First Claim
Patent Images
1. A method for updating a wireless signal model, the method comprising:
- measuring a distance from a mobile station to each wireless access point, of a plurality of wireless access points, based upon a wireless signal model;
calculating a position of the mobile station based upon the measured distance;
determining a computed distance to each wireless access point based upon the calculated position of the mobile station;
updating the wireless signal model based upon the measured and computed distances to each wireless access point; and
determining whether the wireless signal model has converged.

Abstract
An example method for updating a wireless signal model includes: measuring a distance from a mobile station to each wireless access point, of multiple wireless access points, based upon a wireless signal model; calculating a position of the mobile station based upon the measured distance; determining a computed distance to each wireless access point based upon the calculated position of the mobile station; updating the wireless signal model based upon the measured and computed distances to each wireless access point; and determining whether the wireless signal model has converged.
