More Than 100 Times Faster Than Wi-Fi Li-Fi is a wireless technology that transmits data through the use of Visible Light Communication (VLC). Last month, researchers at the University of Oxford achieve bi-directional speeds of 224 gigabits per second or in layman’s terms, the ability to download 18 movies in one second. Because the data transmission is so fast, the flickering of the light cannot be detected by the human eye. Now, this same group of scientists has taken this test one step fu...
