Abstract
Systems and methods for locating wireless devices in a wireless network. A diagnostic client on a wireless device generates timing data based on clock data received from sectors of towers communicating with the device. The timing data can be used to generate probability bands that approximate the location of the device in the wireless network. The broadcast regions of the sectors and/or the probability bands can also be used to generate the probable location of a wireless device in a wireless network. The diagnostic data can then be binned in a grid based on the approximate location of the wireless device. The statistical contributions of multiple devices to the grid can be used to characterize the performance of the wireless network.
