  • Patent number: 7323991
    Abstract: This invention provides a system and method for identifying, locating, authorizing by proximity and communicating with equipment and personnel in a facility that generally employs a series of limited range transceivers for location determination and a distributed wireless data network for data transfer. The system employs unique RF transceiver tags on personnel and equipment that are each uniquely identified and registered with a facility control application that oversees activities in the facility. The tags are tracked by RF communication based upon their proximity to one or more fixed-base networked access points and relays (which transfer location data by RF back to access points) within four range zones. Location data on all tags is uploaded periodically to a location server that interfaces with the facility control server.
