Li-Fi Gives 100 times Faster than Wi-Fi

Internet has changed our lives completely and now the way we access the Internet will change dramatically. Earlier, the word Wi-Fi seems to be part of a sci-fi, but is now a very common word and governments are trying to make public places such as Wi-Fi zones. Soon we will be using Li-Fi lot; It is a wireless technology that transmits data at a very high speed through the visible light communication (VLC). So in the future, the bulb of your room is not only a source of light but is also a source of Internet for their laptops, tablets, mobile phones, etc.,

Earlier this year, scientists have obtained the speed of 224 gigabytes per second using Li-Fi in the laboratory and now when tested in the office environment in Tallinn, Estonia, they claimed to reach a speed of up to 1 Gb per second, which is 100 times faster than the speed of Wi-Fi worldwide.

Li-Fi uses visible light from 400 to 800 terahertz (THz) and works as an advanced form of Morse code as changing a torch on and off to transmit a message in secret, in the same way, you can write and transmit things in binary code to launch an LED on and off at extreme speeds.

“We’re doing some pilot projects in various industries in which we use the VLC (visible light communication) technology,” as told IBTimes UK by Deepak Solanki, CEO of technology company in Estonia, Velmenni.

He added, “Today we have designed a solution of intelligent lighting for industrial environments where data communication is performed through the light. We are also doing a pilot project with a private client where we are creating a network of Li-Fi Internet access in your office space. ”

Li-Fi was invented in 2011 by Harald Haas of the University of Edinburgh, Scotland, Haas says that not only speed but this technology has many benefits. You do not have to worry about your data being used by your neighbor as light is unable to pass through the walls, so there is no risk of theft.

Despite the fact that Li-Fi is very fast compared to Wi-Fi, experts believe that Wi-Fi and Li-Fi, used together in coordination will give better and secure networks.


Haas said: “All we need do is fit a small microchip to every potential illumination device and this would then combine two basic functions. Illumination and wireless data transmission in the future not only going to have 14 billion bulbs, we can have 14 billion Li-Fi’s deployed worldwide to an even brighter, “greener and cleaner future.

So when Li-Fi comes to India, each with a LED bulb will have internet access.
