    Abstract: A real time location system (RTLS) is provided for determining three-dimensional locations of nodes in an environment. The RTLS system includes at least one node associated with an asset in the environment. The at least one node has an unknown location. The system further includes at least one tracking device that communicates with the at least one node to obtain location data associated with the unknown location of the at least one node. A location module receives the location data associated with the unknown location of the at least one node and determines a real-time three-dimensional current location of the at least one node based on the location data. The real-time three-dimensional current location having x, y and z coordinates and the z coordinate indicates a height of the at least one node in the environment.

    Abstract: Systems and methods for tracking, locating, identifying, or mapping movements of persons or personnel within a facility may include badges carried by individuals throughout the facility. These badges can each include a transmitter configured to transmit signals including signature information identifying the badges and also identifying codes of each signal transmitted. In addition, a plurality of dispensers can be positioned at selected locations of the facility and can include receivers that receive the signals transmitted by the transmitters of the badges. These receivers also can be configured to transmit information related to the received signals to one or more processors configured to identify each badge from which signals are received based upon the signature information and also to determine the proximity, range, distance, or zone between the badge identified and the receivers.
