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.
