PureLiFi is recognized as the leader in visible light
communication (VLC) – the use of the visible light spectrum instead of
radio frequencies to enable wireless data communication. In collaboration with
technology and solutions providers, pureLiFi technology will provide ubiquitous
high-speed wireless access that offers substantially greater data densities
than Wi-Fi along with inherent security properties that eliminate unwanted
external network intrusion. In addition, the integration of illumination and
data services generates a measurable reduction in both infrastructure
complexity and energy consumption.
The use of
light bulbs for wi-fi connectivity is one step closer according to new findings
from Chi Nan, an IT professor at Shanghai’s Fudan University.
a micro-chipped bulb has the ability to produce data speeds of up to 150 megabits per second (Mbps). Researchers claim that a one-watt LED light bulb would provide net connectivity to four computers.
However there has been no supporting video or photos to back these claims up, sparking questions as to the validity of the findings.
Back in 2011,
Professor Harald Haas from the University of Edinburgh demonstrated how an LED
bulb fitted with signal processing technology could stream high-definition
video to a computer. Following that he created the term “light fidelity” or
li-fi and set up a company named PureVLC in order to make use of the
technology.A spokesperson from PureVLC said of the latest findings: “We’re just as surprised as everyone else by this announcement, but how valid this is we don’t know without seeing more evidence. We remain sceptical.”

A one-watt LED light bulb would be enough to provide net connectivity to four computers, researchers say.
Li-fi, also known as visible light communications (VLC), at these speeds would be faster - and cheaper - than the average Chinese broadband connection.

"But how valid this is we don't know
without seeing more evidence. We remain sceptical."This year, the Fraunhofer Heinrich Hertz Institute claimed that data rates of up to 1Gbit/s per LED light frequency were possible in laboratory conditions, making one bulb with three colours potentially capable of transmitting data at up to 3Gbit/s.
