1. A computer-implemented method comprising: receiving a location query associated with a wireless communication device; dividing, by one or more processors, an area into multiple zones, individual zones of the multiple zones being located at least partially within the area, and individual zones of the multiple zones being associated with respective zonal signal propagation models; determining, by the one or more processors, an estimated location of the wireless communication device within the area, the estimated located being based at least in part on a global signal propagation model associated with the area; selecting, by the one or more processors, a target zone among the multiple zones that is closest to the estimated location of the wireless communication device; and determining, by the one or more processors, a final estimated location of the wireless communication device based at least in part on a zonal signal propagation model associated with the target zone, the zonal signal propagation model being one of the respective zonal signal propagation models.
