Do you like Wi-Fi? You are going to love Li-Fi. <br /> <br />While Wi-Fi is short for Wireless Fidelity, like good old Hi-Fi and High Fidelity, Li-Fi stands for Light Fidelity. Fidelity of transmitting information and data, through light. <br />For a bit of background, this term Li-Fi was first proposed in 2011 by a professor of mobile communications at Edinburgh University (Scotland) during a TED conference. <br />However, history fans would say the first demonstration of Li-Fi communications dates back to…1880, when Alexander Graham Bell, inventor of the telephone, unveiled his photophone, a device that could transmit the sound of his voice over several hundred meters using sunlight. <br /> <br />Today, the development of Li-Fi is linked to the development of light-emitting diodes or LEDs. <br />In 60 seconds, you will know everything!
