Abstract
Disclosed are various embodiments that enable the identification of the location of a computing device based on radio data. A radio map can be identified for an area. The computing device can measure signal strengths to reference points. The signal strengths can be compared to the radio map. The computing device can determine its location based on the comparison of the signal strengths to the radio map.
Claims20
A method comprising:
- identifying a radio map for an area;
- determining a plurality of access points within the area;
- determining, via a computing device, a set of location-dependent measurements characterizing signals received from at least one of the plurality of access points;
- generating a comparison of the set measurements to the radio map based at least in part on a multi-objective optimization of at least two objective functions;
- and
- determining a position vector corresponding to a location of the computing device based at least in part on the comparison.
