Abstract
A method to support client device position discovery within a building includes ascribing building position coordinates to beacons within the building. The building position coordinates are converted to physical position coordinates. The physical position coordinates are augmented with at least one additional parameter that supports position resolution. A client device communicates with accessed beacons positioned within the building. A beacon location database characterizing the physical locations of the accessed beacons is also accessed. The physical location of the client device is computed based upon the physical locations of the accessed beacons.
