Li-Fi or Light Fidelity, could one day replace the conventional Wi-Fi after an Estonian startup showcased its Li-Fi technology in action, BBC reported on Friday.
The report says that Li-Fi or Light Fidelity can deliver 100 times faster Internet on smartphones and computers compared to a Wi-Fi connection, making the former far more superior compared to conventional Wi-Fi connections.
Estonian startup Velemeni has dubbed its Li-Fi technology as Jungru, which uses an LED bulb that transmits data at gigabits speeds. Theoretically, Li-Fi can offer a maximum speed of up to 200 gigabits per second while the fastest Wi-Fi speed ever recorded is close to 100 gigabits per second.
Though the use of Li-Fi Internet Technology will have its own set of limitations. The most obvious hindrance with the technology is light inability to pass through walls. Its biggest drawback however apart from walled spaces, is its inability to provide uninterrupted Internet data connections outdoors with visible light from the sun, as natural daylight would hinder with its signal.
Velemenni’s chief Deepak Solanki seems fairly confident that the Intenet Technology could reach the consumer market within the next 3 to 4 years, though they must create an infrastructure for Li-Fi that can work with the current system.
“It is very difficult to create a whole new infrastructure for Li-Fi so somehow we need integrate our system with the current system,” said Solanki.
To recall the terms, Li-Fi was first coined by Prof Harald from Edinburgh University in 2011 at a TED conference during which he showed a video.
The video added: “By flickering the light from a single LED, a change too quick for the human eye to detect, (Haas) can transmit far more data than a cellular tower, and do it in a way that’s more efficient, secure and widespread”.
Professor Haas also said that in the coming future, the world ” would not only have 14 billion light bulbs,” but also 14 billion Li-Fis deployed in all countries.
