Methods and Apparatuses for Efficient Learning of Unknown Access Point Location Using Trilateration Based on Multi-Resolution

摘要

Methods and systems are presented for estimating a location of an access point (AP) associated with an indoor environment. In some embodiments a method includes obtaining a coarse set of signal information associated with the indoor environment. The method may also include obtaining ranging measurements based on signals received from the AP, computing at least one coarse location estimate of the AP based on the received coarse set of signal information and the ranging measurements, receiving a fine set of signal information associated with the at least one coarse location estimate of the AP, and computing at least one fine location estimate of the AP based on the received fine set of signal information and the ranging measurements, wherein the at least one fine location estimate of the AP is more accurate than the at least one coarse location estimate of the AP.
