March 2021 doc.: IEEE 802.11-21/0391r0 Minimizing Impact as a Design Goal Date: 2021-03-08 Authors: Name Chris Beg Affiliations Cognitive Systems Address 560 Westmount Road N. Waterloo ON, CA 560 Westmount Road N. Waterloo ON, CA Phone email chris.beg@cognitivesystems.com Mohammad Omer Cognitive Systems Submission Slide 1 Chris Beg, Cognitive Systems
March 2021 doc.: IEEE 802.11-21/0391r0 Abstract Begin discussion with TGbf to collect feedback on efficiency as it relates to impact of sensing on 802.11 data network performance Submission Slide 2 Chris Beg, Cognitive Systems
March 2021 doc.: IEEE 802.11-21/0391r0 Current Status Sensing is a technology intended to co-exist with a digital communication infrastructure Load percentages range from 1% to 10% as defined in Sensing Use-Cases document [2] Latest Functional Requirements document [1] does not state any preference on minimizing load introduced by sensing Submission Slide 3 Chris Beg, Cognitive Systems
March 2021 doc.: IEEE 802.11-21/0391r0 WLAN Sensing Constraints Sensing Use-Cases document [2] lists wide range of example applications, which vary in MAC/PHY constraints Sensing ultimately adds utility for the end-user, but communication will remain primary usage Sensing will occupy a percentage of available bandwidth, but can potentially impact data latency, throughput, available burst size. Sensing needs to ensure necessary resources are available for diverse list of use-cases, but also be aware of its impact on communication services and limit this impact to acceptable levels Submission Slide 4 Chris Beg, Cognitive Systems
March 2021 doc.: IEEE 802.11-21/0391r0 WLAN Sensing Design Options Sensing can leverage the many MAC/PHY features that 802.11 provides in order to achieve its goals E.g., Operating frequency, variable bandwidth, multiple antennas flexible topology, broadcasts transmissions, existing transmissions Contributions [3][4] outline a number of different sensing roles and scenarios which will help realize different use-cases It is important for TGbf to enable full use of the flexibility in the 802.11 MAC/PHY to minimize the system impact across the use-cases Submission Slide 5 Chris Beg, Cognitive Systems
March 2021 doc.: IEEE 802.11-21/0391r0 Thoughts Features introduced by TGbf should minimize the network impact, understanding fundamental WLAN use is digital communication Submission Slide 6 Chris Beg, Cognitive Systems
