Li-Fi is the new Wi-Fi: First real tests of lightbulb technology find it is 100 TIMES faster than current systems
Step aside, Wi-Fi. Scientists have just taken to the streets with a new wireless technology called Li-Fi, and it's 100 times faster than current speeds.
Li-Fi transmits data using visible light communication, and it's now being tested in offices and industrial environments in Tallinn, Estonia.
This new wireless system hit speeds of 224 gigabits per second in the lab, and has the potential to revolutionize internet usage.
This new wireless system hit speeds of 224 gigabits per second in the lab, and has the potential to revolutionize internet usage. The Li-Fi technology uses visible light between 400 and 800 terahertz (THz), and transmits messages through binary code
Harald Haas from the University of Edinburgh, Scotland invented Li-Fi in 2011.
Haas demonstrated that he could transmit more data than a cellular tower by flickering light from a single LED, according to ScienceAlert.
The system works in a similar way to Morse code, using visible light communication (VLC), but operates at speeds that are too high to be detected by the naked eye.
The Li-Fi technology uses visible light between 400 and 800 terahertz (THz), and transmits messages through binary code, giving it in-lab speeds fast enough to download 18 movies of 1.5 GB each second.
'We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology,' Deepak Solanki, CEO of Estonian tech company, Velmenni, told
Lab tests have shown that Li-Fi can hit speeds 100 times faster than current Wi-Fi systems.
Speed is not the only advantage of Li-Fi.
The system uses visible light communication between 400 and 800 terahertz to transmit messages in binary code.
Visible light cannot pass through walls, making Li-Fi a much more secure system, and less susceptible to interference.
While the system seems promising, it won't likely replace Wi-Fi entirely, at least not anytime soon.
Instead, researchers are now looking to retrofit devices with Li-Fi to use the two wireless systems together to optimize speed and security.
'Currently we have designed a smart lighting solution for an industrial environment where the data communications is done through light.
'We are also doing a pilot project with a private client where we are setting up a Li-fi network to access the Internet in their office space.'
Since the light can't travel through walls, Li-Fi could also be a more secure option down the line, and suffer from less interference from other devices.

The system isn't likely to replace Wi-Fi entirely in the years to come, and ripping out the existing infrastructure isn't feasible.
But the two could be used in partnership to create faster and safer networks.
Instead, researchers are working on retrofitting current devices to be Li-Fi compatible.
PureLifi, a company created by Haas and his team, is offering a 'plug-and-play- application for secure wireless access, ScienceAlert says.
A French tech company called Oledcomm is also working with Li-Fi, and is installing its own system in local hospitals.
Haas says that Li-Fi could combine illumination with wireless data transmission, to make for a cleaner and brighter future.
