Abstract
In an embodiment a real-time location method includes sending, by a master beacon device and one or more beacon repeater devices, ultra-wideband beacon frames, wherein the ultra-wideband beacon frames are transmitted as interleaved pairs of ultra-wideband beacon frames, wherein each interleaved pair is sent either from the master beacon device or the one or more beacon repeater devices, wherein each interleaved pair includes a first ultra-wideband beacon frame and a second ultra-wideband beacon frame, and wherein, for each interleaved pair, the first ultra-wideband beacon frame and the second ultra-wideband beacon frame are transmitted with a master time delay, receiving, by one or more tag devices, at least one of the interleaved pairs of ultra-wideband beacon frames, receiving, by the one or more beacon repeater devices, at least one of the interleaved pairs of ultra-wideband beacon frames, receiving, by one of a plurality of tag response receptor units, at least one of the interleaved pairs of ultra-wideband beacon frames, sending, by the one or more tag devices, ultra-wideband tag response frames and receiving, by the one of the plurality of tag response receptor units, at leas…
