Abstract
In an embodiment a real-time location method includes sending and receiving ultra-wideband frames using an exchange protocol based on an ultra-wideband frame format, wherein the exchange protocol defines a location rate frame format including a beacon section having a series of time slots associated to at least one frame of interleaved pairs of beacon frames, wherein a first beacon frame and a second beacon frame of each pair are separated in time by a master time delay, and wherein, between time slots assigned to the beacon frames of an opening pair having an initial one of the beacon frames within the beacon section, an array of time slots is respectively assigned to the first beacon frames of the remaining pairs, and a tag response section including a sequence of time slots associated to tag response frames.
