6G/5G Research
–
802.11 already have a new PAR for MAC & PHY changes to
use WiFi for sensing
–
New wireless air interfaces are expected to support massive number
of M2M links at very low power.
•
UWB and 4z actually already support some of that.

Future Directions for UWB (2)
Slide 4
•
Spin out 4z/UWB and related building blocks from
802.15.4 into self-sufficient specification to enable strong
UWB centric ecosystem
•
Example Phy & MAC improvements & feature
enhancements relative to 4z baseline
–
Enhance operating range, efficiency (complexity/power), accuracy, and
integrity via suitable new waveforms and signaling techniques
–
Improved capabilities for native discovery / connection setup
–
Further optimized protocol framework targeting specific use cases
–
Improved support for data-less ranging
–
Consider proliferation of new channels / frequency bands
–
Enhancements for “Depth Sensing & Mapping”
–
Limit use of payload bearing formats to control signaling and non-streaming
data applications to prevent “self-cannibalization” of UWB’s strong nascent
success
•
Regulatory & Coexistence Considerations
Discussing the evolution of Ultra-Wideband (UWB) technology within IEEE 802 standards, focusing on proposed future directions, improvements, and potential use cases. The presentation covers observations, trends, and spin-out strategies to enhance UWB capabilities, including advancements in PHY and MAC protocols, expansion of operating range, efficiency, and support for various applications.

doc.: <15-20-0325-00-wng0> November 2020 Future Directions for UWB (1) Observations: An emerging trend in design new wireless air interfaces is to consider Communication, Sensing, Ranging, and Control in the design of new PHY & MAC protocols to accommodate different uses cases and scenarios. 6G/5G Research 802.11 already have a new PAR for MAC & PHY changes to use WiFi for sensing New wireless air interfaces are expected to support massive number of M2M links at very low power. UWB and 4z actually already support some of that. With some further improvement and development, UWB is in a good position to address many of the CSRC use cases targeted by other air interfaces in a way that strongly integrates with and builds on current 4z deployments Submission Slide 3 Apple Inc
