With an increasing demand for reliable internet connections, innovators have hard sleepless nights trying to come up with new solutions that would revolutionize the Internet of Things otherwise known as #IoT. One such solutions that could soon be available for public use if Li-Fi; short for ‘light fidelity,’ which uses beams of light to transmit internet connections.
INTERNET AT THE SPEED OF LIGHT
The technology which emerged from the laboratories in 2015 and tested by a French start-up Oledcomm, has been proven to have speeds that are 100 times faster than Wi-Fi. While demonstrating the technology at the Mobile World Congress in Barcelona this week, the French firm had a video played on a smartphone using an office lamp, which carried radio waves that are used by Li-Fi to transmit data.
The technology is also said to be using a visible light communication (VLC) of between 400 and 800 terahertz (THz) to transmit messages in binary code operating at such a supersonic speed that cannot be detected by a naked human eye. Suat Topsu, founder and head of Oledcomm has been quoted by the AFP news agency as having said that with speeds of up to 200 Gbps, Li-Fi was fast enough to ‘download the equivalent of 23 DVDs in one second.’
The uptake of Li-Fi technology is however going to prove to be difficult as devices will have to be equipped with a card reader, or dongle, to work with the technology.
This despite Apple having shown interests to integrate it in the iPhone 7 due to be released to the market by the end of the year. The technology also faces a challenge of its inability to pass through walls since the technology is restricted to boundaries within which the LED beams fall.
Li-Fi MAKES SENCE
Deric Karunesudas however thinks differently. According to Deric, it was time the world moved to another level of internet connectivity. “Oil of spectrum is running out…Hence #Li-Fi makes sense,” remarked Deric through his twitter account.
This level of optimism could however prove to be too much of good tidings to be believed by some and for this category of people, it wouldn’t hurt to just wait and see how things turn out.
Among key advantages of Li-Fi is the ability to restrict its privacy to certain boundaries hence limiting the use thereof only to those who have access to that particular area. The technology could also prove to be useful in hospitals because it does not create interference with medical materials.
The technology has also been tested in Belgium, Estonia and India.
