  • Method and system for location estimation
    Patent number: 9510319
    Abstract: Several methods and systems for location estimation are disclosed. In an embodiment, the method includes performing a primary wireless scan to identify a first set of access points at a user location associated with a first user location estimate. A secondary wireless scan is performed at pre-defined time intervals subsequent to the primary wireless scan. A set of access points is identified corresponding to each secondary wireless scan. The method further comprises detecting a presence or an absence of user motion based on a number of shared access points between the first set of access points and a set of access points corresponding to each secondary wireless scan. A current user location is estimated to be the first user location estimate if the user motion is detected to be absent, or a second user location estimate computed based on geolocation signals if the user motion is detected to be present.
