Classification: CPC G  H | IPC G  H

Claim 17:
18. A computer-implemented method, comprising:
receiving at least one signal measurement from a position consumer device;
using the at least one signal measurement to estimate a position of the position consumer device in a fingerprint map;
using a first threshold value to identify reference data points that are near an estimated position of the position consumer device;
using a second threshold value to filter the reference data points that are near the estimated position of the position consumer device;
selecting a pair of reference data points with associated signal measurements that bracket the at least one signal measurement from the position consumer device;
interpolating a selected pair of reference data points; and
calculating a location of the position consumer device based on geo-locations of position source devices associated with reference data points.
