Bye-Bye Wi-Fi! Go 100 TIMES FASTER With Li-Fi



Internet has changed our lives completely and now the way we access internet is going to change drastically. Earlier, the word Wi-Fi seems to be a part of a sci-fi movie but now it is a very common word and governments are trying to make public places as Wi-Fi zones. Sooner we will be using Li-Fi a lot; it is a wireless technology which transmits data at a very high speed through visible light communication (VLC). So in future, the bulb of your room won’t be a source of light only but it will be a source of internet also for your laptops, tablets, mobiles etc.,
Earlier this year, the scientists have obtained the speed of 224 gigabytes per second using Li-Fi in the lab and now when it is tested in the office environment in Tallinn, Estonia, they have claimed to achieve speed up to 1 Gb per second which is 100 times faster than the speed of Wi-Fi all around the world.
Li-Fi uses visible light between 400 and 800 terahertz (THz) and it works like a highly advanced form of Morse code as switching a torch on and off to convey a message secretly, in the same way, it is possible to write and convey things in binary code by flipping a LED on and off at extreme speeds.
“We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology,” as told to IBTimes UK by Deepak Solanki, CEO of Estonian tech company, Velmenni.
He further added, “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 space.”

Li-Fi was invented in 2011 by Harald Haas, University of Edinburgh, Scotland, Haas says that not just speed but this technology has many benefits. You don’t need to worry about your data being used by your neighbour as light is not capable of passing through walls, so no risk of stealing.
Despite the fact that Li-Fi is very fast in comparison to Wi-Fi, experts feel that Wi-Fi and Li-Fi, used together in coordination will give better and secure networks.
Haas said “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. 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.”
So when Li-Fi comes to India, everyone with an LED bulb will have access to internet.
