Li-Fi is 100 times faster than current Wi-Fi Speeds

Wi-Fi is a now common name which even toddlers can relate to but Li-Fi isn’t. Still in fledgling stage, the new form of wireless technology is confirmed to be more faster than current Wi-Fi speeds and has the potential to be more secured too.

Li-Fi was the first time uses in a real life situation in Estonia a couple of days ago, it was tried out at offices and industrial environments. The new technology which was invented by German Physicist – Professor Harald Haas at the University of Edinburgh in Scotland, uses visible light communication (VLC) and works the same ways as binary or morse codes works.

“Li-Fi is a new wireless technology that transmits high-speed data using Visible light (i.e. Visible Light Communication or VLC) rather than radio bands”. 

When tested in the research lab, scientists achieved a total score of 224Gbps (Gigabits per second) and when tested in Estonia it achieved up to 1GBbps which is about 100 times the current speeds. Unlike Wi-Fi network signals which uses Radio waves, Li-Fi uses Light and can’t penetrate through walls which makes it a more secure option and has very low interference risks.

The new technology is not without its downsides; it cannot be used under direct sunlight as it interferes with its signal and since it cannot penetrate through walls, it would be used in limited or restricted places. There are also subtle issues of light pollution raised.

There is no doubt that Li-Fi is a super-fast alternative to Wi-Fi but is unlikely to replace it anytime soon due to the limited nature of usage. However, researchers are already looking at the chances of retrofitting current Wi-Fi devices to work with this technology.
