ULTRA-WIDEBAND RANGING AND LOCATION TRACKING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240302484 titled 'ULTRA-WIDEBAND RANGING AND LOCATION TRACKING

Simplified Explanation

The patent application discusses an ultra-wideband (UWB) antenna array system that improves accuracy for phase-difference-of-arrival (PDOA) in ranging and location tracking. By using multiple antennas, the system can determine the location of a client based on the phase differences between signals received.

The system receives a poll signal from a client through two antennas to determine the initial PDOA.
It then transmits a response signal to the client and receives a final signal through three antennas to calculate additional PDOA measurements.
By combining these measurements, the system can accurately determine the client's location.

Key Features and Innovation

Utilizes an UWB antenna array system to improve accuracy in PDOA measurements.
Enables precise location tracking of clients by analyzing phase differences between signals received by multiple antennas.
Enhances ranging and location tracking capabilities for various applications.

Original Abstract Submitted

ultra-wideband (uwb) ranging and location tracking, and particularly an uwb antenna array system and methods for improving the accuracy for phase-difference-of-arrival (pdoa) is provided. uwb ranging may include receiving a poll signal from a client via a first and second antenna. pdoa between the first and second antenna is determined based on the poll signal. a response signal is transmitted to the client, and a first portion of a final signal is received via the first antenna and a third antenna and a second portion of the final signal is received via the second and third antenna. pdoa between the first and third antenna is determined based on the first portion, and pdoa between the second and third antenna is determined based on the second portion. the client location is then determined based on the pdoas.
