LI-FI

Li-fi record data transmission of 10 Gbps achieved
A Mexican software company has managed to transmit audio, video and Internet across the spectrum of light emitted by LED lamps - at a data transfer rate of 10 gigabytes per second.
The technology can illuminate a large work space, such as an office, while providing full mobile Internet to every device that comes into the range of the light spectrum.
The Li-Fi device circulates data via LEDs that emit an intermittent flicker at a speed imperceptible to the human eye.
"As Wi-Fi uses cables to spread our connections, wireless transmission Li-Fi uses LED lamps that emit high brightness light," said Arturo Campos Fentanes, CEO of Sisoft in Mexico.

Another advantage in comparison to Wi-Fi is that there is no way to hack the signal since the internet is transmitted by light, there is no way to "steal it”.
