Abstract:
A wireless location system is disclosed including one or more location centers for outputting locations of mobile stations (MS) for both local and global MS location requests via Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: two-way TOA and TDOA; pattern recognition; distributed antenna provisioning; GPS signals. Difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with: (a) adapting and calibrating system performance according to environmental and geographical changes; (b) capturing location signal data for continual enhancement of an historical database; (c) evaluating MS locations via heuristics and constraints related to terrain, MS velocity and MS path extrapolation, and (d) adjusting likely MS locations. The system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.
