Abstract: A real-time location system for tracking assets at a site includes at least one tracking tag, a plurality of locating device nodes and a plurality of gateways. The plurality of locating device nodes are each configured to connect wirelessly with and transmit a locating signal to a first one of the plurality of gateways, receive an acknowledgement signal from the gateway acknowledging receipt at an acknowledged received signal strength and determine whether the acknowledged received signal strength meets pre-established conditions. The plurality of locating device nodes are further configured to set a listen before talk threshold according to historical noise floor readings. Each of the plurality of gateways is configured to receive one or more locating signals and to determine connection between the gateway and the server has failed and disconnect the wirelessly connected locating device node from the gateway.

Abstract: The disclosure describes a real-time location system for tracking assets at a site. The system includes one or more tracking tags for carrying by or on the assets, one or more locating device nodes and a processing application. Each tracking tag includes a short-range radio frequency signal transmitter configured to transmit a beacon signal with unique identification information of the tracking tag. Each locating device node includes a signal receiver configured to receive the beacon signals at a received signal strength and a long-range radio frequency transmitter configured to transmit, using a spread spectrum, long-range modulation over a wide area network, locating signals including the unique identification information of the tracking tag and a received signal strength indicator representing the received signal strength. The processing application is configured to associate tracking tags and locating device nodes based upon the received signal strength indicator.

Abstract: A tracking tag system includes a tag case, a first tag case back plate and a second tag case back plate. The tag case has a mating surface and is configured to house a PCB having a transmitter and circuitry for controlling the transmitter. The first tag case back plate is configured to mate with the tag case to enclose and totally protect the PCB, the transmitter, the circuitry and a battery of a first type against ingress of water during immersion and against dust ingress. The second tag case back plate configured to enclose and totally protect the PCB, the transmitter, the circuitry and a battery of a second type against ingress of water during immersion and against dust ingress.
