1. A method of characterizing a WLAN access point, comprising:

  • receiving a plurality of positions at which signals transmitted by a WLAN access point have been detected;

    estimating a signal coverage area of the WLAN access point based on the plurality of positions at which the signals were detected;

    dividing the signal coverage area of the WLAN access point into at least one section; and

    assigning a weight to each section of the WLAN access point based on at least one of the estimated signal coverage area and the plurality of positions at which the signals were detected.
