IEEE 802.15-43-0161-00-0mag PAR and CSD Review: March 2024 Session

Report on the review of PARs and CSDs submitted by Phil Beecher from Wi-SUN Alliance for the IEEE 802.15 Working Group's March 2024 plenary session. The document highlights comments and suggestions for various IEEE standards, particularly focusing on the amendments related to Wireless Personal Area Networks (WPANs) and wireless communication technologies. Key points include clarifications on project scopes, coexistence with other standards, and considerations for power transfer and energy harvesting technologies.

  2. March 2024 doc #: IEEE 802.15-43-0161-00-0mag PAR and CSD Review by 802.15 SCM • 802.1 PARs and CSDs • 802.1ASeb - Amendment: Optional Use of Announce , PAR and CSD • No comments • 802.3 PARs and CSDs • 802.3dm - Amendment: Asymmetrical Electrical Automotive Ethernet, PAR and CSD • No comments Submission Slide 2 Phil Beecher (Wi-SUN Alliance)

  3. March 2024 doc #: IEEE 802.15-43-0161-00-0mag PAR and CSD Review by 802.15 SCM • 802.11 PARs and CSDs • 802.11bf - Amendment: Enhancements for Wireless Local Area Network (WLAN) Sensing, PAR modification • No comments Submission Slide 3 Phil Beecher (Wi-SUN Alliance)

  4. March 2024 doc #: IEEE 802.15-43-0161-00-0mag PAR and CSD Review by 802.15 SCM • 802.11 PARs and CSDs (cont) • 802.11bp -Amendment: Enhancements for Ambient Power Communication (AMP), PAR and CSD • PAR Comments • 2.1 Title • There is not a definition of Ambient Power Communication –it appears that this project might include power transfer, so the title is misleading • 5.2b Scope of Project • The scope talks about “energy harvesting”, then in 8.1 “power transfer” is mentioned. If power transfer is part of the project, then it should be included in the scope. • The scope mentions coexistence with 802.11-2020: will it be interoperable with 802.11-2020? Submission Slgide 4 Phil Beecher (Wi-SUN Alliance)

  5. March 2024 doc #: IEEE 802.15-43-0161-00-0mag PAR and CSD Review by 802.15 SCM • 802.11 PARs and CSDs (cont) • 802.11bp PAR Comments • 5.2b Scope of Project (cont) • How will the project ensure coexistence with other 802 standards operating in the bands, e.g. 802.15.4 and 802.15.6. This is particularly concerning as we understand that power transfer using a downlink is under consideration (doc 11- 24-0163), despite not being included in the scope of the project. How will coexistence with the 100s of millions of 802.15.4 devices using sub 1GHz, as well as sub 1 GHz (802.11ah) be managed? • We suggest adding: This amendment shall defines mechanisms for coexistence for an AMP device and deployed devices compliant with IEEE Std 802.15.4TMthat operate in the same radio frequency band as the AMP device. • Currently there is no indication of range / distance for power transfer – please specify. • Also note regulatory constraints including safety (i.e. human body).

  6. March 2024 doc #: IEEE 802.15-43-0161-00-0mag PAR and CSD Review by 802.15 SCM • 802.11 PARs and CSDs (cont) • 802.11bp PAR Comments (cont) • 8.1 – First mention of power transfer, should include this in the scope. • 802.11bp CSD Comments • CSD describes applications where there is adequate ambient power without wireless power transfer – what are the applications that require this? • 1.2.3 evern lower - typo • 1.2.4b Proven technology – this section comments that 802.11 is a proven radio technology, but it does not describe how the power transfer or energy harvesting is proven – please include some examples. • Known cost factors: please provide evidence or a reference of how AMP devices are “accepted by the market as having balanced costs” ?
