Ideally, the tracked device (e.g., laptop computer, portable printer, hand-held scanner, etc.) is wired or wirelessly connected to a network. The UWB tag in USB form is inserted into a USB port of the device and may be powered by the USB port. A utility on the device, together with an application running on a server for the environment detects the USB tag on the device and instructs the UWB tag to begin "blinking" or broadcasting its presence. The installed UWB tag detecting infrastructure receives and acknowledges the UWB tag's presence by having the application on the server associating a unique device identifier, such as the MAC number of a lapto...
