LiFi: Communication at the speed of light and the emergence of the Internet of people

Without light there would not be life. But light will change the world once more. In 1880 Graham Bell made-in his own words-his greatest discovery: the photophone. Bell succeeded in transmitting sound over the waves of sun light. Bells problem: the sun does not always shine. 125 years later French physicist Suat Topsu was able to apply Bells innovation to LED lighting and LiFi-Internet over light waves-was born.LiFi is much faster. It is healthier because it does not interfere with our bodies. LiFi cannot be hacked and it does not require massive investments: the public light infrastructure already exists! Cities can save money replacing lights with LiFi enabling LED lights. LiFi also offers an opportunity to redesign online communication in the interest of the common good. While the Internet of Things is fast emerging LiFi points the to an even more exciting future: the Internet of People.
