1. A method performed by one or more computers, comprising:

  • receiving a plurality of sets of location coordinates from one or more mobile devices, each set of location coordinates being associated with a wireless access device;

    determining an effective location of the wireless access device based on a statistical analysis of the received sets of location coordinates, wherein determining the effective location comprises;

    mapping the sets of location coordinates to a plurality of bins, each bin including a unit area in a geographic grid;

    selecting one or more bins from the plurality of bins based on a concentration of received location coordinates in each of the bins using;

    a probability density function; and

    a specified outlier threshold for identifying and excluding one or more outliers in the sets of location coordinates; and

    determining the effective location using sets of location coordinates in the selected one or more bins; and

    providing the effective location to a mobile device for determining an estimated location of the mobile device when the mobile device is located within a communication range of the wireless access device.
