Technology is amazing. There is always the question of...what's next? A French start-up company called Oledcomm demonstrated a new technology called Li-Fi that promises Internet access 100 times faster than Wi-Fi with revolutionary wireless technology.

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".

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

Li-Fi 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".

It is rumored that Apple is possibly looking to integrate Li-Fi into its next smartphone, the iPhone7, due out at the end of the year, according to tech media.

It will be interesting to see how well Li-Fi will be accepted!
