How you could soon be surfing the web via lights

A inventor from Germany has claimed a major breakthrough in revolutionising how we access the internet.

Harald Haas is the man behind LIFI – a technology which allows internet data to be sent and received via LED lights.

His company, Pure LIFIhas recently released a USB dongle device that enables laptops and tablets to be connected to the burgeoning technology.

“I think it’s not a question of if, it’s a question of when,” Haas told Euronews. “LIFI is a necessity and it will come.

“This is dongle is a real breakthrough that allows us to engage larger scale projects. The pilots we have equipping a number of office environments but now we can equip a full floor of a hotel or an airport.”

How does it work?

Signals are sent via the light stream – at frequencies the human eye cannot detect – to sensors on your device and vice-versa.

But, how does the internet get into the light source?

Haas says there are two solutions and both involve sending data signals down the same cable as the light’s power source.

What is Li-Fi Internet

Light Fidelity (Li-Fi ) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas  and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or Cellular network), or even a replacement in contexts of data broadcasting. It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second.

It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.
