#Innovation – Beyond Wi-Fi: Li-Fi faster and secure communications

10/1/2017

 
Li-Fi technology replaces radio frequency bi-directional communications from your Wi-Fi router by using light modulated fluorescent tubes or LED lamps similar to the LED lights already in use at the workplace or at home.
Light pulses issued from the digital data of a text message, video or email modulates the Light Emitting Diode (LED). The rate of change of the LED light is so fast that although now it contains a digital signal the lights are not flickering and the modulation is not perceived by the naked eye.
It increases the speed of uplink/downlink wireless transmission (download a video, Skype video call) between the server and a laptop computer, tablet, or smartphone providing an extremely high bandwidth. It can also protect the communication from eavesdropping if the light source is contained inside the building.
The headquarters of Microsoft in Paris and other companies already are using Li-Fi communications.
