New wireless technology has been tested that is 100 times stronger than Wi-Fi.
It is called Li-Fi and it could revolutionise the way we interact online.
The
technology, which transmits information using visible light
communication, is being tested in offices and other workplaces in
Tallinn in Estonia.
Tests
in the lab have revealed that Li-Fi can be up to 100 times quicker than
Wi-Fi - it uses visible light and transmits messages through binary
code.
Because visible light cannot pass through walls, it is thought the system will be more secure.
But
there are no plans to replace the Wi-Fi we know and love and sometimes
hate just yet - researchers want to combine the two technologies
together.
Li-Fi
was invented in 2011 by Professor Harald Haas from the University of
Edinburgh; he showed that more data could be transmitted than a cellular
tower by flickering light through a singled LED.
Researchers
have reported that, in recent tests, Li-Fi has achieved data
transmission of 1GB per second, making it 100 times faster than Wi-Fi.
Its lab record of 224 gigabits per second mean it could download 18 movies of 1.5GB each every second.
“We
are doing a few pilot projects within different industries where we can
utilise the VLC (visible light communication) technology,” Deepak
Solanki, chief executive of Estonian tech company, Velmenni, told the International Business Times.
“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.”
Other companies, including one created by Professor Haas and a French firm, are working to bring Li-Fi to the public.
