LED Lighting Will Deliver Li-Fi Internet Data At 100 Times Fastest Wi-Fi

Delivering data at the speed of light

TN Note: Ubiquitous Internet and data transfer by Wi-Fi will seem like the stone-age when Li-Fi technology rolls out. LED lights are already key factors in the Internet of Things (IoT) and Smart Home technology, and now they will also be able to deliver Internet access at 100 times the speed of Wi-Fi. This will revolutionize and super-charge the implementation of IoT.

Connecting your smartphone to the web with just a lamp — that is the promise of Li-Fi, featuring Internet access 100 times faster than Wi-Fi with revolutionary wireless technology.

French start-up Oledcomm demonstrated the technology at the Mobile World Congress, the world’s biggest mobile fair, in Barcelona. As soon as a smartphone was placed under an office lamp, it started playing a video.

The big advantage of Li-Fi, short for “light fidelity”, is its lightning speed.

Laboratory tests have shown theoretical speeds of over 200 Gbps — fast enough to “download the equivalent of 23 DVDs in one second”, the founder and head of Oledcomm, Suat Topsu, told AFP.

“Li-Fi allows speeds that are 100 times faster than Wi-Fi” which uses radio waves to transmit data, he added.

The technology 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”.
