Ultra wide band based zone determination system

A system including:

• one or more ultra-wideband (UWB) transceivers configured to communicate an UWB signal that encodes radio packets that includes at least a preamble and a start frame delimiter (SFD) enabling a receiver to recover a reception timestamp and a channel impulse response (CIR) of the transmission, including:
• a first station containing a UWB transmitter configured to generate the UWB signal and split the UWB signal to a first split signal and a second split signal via a splitter, wherein the UWB transmitter includes at least a first antenna and a second antenna with defined spatial separation connected via connecting element configured to propagate the signal with a defined time delay, wherein the UWB transmitter is further configured to communicate one or more radio packets through the first split signal and the second split signal, wherein the UWB transmitter determines a first delay between the first split signal transmitted at the first antenna and a second delay between the second signal transmitted at the second antenna, wherein the second delay introduced by the connecting element is larger than the first delay;
• and
• a second station and a processor in the second station is further programmed to decode the radio packets to extract CIR information, wherein the CIR information is utilized to identify both an arrival time of the radio packet and a relative time delay.

A ultra-wideband (UWB transceiver) system including:

• a transceiver configured to send a signal that includes encodes radio packets that include at least a preamble and a start frame delimiter (SFD);
• and
• a first station containing a UWB transmitter configured to generate the UWB signal and split the UWB signal to a first split signal and a second split signal, wherein the UWB transmitter includes at least a first antenna and a second antenna and the UWB transmitter is configured to communicate one or more radio packets through the first split signal and the second split signal, wherein the UWB transmitter determines a first delay between the first split signal transmitted at the first antenna and a second delay between the second signal transmitted at the second antenna, wherein the second delay introduced by a connecting element is larger than the first delay;
• and
• a UWB receiver configured to extract channel impulse response (CIR) information from the one or more radio packets received from a responder, and output a relative distance to the responder utilizing the CIR information, both the first delay and the second delay, and the time stamp.
