Wireless Li-fi technology is tested, 100 times faster than wi-fi

Data transmission technology has already begun to be tested in some industrial offices.

Li-fi - Data transmission technology by light

About a half-year ago, scientists introduced a new theory of data transmission through visible light waves to replace today's wireless Wi-Fi technologies. The new technology is named Li-fi, which aims to create a new wireless connection standard that delivers superior transmission speeds.

Scientists have fabricated and tested the new Li-fi data transfer technology in the lab and measured extremely high data rates of up to 224 Gigabits per second, 28 gigabytes of data are transferred from one place to another in 1 second.

Most recently, the scientists first brought the technology from the lab and applied it in an office in Tallinn, Estonia, and recorded data transfer rates through Li-fi falls to 1 Gigabyte per second. That's about 100 times faster than today's average Wi-Fi.

Li-fi technology was first invented by Harald Haas , from the University of Edinburgh, Scotland in 2011, the idea came when he was demonstrating the ability to turn off the continuous light of a single LED and Harald Haas Noticeably, this method of transmitting information can travel further than conventional broadcast towers. And the idea arises from that.

Li-fi uses visible light transmission (VLC) technology to transmit light signals in the 400 to 800 range of TeraHertz, which acts as an improved version of the Morse code, The binary codes are transmitted in the form of light by sending two states of light on and turning off the lights to the destination, the two off states will be equivalent to the two numbers 0 and 1 of the binary.

The state of the LEDs being switched on at high speed generates a binary string carrying information that is sent to the receiver. That's how the Li-fi network works.
