Abstract
Described herein are devices, systems, methods, and processes for improving the accuracy of access point (AP) location in a Wi-Fi network using client device data and AP ranging measurements. APs may be deployed across a specific area. The APs can range to one another and form a matrix of measurements. Techniques such as semidefinite programming or multidimensional scaling (MDS) can be employed to transform these AP-to-AP ranges into a set of coordinates. Client devices in the area may also range to the APs. The client devices may provide their location measurement report (LMR) feedback and geo-position estimation to the network. The client devices-provided data, along with the AP-to-AP matrices, may be returned to a location server. The location server can use the data to refine the accuracy of the AP-to-AP graph and ascertain the most probable geo-position of the APs.
