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.

Plans to test 5G technology to provide wireless connectivity before the end of 2016

It is held to be ideal to support bandwidth-hungry applications around video, virtual and augmented reality and the internet of things (IoT), because it will support multiple radio interfaces and use radio spectrum much more efficiently.

“Experiences such as virtual reality, self-driving cars, robotics, smart cities and more are about to test networks like never before,” said AT&T chief strategy officer and group president of technology and operations John Donovan.
