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 .
