Proponents boast that 802.11bb is 100 times faster than Wi-Fi and more secure.
Isn’t WiFi technically light based? It’s all just electromagnetic radiation
Radio.
Radio and light are the same thing from a physics standpoint, just different ranges of electromagnetic spectrum.
So phones and communication towers are basically flashlights blinking at each other using invisible light, to which walls/buildings and stuff are translucent :)
Or like x-ray is pretty much a camera flash that can shine through bodies.
Won’t light based wi-fi have problems penetrating walls? I did not see that point brought up in the article.
Its sort of indirectly mentioned when they mention the security benefits of lifi, as in order to effectively have access to it, you would need access to the room.
The tech isnt meant to completely replace wifi, it just jas some benefits in certain use cases over wifi.
