But when people began understanding that we’re not arguing for Li-Fi against Wi-Fi, but claiming a complementary use, they really began seeing the benefits of using light.”
The standard was developed for Li-Fi to work alongside Wi-Fi ... Li-Fi simply appears as if it was another band of Wi-Fi ... We are enabling interoperability of Li-Fi and Wi-Fi, positioning Li-Fi as a complementary and additive technology to the existing ecosystem.</code></pre>
I cannot but feel that some part of the spectrum that is invisible, so it can work when the light is turned off, and is capable of penetrating the walls so as to not require an expensive wired repeater in every room, would still remain the best choice for providing local connectivity in general.<p>I can see applications for LiFi, but it will not replace WiFi any time soon.

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.</i>
Interestingly, optical was one of the PHYs for the original 802.11: indirect (diffuse) infrared. I think the idea was that the AP and the individual nodes would communicate by scatter off the office ceiling.<p>(The other two PHYs were FHSS and DSSS on 2.4GHz, the latter of which morphed into the 802.11b that gained wide popularity.)
