  • Aggregating location accuracy data to estimate accuracy of a wireless locating system
    Patent number: 7634266
    Abstract: Location determination accuracy in a mobile telecommunications environment can be estimated based on location determination accuracy data for multiple empirical test calls in a geographic region. A location of a wireless station for each test call is determined using one of multiple wireless locating techniques, and an approximate ratio of wireless locating techniques for the empirical test calls is identified. Subscriber call data relating to location estimates determined using one of the wireless locating techniques is received. Location determination accuracy in the geographic region is estimated by combining the subscriber call data according to the identified ratio. To facilitate determinations of locating accuracy, the geographic region is logically segmented into multiple areas. Each area is associated with a performance profile that relates to a locating accuracy performance.
