Data transmission technology Li-Fi shows speed in 100 times more than the average Wi-Fi

In the near future, expect the talk about Li-Fi — wireless technology that transmits data at a high speed using the communication channel of the visible light (visible light communication or VLC). Since the researchers achieved data transmission speeds to 224 gigabits per second, the potential of this technology promises to change all that, as usual we use the Internet.



Now, researchers first brought the technology Li-Fi research lab, testing it in the office and industrial environment in Estonia Tallinn, saying that can reach speeds of 1 Gigabit per second — 100 times faster than average Wi-Fi speed.

"We are doing several pilot projects within different industries can use the technology of communication via visible light", says head of Estonian technology companies Velmenni Deepak Solanki.

The technology Li-Fi was invented by Harald Haas from the Scottish University of Edinburgh in Scotland in 2011, when he first demonstrated that with the help of the flickering light from a single led can transmit much more data than a cellular tower. And if to take into account the laboratory values of speed of 224 gigabits per second, this is equal to downloading about 18 movies with a volume of 1.5 GB per second.

The advantages of Li-Fi over Wi-Fi in addition to the potentially high speeds that the light does not pass through walls, and it makes the process of data transmission much more secure, and also means less interference between devices. published
