The visible light communication (VLC) technology allows data to be transferred through smart LED bulbs instead of traditional radio frequencies (WiFi) at the speed of up to 224 gigabits per second.

New Dehli and Tartu-based startup Velmenni is the first to trial the LiFi technology, invented by University of Edinburgh Professor Harald Haas in 2011, in the real world, in the offices and industrial environments in Tallinn, International Business Times reported.

"Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through light. We are also doing a pilot project with a private client where we are setting up a LiFi network to access the internet in their office space," Deepak Solanki, CEO of Velmenni, told IBTimes.

The success of the pilot projects could see LiFi technology rolled out for consumers within the next three to four years, Solanki added, allowing people to access the internet using the light bulbs in their home.

The system works much like the Morse code and transmits messages through binary code. Yet it works on such high frequencies that the transmission is 100 times as fast as with WiFi. It is also greener and a more secure alternative to the latter.
