LiFi is a category of Visible Light Communication; an LED light flickers at speeds undetectable to the naked eye to transmit data — a bit like high tech morse code. In fact, scientists have demonstrated in a lab that they can transmit information at as much as 224 gigabits per second, the equivalent of 18 movies of 1.5 GB each being downloaded every single second. In an office setting, they were able to achieve speeds up to 100 times faster than average WiFi speeds.

The LED lights require so little energy, they can be powered by a standard ethernet cord.
