ANNOUNCING UWB / NBA-UWB-MMS RANGING ROUNDS VIA NARROWBAND-BASED ADVERTISEMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18381029 titled 'ANNOUNCING UWB / NBA-UWB-MMS RANGING ROUNDS VIA NARROWBAND-BASED ADVERTISEMENTS

Simplified Explanation

The patent application describes techniques for using a combination of ultra-wideband (UWB) and narrowband (NB) signaling to improve the operating range and efficiency of devices.

  • The first subsystem of a device determines parameter data for a ranging round, which can involve UWB and/or NB-assisted UWB multi-millisecond ranging.
  • The parameter data is transmitted to a second subsystem of the same device.
  • The parameter data includes a first time associated with a first time domain for performing ranging.
  • The second subsystem determines a second time based on the first time, which is associated with a second time domain for performing NB signaling (e.g., using Bluetooth Low Energy protocol).
  • The device transmits an advertisement packet via an NB signal that indicates the second time.
  • The device then initiates the ranging round at the first time.

Potential applications of this technology:

  • Improved range and efficiency in wireless communication devices.
  • Enhanced localization and tracking capabilities in indoor environments.
  • More reliable and accurate positioning systems for various industries, such as logistics, healthcare, and manufacturing.

Problems solved by this technology:

  • Limited operating range and efficiency of wireless communication devices.
  • Challenges in accurately determining the position and location of devices in indoor environments.
  • Interference and signal degradation issues in crowded wireless environments.

Benefits of this technology:

  • Extended operating range for wireless communication devices.
  • Improved accuracy and reliability in determining device position and location.
  • Enhanced efficiency and performance in wireless communication systems.
  • Compatibility with existing NB signaling protocols, such as Bluetooth Low Energy.


Original Abstract Submitted

Techniques are provided for utilizing a hybrid of ultra-wideband (UWB) and narrowband (NB) signaling to provide more efficient operating range and operating efficiency. In one example, a first subsystem of a first device may determine parameter data for a ranging round (e.g., UWB and/or NB-assisted (NBA) UWB multi-millisecond (MMS) ranging), and transmit the parameter data to a second subsystem of the first device. The parameter data may indicate a first time associated with a first time domain for performing ranging. The second subsystem may determine a second time based on the first time, whereby the second time is associated with a second time domain for performing NB signaling (e.g., via a Bluetooth Low Energy (BLE) protocol). The first device may transmit via an NB signal an advertisement packet that indicates the second time. The first device may then initiate the ranging round at the first time.
