Patent ID: 7626545

Claim:
A system for real-time position location of an object within an indoor, multi-floor facility, the system comprising: a plurality of beacon emitters positioned within the indoor multi-floor facility, each beacon emitter generating a radiofrequency signal; a plurality of network monitors, each network monitor attached to a wall outlet of the indoor, multi-floor facility and generating a first plurality of measurements, the first plurality of measurements comprising data, the data comprising signal strength from each of the plurality of beacon emitters received by the network monitor; a plurality of mobile objects located within the indoor, multi-floor facility, each mobile object having a respective tag associated therewith, each tag generating a second plurality of measurements, the second plurality of measurements comprising data, the data comprising signal strength from each of the plurality of beacon emitters received by the tag; a plurality of access points located within the indoor, multi-floor facility, at least one of the plurality of access points wirelessly receiving data of the first plurality of measurements from each of the plurality of network monitors utilizing a 802.11 communication link, wherein at least one of the plurality of network monitors wirelessly receives data of the second plurality of measurements from the tag of each mobile object using a 802.15.4 communication link and wirelessly transmits the data of the second plurality of measurements to at least one of the plurality of access points utilizing the 802.11 communication link; and a location positioning engine for receiving through the plurality of access points (1) data of at least one of the first plurality of measurements from each of the plurality of network monitors and (2) data of at least one of the second plurality of measurements from the tag of at least one of the mobile objects of the plurality of mobile objects, the location positioning engine generating a real-time position of each of the plurality of mobile objects within the indoor, multi-floor facility.
