Geo-location signal fingerprinting
First Claim
Patent Images
1. A mobile device comprising:
- a location estimator configured to estimate a present location of the mobile device;
a signal-fingerprint manager configured to determine one or more signal fingerprints about the mobile device at that present location, wherein the determined one or more signal fingerprints are based at least in part upon a signal strength and a corresponding identification of one or more ambient identifiable wireless signal (IWS) sources;
a location manager configured to associate the estimated location with the determined one or more signal fingerprints;
a communications unit configured to send the association between the estimated location and the determined one or more signal fingerprints to a remote location-fingerprint database.

Abstract
Disclosed herein is a technology related to low-power, accurate location estimation for mobile devices (such as a smartphone). More particularly, the disclosed technology facilitates estimation of a physical or “real world” location (e.g., geo-location) without relying on the conventional always-on and battery-draining approaches of Global Positioning Systems (GPSs) or some form of telemetry based upon multiple radio signals (e.g., cellular). This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

9. One or more non-transitory computer-readable media with processor-executable instructions stored thereon which when executed by one or more processors cause performance of operations comprising:
-
estimating a present location of a mobile device; determining one or more signal fingerprints about the mobile device at that present location, wherein the determined one or more signal fingerprints are based at least in part upon a signal strength and a corresponding identification of one or more ambient identifiable wireless signal (IWS) sources; associating the estimated location with the determined one or more signal fingerprints; sending the association between the estimated location and the determined one or more signal fingerprints to a remote location-fingerprint database. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
