March 2024 doc.: IEEE 802.11-24/0571r0 Future Light Communications Requirements Date: 2024-03-15 Authors: Name Nikola Serafimovski Affiliations pureLiFi Address Phone email nikola.serafimovski@purelifi.com volker.jungnickel@hhi.fraunhofer.de Volker Jungnickel Fraunhofer HHI Submission Slide 1 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Abstract This presentation proposes the technical requirements for the development/enhancement of Light Communications to be market relevant for 2028 as a next step after 802.11bb. Submission Slide 2 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Current status 802.11bb has been well received with significant interest in the standard from the market 802.11bb is limited to 11n, 11ac and 11ax capabilities Future evolution of Light Communications is required to ensure market relevance Submission Slide 3 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Market requirements for future LC Customer discussions have provided feedback on key improvements required in the 2027+ timeline to include: Support of the latest Wi-Fi standard Higher speed Additional wavelengths for operations Better MIMO Each of these requirements can be defined as specific technical consequences Submission Slide 4 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Technical requirements for LC Evolution to use the latest Wi-Fi standard Next LC update should include support for 11be (ideally 11bn if possible?) Higher speed Greater electrical bandwidth for the opto-electrical front end (e.g., Light Antenna) Light Antennas can easily accommodate 320 MHz continuous bandwidth or higher Additional wavelengths for operations Current definition of 800-1000 nm is sufficient for a start New wavelengths should be included to allow greater optical power output (better range, data rates, etc.) Better MIMO Practical implementations of 11bb struggle to use more than 2 wavelengths in the 800- 1000 nm range Submission Slide 5 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Proposed scope of work for LC Add integration with the 11be/bn PHYs Same goal as IMMW No changes in the MAC (same as 11bb) No impact on anything else for IMMW Add support for use of 1200 1550 nm spectrum The spectrum to be used is additive to the current spectrum requirement Update the LC MIMO (wavelength division multiplexing) clause for 11bb Better definition of the WDM spectrum utilization Confine the effective field-of-view to ensure interoperability Submission Slide 6 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Proposed path forward Integrate LC as part of the IMMW TG LC will introduce no additional requirements to the group beyond: Expand the scope of the PAR to include the light spectrum Augment the 11bb MIMO clause to include additional parts of the light spectrum and define the spectrums of relevance Submission Slide 7 Nikola Serafimovski, pureLiFi
March 2024 doc.: IEEE 802.11-24/0571r0 Straw poll Would you support including LC in the IMMW PAR? Yes No Abstain Submission Slide 8 Nikola Serafimovski, pureLiFi
