Li-Fi delivers internet 100 times faster, could replace Wi-Fi in the future
- 8 years ago
TALLINN, ESTONIA — A new form of Internet data delivery is making its way to the market, and it might replace Wi-Fi in the coming years.
Li-Fi, or Light Fidelity, uses LED light bulbs to send information, and theoretically can deliver Internet access 100 times faster than Wi-Fi. LED light bulbs emit visible lights, which is a constant stream of photons. When the current is manipulated to create slight fluctuations, a photodetector device can pick up the pulses to convert them into an electrical current, said German physicist Harald Haas during a TED Talk.
Haas is a professor of mobile communications at the University of Edinburgh and the founder of pureLiFi, a leading company in Li-Fi technology.
An Estonian company, Velmenni, tested the technology and was able to transmit data at 1 gigabyte per second. Theoretically it can deliver speeds of up to 224 gigabytes per second.
However, because Li-Fi uses only visible light, it does not work through walls, nor will it work outdoors in the sunlight.
In the future, light bulbs could become wireless hotspots and could be utilised on aircraft and in other places where radio signal interference is an issue.
Due to its limitations, initial usage of the technology may be restricted to crowded urban areas, or in areas where Wi-Fi usage may not be safe, such as hospitals.
