Li-Fi 100x Faster THan Wi-Fi.

Li-fi, short for “light fidelity” (a term coined by professor Harold Hass in a TED talk in 2011) has lightning speed. It uses the frequencies generated by LED bulbs — which flicker on and off imperceptibly thousands of times a second — to beam information through the air, leading it to be dubbed the “digital equivalent of Morse Code”. Li-fi was demonstrated at the Mobile World Congress, in Barcelona, with a Smartphone placed under an office lamp, and it started playing a video. Laboratory tests have shown theoretical speeds of over 200 gbps — fast enough to download the equivalent of 23 DVDs in one second. Li-fi allows speeds 100 times faster than wi-fi which uses radio waves to transmit data. Dutch medical equipment and lighting group Philips is reportedly interested in the technology and Apple may integrate it in its iPhone7.
