    Abstract: Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

    Abstract: Location-independent approaches are provided for determining, using a mobile device, whether a wireless transmitter has been moved to a new location. An example method includes obtaining at least a portion of a reference radio frequency (RF) signature database; measuring signals from a plurality of wireless transmitters proximate to the mobile device; identifying a candidate wireless transmitter; deriving an observed radio frequency (RF) signature for the candidate wireless transmitter from signals from at least one wireless transmitter of the plurality of wireless transmitters other than the candidate wireless transmitter; determining whether the candidate wireless transmitter has been moved to a new location by comparing the observed RF signature for the candidate wireless transmitter to a reference RF signature associated with the candidate wireless transmitter; and generating an indicator that the candidate wireless transmitter has been moved responsive to the candidate wireless transmitter having been moved.
