System and methods for obtaining coarse location for a mobile device
First Claim
1. A mobile device comprising:
- one or more interfaces for detecting location reference nodes in view of the mobile device; and
a client module to send a location query to a location database, the location query comprising node data identifying the location reference nodes in view of the mobile device,wherein the client module to receive positioning information for providing a coarse location of the mobile device from the location database in response to the location query, the positioning information based on correlated position data and node data received from one or more client devices having Global Positioning System (GPS) position determination capability and configured to report position data and node data for location reference nodes in view, a probabilistic weight applied to the positioning information based on a type of radio used within each location reference node in view, wherein the mobile device is configured to display a map in response to the positioning information and to accept user input to the map, the user input is sent to the location database for adjusting the positioning information.

Abstract
Various embodiments are described for obtaining coarse location for a mobile device. In one embodiment, a mobile device may comprise one or more interfaces for detecting location reference nodes in view of the mobile device and a client module to send a location query to a location database. The location query may comprise node data identifying the reference nodes in view of the mobile device. The location database may be configured to respond to the location query with positioning information for providing an estimated position of the mobile device. The positioning information may be based on correlated position data and node data received from one or more client devices having Global Positioning System (GPS) position determination capability and configured to report position data and node data for location reference nodes in view. Other embodiments are described and claimed.
