100x Faster Than Wi-Fi: Li-Fi, Light-Based Networking Standard Released

Proponents boast that 802.11bb is 100 times faster than Wi-Fi and more secure.

Tom's Hardware
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.

it's a feature, not a bug!
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 the walls and stuff are translucent :)

Buildings and stuff aren’t all that translucent to radio waves. You can’t just point two radios at each other with a building between them and expect them to “see” each other. They can bounce and reflect off them like light would off mirrors and reflective surfaces and even be bent by changes in the atmosphere itself, though.

A powerful enough radio, though, is kinda like when you can see light shining through your arm if you hold a flashlight to it.

That’s why I didn’t use “transparent”. Translucent is exactly what they are though, with wood being more see-through and concrete less so. But a regular concrete wall still lets enough through not to drop most connections.

@fearout And wifi Mimo used reflection of the walls to propagate the signal, just like light bouncing off white surfaces and reflecting further away.

Eh. It's less radio transmitters are like flashlights more flashlights are transmitters.

One time, we had remotes for televisions. We hated having to point them to get line of sight.

Did you know that some of the older Gameboys had this? I think it was the Gameboy color. Instead of a link cable, you'd just point two Gameboys at each other, and.... Well, they had to be on a level surface like a table. And also you basically couldn't ever move them or touch them, which was strange for a handheld. ...annnnd it basically didn't work. Ever. So Wi-Fi was pretty good!

But no, let's go and use line of sight tech, that seems like a great idea!

I kid, I kid. I'm sure it works fine enough within its limitations for a certain purpose, I just can't help but joke about making these connections.

I've been at Siemens and saw their Li-Fi lamps, it's pretty cool tech, they use PoE so just one cable for the light and ethernet and then you attach a small receiver to your computer to access the bulb above you.
I dont have problems with speed, i have problems with range...
Kinda curious what the actual use cases for this are. It's not going to replace consumer wi-fi, since walls exist. And we already have light-based transmission within cables (fiber-optic networking). So, is this supposed to provide fast networking to locations where installing fiber isn't feasible? What's the effective range on this?
