Estonian Start-Up Reveals World’s Fastest Internet Technology Using LED

November 26, 2015, By Sanjeev Ramachandran

How long would it take to download a HD movie using your high-speed internet? Probably ten to fifteen minutes; that could be the shortest span of time you might have encountered with current technologies.

But if you ever get to use the new technology developed by Velmenni, an Estonian start-up, the duration will get cut short to less than a minute; and that’s why it is being called the world’s fastest internet technology.

It’s called Li-Fi, the LED internet technology that’s coming out to the public after being in development within the lab for over four years.


The work on this high speed internet technology kickstarted back during 2011, after which they successfully tested speeds of 224 Gbps during the early months of this year.

The technology adapted here is the Visible Light Communication, which in its pure form is an advanced form of Morse Code communication.

Similar to the latter technology, Li-Fi also makes use of a flashing light bulb, but it’s that the LED bulbs used in this case flickers much rapidly that it seems unperceivable to human eyes.

Data is transmitted through these flickering light fields that are set in the range of 400 and 800 tera hertz. The net result is that we get a data transmission technology that is 100 times faster than Wi-Fi.

The technology has already been taken out of the labs for testing, during which they were able to clock internet speeds of nearly 1Gbps in office and industrial environments.


But that could be improved when it arrives commercially for office and residential usage, for which the works are already getting triggered by firms like Oledcomm.

Besides, Li-Fi holds its greatest potential in the fact that it makes use of LED bulbs, which are picking up speed in the mission to replace conventional lighting systems. With that said, Li-Fi could easily penetrate to the connectivity area if guided rightly. The same could also make it bloom in the field of connected devices.
