Li-Fi is the new Wi-Fi: First real tests of lightbulb technology find it is 100 TIMES faster than current systems System invented in 2011 hits speeds of 224 gigabits per second in the lab Scientists are now testing Li-Fi in offices and industrial environments Li-Fi is uses visible light communication and would be more secure
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. 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
'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…
