> The new standard for Li-Fi, IEEE 802.11bb, is designed to provide a global framework to deploy light-based devices that are compatible with each other. It was ratified in June [2023] ... Li-Fi simply appears as if it was another band of Wi-Fi ... It can achieve data rates of 1 Gbps or more from a range of 20 centimeters to 3 meters.
- londons_explore 3y agoI would hope for bandwidths much higher than 1Gbps... Assuming conservatively you can do 1 bit/sec/Hz, we should be able to get an easy 300 Tbps in the visible light spectrum. Any thats a low estimate, because physics lets you do massive MIMO, polarization, etc to get even more throughput.

- bloggie 3y agoWe are currently seeing 200 Gbps sat-to-ground but Li-Fi is targeting much lower bandwidth, as the application is different. https://www.nasa.gov/centers-and-facilities/ames/nasa-partners-achieve-fastest-space-to-ground-laser-comms-link/ https://www.nasa.gov/centers-and-facilities/ames/nasa-partne...
