If you haven’t heard, there’s a new wireless Internet technology that leaves Wi-Fi speeds in the dust. Li-Fi, which is short for Light Fidelity, was created in 2011 by Harald Haas of the University of Edinburgh in Scotland. The technology is an LED-based alternative to Wi-Fi described by Science Alert as an “incredibly advanced form of Morse code.” Scientists of Estonian tech company Velmenni have now tested Li-Fi in a real-world environment, where it proved to be 100 times faster than Wi-Fi.
Li-Fi technology works through Visible Light Communication, using visible light from 400 to 800 terahertz to transport data at high speeds. The Li-Fi test run, which took place at Velmenni’s offices in Tallinn, Estonia, resulted in a few promising revelations about how the fully networked high-speed communication technology performs in the real world. During the trial, scientists clocked Li-Fi at a top speed of 1GB per second, breaking the previous record of 224 gigabits per second held by Wi-Fi. What’s more, the trial also confirmed that Li-Fi technology is significantly more secure than Wi-Fi. This is because light, and in this case the data that it carries, can’t travel through walls.
Discussing the new Li-Fi trial with IBTimes UK, Velmenni CEO Deepak Solanki states, “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.” Though the results of the Li-Fi trial have been stellar thus far, don’t start counting down to the demise of Wi-Fi just yet. Due to the high costs of replacing Wi-Fi, it wouldn’t be pragmatic to get rid of it and implement Li-Fi across the board. Instead, scientists are working on a way to make our mobile devices Li-Fi-compatible. The two technologies could potentially be combined in the future to form a single, more secure wireless technology.
