LiFi: What is it?

What is "LiFi"?

Prof. Harald Haas coined the term "LiFi" at his TED Global talk to describe the high speed, bidirectional, networked and mobile wireless communication of data using light.

This is what he envisioned.....

Saw his presentation at OFC 2015, fascinating stuff.

As a gamer i have only one question, will this remove lag?

[Oaklev]

How about uploading? Is my smart phone supposed to have an LED in it, too?

[danik]

very interesting technology . but how the data will be transferred outside of the lamp ? through an electrical network?

[samritnarshing]

will it work.. under the table???.. i don't want to be seen when during chatting

[smujismuj]

My guess is that Capitalists will do everything in their power to make this exclusive, and expensive, or to make it illegal so it won't be competitive with current technology.

[tifftom]

What are any negative health side effects from LiFi ? And if so, how would you know the long term effects on humans/animals since it’s so new to the market?

Bigger, better, faster, more revolutionary tools for Big Brother and his IoT.

I'm already made li-fi system for my university project it's amazing

Install it on the sun OMG FREE LIFI/WIFI TO THE HOLE WORLD

THe only thing is the internet is so fast already with fiber etc... i wonder if there would be a real benefit im shure the vidoes would be more alive and have way better streaming qualities but to get basic information the speed we have now is pretty fast im wondering what would this bring to a person on wifi with good speed at this time.

[Bezle]

I'm confused. So it can deliver speeds of up to 1GB but it's 100 times faster than wifi even though the maximum speed of 802.11ac is 1.3Gbps? I clearly have some facts wrong, could somebody care to elaborate for me please.

[estefan]

Nice idea, What we need is routers at 10w 50w, and 100w. Long distance WiFi networking, that an omni-directional for 3-4 miles.

[chun]

That would be better to have a adapter with LAN port output, or LiFi to Wifi AP. Something like a homeplug.

[Horsefeathers]

WARNING Dr Haas... Radio Shack had circuits, in the 1990s, in their electronics manuals using LEDS to send signals.

[RumbleGaming]

This is technically fiber, but through the air.

[wackydawgcoptyltd]

So if I'm in bed at night and want to use my phone, do I leave the light on all the time ?

[mohanmohanmiah]

The world is ending soon li-fi is coming

[ExplosiveMareeps]

And so what is stopping me from shining an LED light to intercept someones data at a phone?

[kenjboyd]

LiFi is so superior to WiFi, it is definitely the future of networking, & full wireless w/no microwaves!
