Dec 23, 2015: Light Fidelity (Li-Fi) offers a technology that could connect you to the Internet at speeds of 1Gbps, by simply using LED bulbs, free from any waves with any possible harmful effects on the body. Industry experts believe that this technology will gain ground and its demand will pick up in 2016. However, the technology is still in the development phase. It is believed that it would be used first in businesses, and after successful results, in homes.
Industry experts say that as Li-Fi is becoming more commercialized, it will usher in an era of huge business opportunities, such as allowing telecom service providers to reach out to a wider customer base. They say that by 2016, this technology could gain a considerable ground. We can look forward to broader accessibility with Li-Fi Cloud. Smartphones will soon be able to download traffic information from traffic lights or a program guide from a television. This is only the tip of the iceberg. In future, shops will transmit advertisements to your phone as you pass by and bus schedule changes will be transmitted to a screen at the stop. Smarter home appliances that talk machine-to-machine (M2M) are already being extensively researched, where LED lights on electronics function as Li-Fi access points. In fact, the Li-Fi industry is set to become a $6 billion industry by 2018.
Li-Fi is a wireless communication technology that is based on the use of the light spectrum. It sends data by switching the current to LEDs off and on at a very high rate, and is invisible to a naked eye.
Researchers at Oxford University have achieved speeds of 224Gbps in the lab, which is a record. However, it is not likely to become the norm in homes. In France, a number ofl Li-Fi connection experiments are currently underway, mainly in business settings led by major companies like Oledcomm and Lucibel. Estonian start-up Velmenni has already carried out few tests in homes.
It?s quite safe
Li-Fi technology has many advantages, like the absence of radio waves that could be harmful to your health in the long run, and electromagnetic interference. The Li-Fi spectrum is also around 10,000 times larger than Wi-Fi?s, thus making it possible to connect several users simultaneously. Furthermore, since light cannot pass through walls, there can be no automatic connection from one room to another. Above all, it also means that piracy from outside sources becomes simply impossible.
As far as speed is concerned, Li-Fi seems highly promising. It could theoretically achieve speeds of 1Gbps, which is much faster than the most recent Wi-Fi standard (802.11ac).
One of the preconditions for Li-Fi to become a routine is for the entire environment (companies, public places, housing, etc.) to be equipped with LEDs and for mobile phones to have light sensors compatible with this new technology.
