Wi-Fi now has a rival. Scientists have just taken to the streets with a new wireless technology called Li-Fi, and it's 100 times faster than current speeds.
Li-Fi transmits data using visible light communication, and it's now being tested in offices and industrial environments in Tallinn, Estonia.
This new wireless system hit speeds of 224 gigabits per second in the lab, and has the potential to revolutionize internet usage.
Harald Haas from the University of Edinburgh, Scotland invented Li-Fi in 2011.
Haas demonstrated that he could transmit more data than a cellular tower by flickering light from a single LED, according to ScienceAlert.
The system works in a similar way to Morse code, using visible light communication (VLC), but operates at speeds that are too high to be detected by the naked eye.
The Li-Fi technology uses visible light between 400 and 800 terahertz (THz), and transmits messages through binary code, giving it in-lab speeds fast enough to download 18 movies of 1.5 GB each second.
