Title: DETERMINING COORDINATES OF ACCESS POINTS IN AN INDOOR POSITION LOCATION SYSTEM
Abstract:
Methods, systems, and devices are described for determining and updating coordinates of access points (APs) within a location tracking system. Tools and techniques are described that may provide for automatically determining a coordinate set, which represents coordinates of at least three neighboring APs within a location tracking area. These techniques may be utilized at the time of the APs' deployment and/or when APs are moved or relocated to a new location. The methods, systems, and devices may be applicable to single- and multi-floor location tracking systems. Coordinate and/or coordinate sets of APs may be stored in a location tracking server, and they may used in determining a location of tracking tags with the location tracking area. The stored coordinates and/or coordinate sets may be updated as the location of APs change.
