A system and method for real-time location detection consists of a scalable real time location system (RTLS). It provides revised real time object location determinations. It includes a tag within a location environment, a processor to calculate a location of the tag, and at least one exclusion zone in the environment. Processing includes an original location determination of the tag and a revised location determination of the tag. The revised location determination is calculated by applying attributes of at least one exclusion zone to the original location determination of the tag. Some exclusion zones are defined by no-fly exclusion zones. The revised location determination improves the operation of the RTLS by correcting for impossible and improbable original location determinations. For embodiments, system deployment consists of three phases: collection of training and testing data, network training and testing, and network adaptive maintenance.

Real-time location detection using exclusion zones

Objects are located within at least one mapped field region. Environments for location tracking are mapped through a configuration setup flexibly supporting multiple objects with precision and speed. Host and Repeater devices are located at vertices of polyhedra defining spaces. Polyhedra edge lengths are defined as the modified physical distance between two devices. This morphing employs parameters measured by or input to the system. Morphed three dimensional subzones are defined within the volume of the polyhedra defined by the devices at the vertices.

Position locating by polyhedral morphing

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. Tag data is monitored by the facility control server to track, authorize and deauthorize certain data transfers, movements and activities in accordance with rules established for each tag (or type of tag) within the facility control server's application. Wireless networking (WiFi, for example), in combination with the RF-derived location information, allows the facility control server to correlate and transmit data to staff in conjunction with location and proximity. WiFi can transmit authorizations, deauthorizations and general data based upon triggers established by proximity and location. Likewise, data can be transmitted over WiFi from readers etc. from personnel and equipment located and identified by the system.
