract
Locating mobile devices based on a junction of signal tiles is disclosed herein. Mobile devices are mapped to a convex hull within which the mobile device is likely to be located in based on a received signal strength indicator (RSSI) associated with an access point (AP). Using the RSSI from a set of APs, the mobile device can be located within a junction of a set of convex hulls, or tiles using a linear programming function. To mitigate signal noise and improve the accuracy of the location determination, the localization system can use the RSSIs of the APs that have signals with a predetermined signal dynamic range that leads to smaller tiles. Additionally, the localization system can reduce the search complexity of matching fingerprints to APs by partitioning the space into clusters with reference points that have similar signal vectors.
