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.

A method performed by a transmitting station includes selecting a type of a management frame, generating the management frame according to the selected type of the management frame, the management frame including a dialog token, transmitting the management frame to a first receiving station, and receiving a response frame from a second receiving station as a response to the management frame. When a first type of the management frame is selected, a value of the dialog token is selected to uniquely identify the management frame on single receiving station. When a second type of the management frame is selected, a value of the dialog token is selected to uniquely identify the management frame on a plurality of receiving stations.

A method for positioning an internet of things (IoT) device with AR glasses is provided. The method includes: acquiring an indoor map; determining an AR-position of the AR glasses on the indoor map and a viewing direction of the AR glasses based on initial information of the AR glasses; receiving from the AR glasses tracking information concerning the IoT device to be positioned; and determining an IoT-position of the loT device to be positioned from the AR-position and the viewing direction in combination with the tracking information of the AR glasses.

A multi-communication-interface system methods implement fine locationing while conserving battery power. A first wireless-communication interface of a first multi-communication-interface tape node located at a first location in an area detect a first wireless signal from a second tape node at a first time. A first receiver of a second wireless-communication interface of the first multi-communication-interface tape node is activated in response to detecting the first wireless signal and used to receive a first response signal from a first wireless tag in response to an interrogation signal. The first receiver is deactivated to conserve power within an internal battery of the at least one second multi-communication-interface tape node and a location of the first wireless tag at the first time is determined as the first location.
