Li-Fi Internet

[Osiris199]

Chatanooga Tennessee (and a neighboring town in Georgia), a town in North Carolina, and I believe Minneapolis Minnesota are all rolling out 10 gigabit residential fiber.

I'd imagine there might be 10 or more gigabit connections available in some other countries like South Korea or something as well, I have a hard time believing the fastest residential Internet in the world resides exclusively in the U.S.

Oh ok. Didn't know there were already places where 10 gigabit is planned.

 

I'm aware the US isnt the only country. Norway, Croatia(and surrounding countries), Korea were the ones I was also thinking about, where people have the possibility to access the internet via gigabit.

Its also bloody useless unless you have LOS. Li-Fi cant travel though walls as its in the visible spectrum.

Didn't Lays have a thread for this? Or is it new news about Li-Fi?

Can't seem to find it anymore.

Li-Fi is interesting, but I find no reason it should cause cancer as some people say? Normal lamps don't cause cancer, flickering lamps does not cause cancer, but special flickering lamps should cause cancer?

I expect performance to drop off sharply with distance, due to interference from light pulses bouncing off walls and such. But it'll still be fast. And there can be four channels active simultaneously, namely infrared, red, green and blue. Possibly switching to infrared only if the room needs to be dark. The thing is, light doesn't go through walls, but it does bounce off them, so LOS isn't as critical as you'd think. Another advantage is you get less interference from your neighbour's network. It'll be interesting to see where this goes.
