Feb 2023 doc.: IEEE 802.11-23/0260r0 AMP TIG Progress Report AMP TIG Progress Report Author: Name Bo Sun Affiliation Address Sanechips Phone Email Sun.bo1@sanechips.com.cn Submission Slide 1 Bo Sun (Sanechips)
Feb 2023 doc.: IEEE 802.11-23/0260r0 Brief Catch-up of AMP TIG s Formation Background - 11-22/0645r2 was presented and discussed in May 2022 interim WNG SC meeting with two SPs run: Straw Poll #1: Do you think ambient power-enabled IoT for WLAN would be an interesting topic for 802.11 to study as a separate activity? (Result: 79Y/23N/28A) Straw Poll #2: Do you support the formation of a new 802.11 Topic Interest Group (TIG) for Support of Ambient Power-Enabled IoT for WLAN ? (Result: 70Y/21N/36A) The formation of AMP TIG was approved at the 2022 May session, see slide 11 (Motion #6) in 11-22- 0597-03-0000-may-2022-working-group-motions.pptx The AMP TIG had its first meeting during Jul 2022 Plenary week. Bo Sun was appoint as the chair of AMP TIG Scope: - describe use cases for 802.11 ambient power-enabled IoT devices and - investigate the technical feasibility of features to enable 802.11 WLAN support of ambient power enabled IoT devices. Output: complete a report on this topic at or before the March 2023 session Timeline: contribution collection (Jul Nov, 2022) , report draft development (Jul 2022 Mar 2023) - - - Submission Slide 2 Bo Sun (Sanechips)
Feb 2023 doc.: IEEE 802.11-23/0260r0 AMP TIG s Progress Totally 10 meetings and 5 TCs were held during or between IEEE 802.11 plenary and interim sessions Around 30 technical contributions were submitted, presented and discussed, covering use cases, technical feasibility, regulation, impact to standard, etc. A tech report draft (11-22/1562) was proposed during Sep 2022 plenary session and continuously improved based on following discussion The latest revision of the tech report draft is 11-22/1562r8 A summary introduction 11-23/0375r0 was developed for a brief introduction to the tech report and a contribution (11-23/0388r2) with same content as 11-23/0375r0 was presented in WNG The technical report content was incorporated into 11-23/0436r0 together with the TIG SP and motion results, with TIG participants unanimous approval. AMP TIG approved the final version of technical report as in 11-23/0436r0 AMP TIG approved to request WG to form a Study Group to develop PAR/CSD Submission Slide 3 Bo Sun (Sanechips)
Feb 2023 doc.: IEEE 802.11-23/0260r0 AMP TIG Motion #1 Approve to incorporate the content of 11-22/1562r8, together with the result of consensus SP in 11-23/0406r1 and result of motions on slide 23 and 24 in 11-23/0172r4 into the final version of the AMP technical report (11- 23/0436r0) and grant the AMP TIP chair edit privilege. Moved: Weijie Xu Seconded: Joerg Robert Result: approved unanimously Submission Slide 4 Bo Sun (Sanechips)
Feb 2023 doc.: IEEE 802.11-23/0260r0 AMP TIG Motion #2 Request 802.11 Working Group approval to form an 802.11 AMbient Power Study Group (AMP SG) with the intent of creating a PAR and CSD. The Study Group will investigate MAC and PHY capabilities to enable 802.11 WLAN support of ultra-low complexity and ultra-low power consumption (e.g. less than one milliwatt) devices powered by ambient power source, and reuse existing 802.11 features as much as possible, with a target start of the task group in Jan 2024. Moved: Joerg Robert Seconded: James Yee Result: 39Y/0N/3A Note: reference documents include 11-23/0260r0 and the numerous AMP TIG contributions on this topic. Submission Slide 5 Bo Sun (Sanechips)

Feb 2023 doc.: IEEE 802.11-23/0260r0 AMP in WLAN Study Motivation (11-23/0375r0) The Wi-Fi IoT network is competitive from deployment cost perspective, thanks to widespread deployment and use of unlicensed frequency band. However, there remain lot of use cases and applications that can not be addressed using existing Wi-Fi IoT technologies: a device driven by a conventional battery is not applicable, e.g., under extreme environmental conditions (e.g., high pressure, extremely high/low temperature, humid environment) or maintenance-free devices are required (e.g., no need to replace a conventional battery for the device) ultra-low complexity, very small device size/form factor (e.g., thickness of mm), and longer life cycle etc. are required Submission Slide 7 Bo Sun (Sanechips)
Feb 2023 doc.: IEEE 802.11-23/0260r0 AMP in WLAN Study Motivation (11-23/0375r0) From technical perspective, there are many advantages to support AMP IoT in 802.11 Many emerging implementations in 802.11 network have demonstrated both feasibility and technical/business potentials With potential enhancement, the legacy infrastructure can be reused Easy for AMP function design by building upon the existing 802.11 features, such as 802.11ba, 802.11ah and legacy 802.11 power management mechanism. Minimize design efforts by reusing the existing mechanism, e.g. 802.11ba WUR and OOK, simplified 802.11ah MAC, access control mechanism. power management mechanism, etc. From business perspective, AMP devices and Wi-Fi eco-system are mutually beneficial Create new IoT service opportunities in many to-Business and to-Customer areas by enriching WLAN IoT applications Explore the high WLAN market share and further expand Wi-Fi ecosystem market portfolio Achieve much lower CapEx and OpEx for the verticals with free unlicenced frequency band and existing deployment Good matching to the local area deployment requirement Submission Slide 8 Bo Sun (Sanechips)
