New Internet Tech That's 100 Times Faster Than WiFi

Scientists have come up with a new type of wireless internet technology that is said to be 100 times faster than traditional WiFi. The tech is called LiFi, and was tested by an Estonian start-up called Velmenni, who are currently looking at trialing it in the enterprise.

The pilot testing of LiFi, an alternative technology to WiFi has proved that it is  capable of sending data at speeds of up to 1GBps, according to a report in The Telegraph UK. LiFi uses light to beam information through air. 

The technology was first discovered by Professor Harald Haas in 2011 of the University of Edinburgh, but this is the first time it’s been used in a ‘real world’ setting. By using Visible Light Communication (VLC), data is sent between networks by LED lights that flicker incredibly fast.

The report also said that the technology could be rolled out for users in the market in another three to four years, Deepak Solanki, CEO of Velmenni, told the Interational Business Times. At speeds like this, albums, high-definition films and even video games could be downloaded in a matter of seconds, he said.

The technology does have one major limitation. It relies on visible light to work, and it cannot pass through walls. However, this makes the network much more secure. The dramatically increased speeds make it a big improvement on current technology for some applications as well.

While LiFi may not completely replace WiFi, the technologies could be used in parallel to create more efficient networks, believe experts. However, if the infastructure catches up, LiFi could become much more widely used, especially if it’s transmitted through our lightbulbs, as Professor Haas suggested in a 2011 TED Talk.

As Haas said, “All we need to do is fit a small microchip to every potential illumination device and this would then combine two basic functionalities: illumination and wireless data transmission.”

He believes, “In the future we will not only have 14 billion light bulbs, we may have 14 billion LiFis deployed worldwide for a cleaner, greener and even brighter future.”
