Abstract
A method and apparatus determines a physical location of a wireless infrastructure device. At least one coarse location data from an associated terminal device is determined. Additional coarse location data are stored and accumulated. The device location is considered accurate by determining that enough received coarse location data has been received.

9. A method for determining a physical location of a wireless infrastructure device, comprising:
-
receiving at least one coarse location data from an associated terminal device; receiving beacons from the at least one associated terminal device that provide signals of opportunity from which additional location data can be derived; storing and accumulating received coarse location data and the additional location data; and determining that enough received coarse location data is received to consider the location of the infrastructure device to be accurate. - View Dependent Claims (10, 11, 12, 13)

14. An infrastructure device, comprising:
a location processor comprising; a location calculation engine configured to determine location coordinates of the infrastructure device from received location data, and to provide, or indicate an inability to provide, location coordinates; a location parameter database for storing data related to determining a location of the infrastructure device; a messaging interface configured to communicate with at least one associated terminal device to receive at least one coarse location data from an associated terminal device that may be used by the location calculation engine to determine a location; and a radio interface configured to receive beacons from the at least one associated terminal device that provide signals of opportunity from which additional location data can be derived by the location calculation engine for determining the location coordinates; wherein the location calculation engine is further configured to determine that enough received coarse location data is received to consider the location of the infrastructure device to be accurate. - View Dependent Claims (15, 16, 17, 18)
