Today , we know the WiFi to access data without using a cable. Perhaps soon we will use the li -fi, which works on the same principle, but based on reading
Mière . It was presented at the LeWeb 2012 show.
Developed by Suat Topsu , University of Versailles Saint Quentin en Yvelines, Li- fi ( for Light - Fidelity ) is based on a system similar to Morse code. Put the machine near a light source , and it will flash imperceptibly to transmit information such as videos or text messages .
For now, this technology is in the experimental stage , but it already has a lot of quality . Already , the information transmitted is not harmful to humans, since it is that light . In addition, it allows to transmit information to a specific location.
A technology that has a future , and that may be required in future years in public places . For example , advertisers are interested in Li -Fi to integrate them into billboards, and then send the data to the people around . This technology is not thinking exclusively in France . Japan and the United States are also working on.
