Currently enjoying Wi-Fi? Get Ready for 100 times faster Li-Fi!!!

You’re probably going to hear a lot about LiFi technology in a few coming months, so it’s better you get acquainted with what it’s all about. In simple words, it is a wireless technology that transmits high-speed data using visible light communication (VLC). Scientists achieved speeds of 224 gigabits per second in the lab using Li-Fi earlier in 2016, that’s 18 movies of 1.5 GB each being downloaded every single second. Now, try to imagine what that kind of internet speed could do for you!

Li-Fi was invented by Harald Haas from the University of Edinburgh, Scotland back in 2011, when he demonstrated for the first time that by flickering the light from a single LED, he could transmit far more data than a cellular tower. Now, it is out of the lab for the first time, and used in offices and industrial environments in Tallinn, Estonia, which have reported that they have achieved data transmission at 1GB per second – that’s 100 times faster than current average Wi-Fi speeds.

“We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology,” Deepak Solanki, CEO of Estonian tech company, Velmenni, told IBTimes UK.

“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.”

The benefits of Li-Fi over Wi-Fi, other than potentially much faster speeds, is that because light cannot pass through walls, it makes it a whole lot more secure. Hence, no more worries about your WiFi being used by unauthorized persons and no specific need for password protected access. Also, as Anthony Cuthbertson points out at IBTimes UK, this also means there’s less interference between devices.

You might be asking yourself now how all that flickering in an office environment wouldn’t drive you crazy; don’t worry – we’re talking LEDs that can be switched on and off at speeds imperceptible to the naked eye.
