Things are going to get very interesting in the coming months. The way we access internet can completely change forever. Well, that's what scientists are telling us anyway. Remember this word - 'Li-Fi'; it's going to be used very often soon enough.
What is it you ask? Li-Fi is a wireless technology that transmits high-speed (insanely high-speed) data using visible light communication, or VLC.
So imagine switching on a bulb in your room, and it'll not only be a source of light, but will also transmit wireless internet to your phones and other devices. Madness, I tell you. Scientists claim that they are achieving speeds of up to 224 gigabytes per second in the lab using Li-Fi earlier this year. This would mean a revolution in the world of videos.
Now, scientists have taken Li-Fi out of the lab for the first time, testing it in offices and industrial environments in Tallinn, Estonia. They are claiming that they can achieve speeds of up to 1 Gb per second at a work environment. Just to put that into perspective, that is 100 times faster than the average Wi-Fi speeds that we currently have around the world. The technology uses Visible Light Communication (VLC), a medium that uses visible light between 400 and 800 terahertz (THz). It works basically like an incredibly advanced form of Morse code - just like switching a torch on and off according to a certain pattern can relay a secret message, flicking an LED on and off at extreme speeds can be used to write and transmit things in binary code.
