Method and system for creating a radio frequency signature for a signature region in a coverage area of a wireless communication system

摘要

In a wireless communication system, radio frequency signal propagation characteristics associated with a signal transmitted from several locations in the coverage area of the wireless communication system are measured. Next, a plurality of signature regions are defined in the coverage area, wherein the signature regions each contain several selected locations having selected measured radio frequency signal propagation characteristics. For a selected signature region, the associated measured radio frequency signal propagation characteristics are processed to produce a spatially averaged radio frequency signature for the selected signature region. The spatially averaged radio frequency signature represents the dominant features of the radio frequency signal propagation characteristics of a signal transmitted within the selected signature region. Finally, an association between the spatially averaged radio frequency signature and the selected signature region is recorded.
