March 2023 doc.: IEEE 802.11-23-0283r0 Abstract This presentation highlights the need, use-cases and technology of Light Communications in IEEE 802.11bb and IEEE 802.15.13. Submission Slide 2 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 The Taxonomy of Light Communications Not all light communications is LiFi. It s is important to understand the differences between these types of communications, as they all have different applications. Free Space Optics Light Fidelity Optical Camera Communications OCC FSO LiFi Low Speed Geo Location Advertisements Notifications Backhaul Long-distance communications Secure high-speed mobile wireless communications Submission Slide 3 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 Various use-cases drive requirements where RF solutions have limitation Defence & Environment & Industrial Commercial Data Office & Retail & Financial Smart City & Transport Consumer & Lifestyle Field command Secure comms Harsh enviro Underwater Data centres Industry 4.0 IoT sensors Safe enviro Smart building Secure comms Dense network Net offload Indoor location Shop analytics Payments Back office Smart city Smart transport Streetlights Backhaul Mobile devices Smart home Entertainment Lighting Submission 4 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 Light Communication Key facts Mobile communication by using light Bidirectional, high-speed Useful complement to RF Unique Selling Points Higher capacity/area in small hotspots 1 10 Mbps/m (RF) 100+ Mbps/m (LC) Higher QoS: guaranteed delivery at low latency Robust against jamming, enhanced privacy Complement RF by LC RF is already mature and established in the market LC to add new value to RF Important synergies, both indoors and outdoors offloading, resilience against weather effects RF systems take new opportunities by adding LC Submission Slide 5 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 LC Use Cases in Future IoT Future IoT imaging sensors, video reliable transmission at 100 Mbit/s/device high density of devices latency/jitter constraints Great variety of use cases EU H2020 IA ELIOT (Enhance Lighting for the Internet of Things, 2019-2022, www.eliot-h2020.eu/) Create a new mass market Use cases actually need networked LC, aka LiFi Submission Slide 6 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 IEEE 802 has 3 standards using the light medium IEEE 802.15.7-2019 Optical Camera Communications IEEE 802.15.13 Speciality networks including backhaul (FSO) communications IEEE 802.11bb Mass-market focused complementing WiFi Submission Slide 7 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 IEEE 802.11 offers the best path to mass market success IEEE 802.11 is the world s most common communications standard Over 3.8 billion Wi-Fi chipsets were shipped globally in 2021 in everything from smartphones, TVs, CCTV cameras, baby monitors, etc. The large established market and open standards have created a highly competitive, vibrant ecosystem of devices, testing facilities, etc. Deploying LiFi on a global scale requires reducing the barrier to entry for anyone looking to produce interoperable systems IEEE 802.11 offers the simplest integration route with the highest number of possible device integration options Submission Slide 8 Nikola Serafimovsk (pureLiFi)
March 2023 Operational Concept doc.: IEEE 802.11-23-0283r0 Submission Slide 9 Nikola Serafimovsk (pureLiFi)
March 2023 Implementation Options doc.: IEEE 802.11-23-0283r0 Existing Wi-Fi chipsets Direct Conversion Direct Conversion Up/Down Conversion from RF Up/Down Conversion from RF Submission Slide 10 Nikola Serafimovsk (pureLiFi)
March 2023 doc.: IEEE 802.11-23-0283r0 CCA and LC repetition 802.11bb systems shall have the same requirements for Clear Channel Assessment (CCA) as those for existing Wi-Fi 4, Wi-Fi 5 and Wi-Fi 6 chipsets 802.11bb also suggests the implementation of a LiFi repetition approach where the LiFi AP immediately retransmits the received signal from a STA using Amplify and Forward approach as an example Submission Slide 11 Nikola Serafimovsk (pureLiFi)
March 2023 Spatial Multiplexing and WDM supported doc.: IEEE 802.11-23-0283r0 Wavelength Division Multiplexing => 800nm 900nm => 900nm 1000nm Spatial Multiplexing Submission Slide 12 Nikola Serafimovsk (pureLiFi)
