Patent ID: 8818411

Claim:
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.
