Light Fidelity or LiFi is a new scientific breakthrough which promises to make our phones and laptops a lot faster. It is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds. Li-Fi is a transformative technology changing the way we connect to the internet by using the same light we use to illuminate our offices, home and even streets. LiFi uses visible light from LED bulbs to transfer data, rather than WiFi’s radio waves and could be 100 times faster than Wi-Fi. It utilizes LED lights that illuminate both our workspace and homes to transmit high speed, bidirectional, secure and fully networked wireless internet.
Chinese scientists have come closer to develop this faster wireless
communication channel that would be accessible in the next six years.
They have already made progress in creating full-colour emissive
carbon nanomaterial dots (F-CDs) to provide the light to transmit data.
The latest research going on related to Li-Fi uses rare earth materials
to provide light, but Chinese experts have come up with another option,
F-CDs, a fluorescent carbon nanomaterial to provide light. This method
is safer, reliable and faster. “Many researchers around the world are
still working on this. We were the first to successfully create it using
cost-effective raw materials such as urea with simple processing,” Qu
Songnan, an associate researcher at Changchun Institute of Optics said.
Qu informed that as the rare earth has a longer lifespan it diminish the
speed of Li-Fi transmission. F-CDs, on the other hand, provides faster
transmission of data. New nanomaterial introduced by Qu’s group of
scientists can emit all light visible to the human eye. This is an
innovative development in fluorescent carbon nanomaterial field. Qu
further added that this breakthrough this essential in the development
of Li-Fi which he anticipates will enter the market in the next six
years.
Chinese tests in 2015 showed that Li-Fi can reach speeds of 50 gigabytes
per second. The technology began to make waves after scientist Harald
Haas of the University of Edinburgh discussed it in a 2011 TED talk. It
has been viewed 2.2 million times. Technologies based on Li-Fi are
currently being developed by several companies in Russia, Mexico and
around the world. Li-Fi offers lighting innovators the opportunity to
enter new markets and drive completely new sources of revenue by
providing wireless communications systems. Li-Fi is a game changer not
only for the communications industry but also for the lighting industry,
and with LiFi, Linmore LED certainly has a brighter future. There’s no
doubt that LiFi is going to transform the world of Internet
connectivity, but it seems unlikely that its rise would necessarily mean
the death of Wi-Fi since the latter is deeply embedded in the
lifestyles of billions of people. A more likely scenario would be that
we’ll eventually have a wide range of technologies available at our
disposal and will be free to choose the most appropriate one.
