Dubai-based telecommunications provider, Du and Zero1 are testing the technology. Du already claims to achieve success in providing internet, audio and video streaming over a Li-Fi connection.
" 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 said.
" 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.”
The Li-Fi market is anticipated to have a compound annual growth rate of 82 % from 2013 to 2018 and to be worth over $ 6 billion per year by 2018.
' We are going to connect our coffee machine, our washing machine, our toothbrush. But you can ' t have more than ten objects connected in Bluetooth or Wi-Fi without interference,' said Suat Topsu, founder, and head of Oledcomm.
Li-Fi v / s Wi-Fi
Li-Fi with its 224 gigabits per second might be the fast hare in the race of data transmission, leaving Wi-Fi behind, however certain cons still gives the Wi-Fi edge ahead of Li-Fi.
Li-Fi has almost no limitations on capacity. The visible light spectrum is 10,000 times larger than the entire radio frequency spectrum.
Researchers have reached data rates of over 224 Gbit / s, which is much faster than typical fast broadband in 2013. Li-Fi is expected to be ten times cheaper than Wi-Fi.
" 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," Haas said. " In the future, we will not only have 14 billion light bulbs, we may have 14 billion Li-Fis deployed worldwide for a cleaner, greener, and even brighter future."
In October 2011, the Li-Fi Consortium was formed by the companies and industry groups, to promote high-speed optical wireless systems and to overcome the limited amount of radiobased wireless spectrum available by exploiting a completely different part of the electromagnetic spectrum.
However, this doesn’ t indicate that Li-Fi will completely replace Wi-Fi in the coming times. The endeavor is to work together with the two technologies, to achieve more efficient and secure networks.
According to Gartner chief analyst Jim Tully, Wi-Fi will continue to evolve and improve its own capabilities, and this could determine how the role of Li-Fi moulds in.
It is estimated that by 2019, roughly 35 quintillion bytes of information every month will be generated and exchanged globally. With the escalating demand for faster and more efficient wireless networks, with IoT knocking and entering the communication threshold, the future is bright for Li-Fi as a reliable, affordable and more secure solution.
