French startup showed light link: LiFi is 100 times faster than WiFi

At the last mobile fair Mobile World Congress in Barcelona, ​​French start-up Oledcomm demonstrated the capabilities of Li-Fi technology - wireless transmission of information using light. The developers claim that the speed of Li-Fi is 100 times higher than the speed available using Wi-Fi devices.



The developers also said that in the laboratory, the maximum transfer rate was 200 Gbps - as the founder and head of Oledcomm, Suat Topsu, put it, “23 DVDs per second.”

A company representative explained that LEDs are used to transmit information, which quickly flash and encode data in this way. According to Topps, this system is the “digital equivalent of Morse code”.



The technology left the laboratories in 2015 and passed testing stages in various public places, including museums and shopping centers. It is reported that Philips is interested in technology (Philips is producing a line of “smart” LED bulbs and Hue controllers ), and Apple may even use it in the new iPhone 7.



The creators of the technology claim that Li-Fi will help replace Wi-Fi due to its limitations on the number of simultaneously connected devices and the lack of radio frequencies.



The advantage of Li-Fi is the ability to transmit data on a directional beam, which eliminates the possibility of interception. Disadvantages are the need for a direct view of the transmitter and the inability to transmit data through obstacles, such as walls.
