Move aside Wi-Fi, there's a new super-fast wireless internet coming called Li-Fi

[Sarkar]

Scientists have developed a new form of wireless communication for computers that is 100 times faster than Wi-Fi.

Called Li-Fi, it's a wireless internet technology that rapidly transmits data using flickering LED light fields between 400 and 800 terahertz. It's a process known as Visible Light Communication, which is like an advanced form of morse-code which, much like switching a torch on and off in a pattern that relays a message, the LED light flicks on and off at such extreme speeds that it can be used to write and transmit things in binary code.

Researchers at Estonian hardware start-up Velmenni successfully tested the technology in a commercial context, trialling it in offices and industrial environments in Tallinn, Estonia, reporting transmission speeds of 1 gigabits per second, 100 times faster than current average Wi-Fi speeds.

"We are doing a few pilot projects within different industries where we can utilise the VLC (visible light communication) technology," chief executive Deepak Solanki told IBTimes UK

"Currently we have designed a smart lighting solution for an industrial environment where the data communication 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."

Move over Wi-Fi, here comes Li-Fi (100 times faster)

A new type of wireless internet technology
has been developed that could provide a
connection that's 100 times faster than
traditional WiFi.
. . The tech is called LiFi, and was tested by an
Estonian start-up called Velmenni, who are
currently trialling it in offices.
. . LiFi has proved capable of sending data at
speeds of up to 1GBps, around 100 times
faster than most current Wi-Fi connections.
. . At speeds like this, albums, high-definition
films and even video games could be
downloaded in a matter of seconds.
. . The speed is down to the way in which it
transmits data -- by using Visible Light
Communication (VLC), data is sent between
networks by LED lights that flicker incredibly
fast.
. . The technology does have one major
limitation -- because it relies on visible light
to work, it can't 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.
. . Professor Harald Haas, from the University
of Edinburgh, pioneered the technology and
coined the term LiFi in 2011, but this is the
first time it's been used in a 'real world'
setting.
. . Deepak Solanki, CEO of Velmenni, told the
Interational Business Times that the
technology could be rolled out to consumers
within the next three to four years.
. . However, due to LiFi's limitations, it would
be likely to run in parallel with existing
technology to increase a network's speed and
efficiency.
. . 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."
. . "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."

RE: Move over Wi-Fi, here comes Li-Fi (100 times faster)

A new method of delivering data, which uses the visible spectrum rather than radio waves, has been tested in a working office.

Li-fi can deliver internet access 100 times faster than traditional wi-fi, offering speeds of up to 1Gbps (gigabit per second).

It requires a light source, such as a standard LED bulb, an internet connection and a photo detector.

It was tested this week by Estonian start-up Velmenni, in Tallinn.

Velmenni used a li-fi-enabled light bulb to transmit data at speeds of 1Gbps. Laboratory tests have shown theoretical speeds of up to 224Gbps.

It was tested in an office, to allow workers to access the internet and in an industrial space, where it provided a smart lighting solution.

Speaking to the International Business Times, chief executive Deepak Solanki said that the technology could reach consumers "within three to four years".

The term li-fi was first coined by Prof Harald Haas from Edinburgh University, who demonstrated the technology at a Ted (Technology, Entertainment and Design) conference in 2011.

His talk, which has now been watched nearly two million times, showed an LED lamp streaming video.

Prof Haas described a future when billions of light bulbs could become wireless hotspots.

One of the big advantages of li-fi is the fact that, unlike wi-fi, it does not interfere with other signals, so could be utilised on aircraft and in other places where interference is an issue.

While the spectrum for radio waves is in short supply, the visible light spectrum is 10,000 times larger, meaning it is unlikely to run out any time soon.

But the technology also has its drawbacks - most notably the fact that it cannot be deployed outdoors in direct sunlight, because that would interfere with its signal.

Neither can the technology travel through walls so initial use is likely to be limited to places where it can be used to supplement wi-fi networks, such as in congested urban areas or places where wi-fi is not safe, such as hospitals.
