Wireless Position Location And Tracking System
First Claim
1. A method for real-time position location of an object within an indoor facility, the method comprising:
- wirelessly transmitting data of a first plurality of measurements from a tag of an object of a plurality of objects to at least one of a plurality of network monitors;
wirelessly transmitting data of the first plurality of measurements from at least one of the plurality of network monitors to at least one of a plurality of access points;
transmitting data of the first plurality of measurements from the at least one of the plurality of access points to a location positioning engine;
generating and continuously updating a real-time mapped space of a radiofrequency environment of the indoor facility based on the data of the first plurality of measurement; and
generating a real-time position location in an X-Y-Z coordinate for at least one of the plurality of objects in accordance with the received data of the first plurality of measurements and the real-time mapped space of the radiofrequency environment of the indoor facility.

Abstract
Techniques for accurate position location and tracking suitable for a wide range of facilities in variable environments are disclosed. In one aspect, a system for position location comprises a plurality of sensors (e.g. a network monitor, an environment sensor) for generating measurements of a plurality of sources, a plurality of objects or tags, each object generating measurements of the plurality of sources, and a processor for receiving the measurements and generating a position location for one or more objects in accordance with the received measurements. In another aspect, a position engine comprises a mapped space of a physical environment, and a processor for updating the mapped space in response to received measurements. The position engine may receive second measurements from an object within the physical environment, and generate a position location estimate for the object from the received second measurements and the mapped space.
