Receiving music or videos on a tablet, a computer or a smartphone, without an internet connection, wi-fi or 3G , but only through the light of a lamp, that's what the Li-Fi technology allows. This technology has existed for several years, it's a technique that uses light sources like a morse code to transmit binary code to a receiver.

But now a group of researchers based in the UK have been able to achieve a transfer rate of 10 gigabit/s record, ten times faster than the fastest fiber optic connections of Google. Such speeds were made possible by the use of micro LED that flashes quickly to communicate in binary code. Researchers have associated red, green and blue LEDs to recreate a white light and increase the amount of information transferred simultaneously.


The technology could replace the wireless Internet connections communicating through radio waves, it has its advantages as well as drawbacks. First of all the connection depends on the amount of light that passes from the LED to a receiver, but still does not require a direct line of sight. You can bounce the signal using mirrors, or even simple walls. Drawback, the connection can not pass through walls or opaque materials. It seeks to create secured areas or limited access.

It's been almost 10 years that different teams were working on Li-Fi technology, earlier this month, a team of Chinese scientists have achieved a speed of 150 megabits only with light bulbs. NASA is also working on its own Li-Fi system based on the use of a high-powered laser that can transmit data at high speed over long distances and to other planets.

can this work in 9ja where they is no light except sunshine?

Blog as source again....

Wow, makes die sense.

My future research project is transmitting data and monitoring object positions via the use of light streams and this article just proves helpful

Bt we no dey get light 4 naija na

i will never be impressed with technology till i can download food

still requires some form of line of sight, even if its scattered or bounced.

calddon: i will never be impressed with technology till i can download food

u are sick

Great but how would it help bring back our girls?

Collinz2: u are sick

m hoping u meant no insult there

Collinz2: u are sick

abeg o

Very impressive I hope it kicks up soon. Can't wait for an Internet speed of 150MBPS, I will download the all the downloadables.

Nice one there.

necessity us truly the mother of invention

nice one

Li-fi keh?
bikonu, Nepa go become god of the universe. u will prefer slapping ur boss to messing with a nepa man

neuljosh: Very impressive I hope it kicks up soon. Can't wait for an Internet speed of 150MBPS, I will download the all the downloadables.

all we do is download
we don't ever thing of uploading
what if the up loaders were thinking like you,what will you have to download.

bloody!

Take a trip to Japan. There are vending machines that will do that for you. The Internet was made for multimedia. Only if can have your belly tweaked into convert media into fibre/starch, then you can have your 'food'. Till then.

Jokes away, Li-fi has been on Its testing phase since 2012 or so by a british Professor. I hope this is going to revolutionize the world and trigger governments around the world to provide electricity for their citizens.

Another invention we should watch out for is Wireless Electricity.

These are the best of times to be alive!

very cool. but am guessing the potential for signal attenuation will be quite high. That means the signal can only be transferred appreciably within a small distance. Cool Idea though. Nice speed

Wireless electricity is already here, in the form of radio waves. search for wireless chargers

Naa, you forgot the speed of light and the pin point ability of laser.

Nasa has been sending data through light rays to space and planets

I feel u. I was just kidding n by the way Li-fi tech is something I have stumbled upon before while I was wild reading.

Lol. Wireless chargers are just subsets of the main invention. How do you like it when you have wireless transformers and no wired poles on the streets?

I know Calddon. Was also joking.

Wireless electricity means nepa go get problem oooo.....them no fit cut light again na.......na only antenna them fit carry run!!!! as for wireless transformer.....people no go gree put phone for ear again becos nepa go strike you die....

What Next? Sci Fi?

It is now official..

NIGERIA IS IN STONE AGE Ooooo

Well, last to Comment

Lol so much lies. How do you intend transferring much more than 10gb per second through led lights? Another hoax news.
Even physical connections are still struggling to achieve that feat let alone LED. Just google the meaning of led and that should show you it's virtually impossible.
