Abstract
A method and system for accuracy analysis of wireless base station location is provided. In one embodiment, data from a set of mobile devices using a wireless base station is collected. A location of a wireless base station is estimated based on locations of the mobile devices (i.e. points) in the collected set. To provide a more accurate location estimation for the wireless base station, the estimated location is analyzed for accuracy based on the collected data. A confidence score is calculated using a weight function with weights for the collected data based on factors, such as, collection size, platform types of the mobile devices, quality, temporal diversity and/or spatial diversity of points corresponding to the mobile devices, etc. An estimated location of the wireless base station may be adjusted based on the calculated confidence score. An estimated coverage region of the wireless base station may be also estimated and adjusted.
