Superfast Internet Connection On The Horiozon As Li-Fi Proved To Be 100 Times Faster Than Wi-Fi

Revolutionary technology, dubbed Li-Fi, could signal the end of the Wi-Fi era.

Tested in Tallinn, Estonia it transmitted data at 1GB per second - that is 100 times faster than current average Wi-Fi speeds, Science Alert reported.

In practical terms, this means Li-Fi will allow you to download a high-definition film within a matter of seconds. Sweet.

The tech uses a Morse code-esque mechanism in which turning an LED on and off at a high-speed can transmit data in a binary code.

Known as Visible Light Communication (VLC), this medium requires light between 400 and 800 terahertz.

If you are concerned Li-Fi will turn your office or house into a club, don't worry - the flickering happens at such a fast rate that you won't be able to see it with the naked eye.

One of the main advantages that Li-Fi has over Wi-Fi is that it can not pass through walls and therefore, the signal is stronger and the chance of interference is less.

The tests were carried out by a firm known as Velmeni in New Delhi, India.

CEO, Deepak Solanki, told IBTimes UK: "We are doing a few pilot projects within different industries where we can utilise the VLC technology.

"Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light.

"We are also doing a pilot project with a private client where we are setting up a Li-Fi network to access the internet in their office."

Li-Fi was first invented by Harald Haas, who showed the world that he was able to transfer more data than a cellular tower through the use of LED lights.

In 2011 he gave a TED Talk answering the question: What if every light bulb in the world could also transmit data?

"All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission," he said.

"In the future we will not only have 14 billion light bulbs, we may have 14 billion Li-Fis deployed worldwide for a cleaner, greener and even brighter future."
