摘要：Apparatus and method for dynamically updating a channel model used forwireless local area network based positioning. In one embodiment, a wireless deviceincludes a positioning system. The positioning system is configured to determine a

position of the device based on signals received from wireless local area network accesspoints. The positioning system is also configured to determine a likelihood that thewireless device is positioned at each of a plurality of points of a positioning grid based ona received signal strength value for each of a plurality of access points. The positioningsystem is further configured to update a reference power estimate for each access pointbased on the likelihoods. The positioning system is also configured to update the pathloss exponent of the channel model.
