1. A computer-implemented method for self-labeling an access point, the method comprising:

  • receiving signals including geographic codes at the access point from a first device and one or more second devices;

    filtering the signals received from the first device and the one or more second devices by discarding a certain number of signals received from the first device until a remaining number of the signals from the first device is comparable to that received from the one or more second devices in a predefined amount of time;

    extracting, with a processor, the geographic codes from the filtered signals;

    decoding the geographic codes to determine the locations of the first and the one or more second devices;

    determining a plurality of estimations for an access point location over time based on the locations of the first and the one or more second devices; and

    determining the access point location based at least in part on a geometric center of the plurality of estimations.
