The newly invented Li-Fi Internet technology is 100 times faster than Wi-Fi and promises to revolutionize telecommunication, in an almost magical way.
The wireless system has been developed by an Estonian startup called Velmenni, and now the company is trying to find ways to make it commercially available, and turn it into a modern-day fixture.
The technique, which has been named Jugnu, channels the power of light through LED bulbs, featuring Li-Fi chips. This means of conveying binary data back and forth is a major departure from current networking technologies that are based on radio waves.
The next-generation LED bulbs developed by Velmmeni are capable of sending data to other similar bulbs and mobile devices, using visible light communication (VLC), between 400 and 800 terahertz (Thz).
The unprecedented efficiency of this new technology translates into data transfer speeds of around 1 Gbps, approximately 100 times higher than those achieved by Wi-Fi. In other words, a high-definition motion picture could be downloaded in just a handful of seconds.
While this may sound futuristic, in fact during lab experiments conducted ever since 2011, when the wireless technique was initially masterminded, researchers were able to obtain data transmission rates of up to 224 Gbps.
One disadvantage is the fact that Li-Fi isn’t effective while under direct sunlight, unless filters are used, and it’s also only designed for indoor use, which means that public Wi-Fi networks will remain unchallenged.
Another downside is that Li-Fi signals can’t seep through walls, so every room would have to be equipped with its own Jugnu source.
On the other hand, the limited scope of the signal would reduce the likelihood of someone else stealing the consumer’s Internet, and using their precious bandwidth without their knowledge or approval.
Moreover, as International Business Times reporter Anthony Cuthbertson explains, getting a wireless connection using bulbs instead of ordinary devices would eliminate the issue of interference.
This phenomenon which reduces Internet speeds and makes connections less stable appears when several network devices are trying to access one particular channel.
At the moment, start-up employees are working on an Android app which would allow mobile devices to receive data using the LED bulbs.
More precisely, the focus is on workplaces and industrial environments, which will incorporate smart lighting not just as a source of illumination, but also as a means of conveying information across private Li-Fi networks.
During pilot tests carried out in Tallin, Estonia, it was proven that data can indeed be transmitted to devices at speeds reaching 1 Gbps, just through LED lights that flicker intermittently, within nanoseconds.
The ultimate goal now is to develop the technique which would allow bi-directional data transfer, so that users can also send information translated into binary code using Jugnu.
However, lead developer Harald Haas from the University of Edinburgh, Scotland, believes that this state-of-the-art, alternative technology doesn’t actually have the potential to render Wi-Fi obsolete in the immediate future.
This is because such a transition would entail replacing all the incandescent sources of electric light (such as light bulbs and lamps) with smart LED bulbs.
Nevertheless, this type of technology definitely has huge potential, given that it’s much more environmental-friendly, energy-efficient and economic.
Basically, it would satisfy two modern necessities simultaneously: the need for electricity, as well as the desire to stay connected with others using telecommunications.
It could also be instrumental in creating “The Internet of Things”, by connecting gadgets together, and allowing them to seamlessly interact with one another.
Therefore, maybe in the long run, as more individuals strive to turn their dwelling places into smart homes, Jugnu-based LED technology might indeed supersede light bulbs entirely, while at the same time turning Wi-Fi into a thing of the past.
