Linux will support new network technology based on Li-Fi

According to phoronix, Li-Fi technology supplier PureLiFi has recently been actively contributing code to the Linux kernel community to promote the incorporation of its open source Li-Fi driver into the Linux kernel mainline.

Li-Fi stands for Light Fidelity, and its Chinese name is "Light Fidelity Technology". It is a new wireless transmission technology that uses the visible light spectrum for data transmission. It was invented by Professor Harald Hass, Chairman of the Department of Mobile Communications at the School of Electronic Communications at the University of Edinburgh, UK, and a German physicist.

The technical principle of Li-Fi is to use fast light pulses to transmit information wirelessly. A simple example is that the LED light turns on to represent 1 and turns off to represent 0, and encoding can be achieved through rapid switching. In practical applications, Li-Fi usually uses electrical signals to control LEDs to emit high-speed flashing signals that are invisible to the naked eye to transmit information. Li-Fi has the same advantages as fiber optic communication, high bandwidth and high speed. The difference is that Li-Fi allows light to propagate in the environment around us. Wherever natural light can reach, there is a Li-Fi signal. The deployment of Li-Fi technology can use the ubiquitous light bulbs in life. As long as a tiny chip is implanted in the light bulb, it can be turned into a device similar to a Wi-Fi hotspot, allowing the terminal to access the network at any time.

PureLiFi is a company dedicated to promoting Li-Fi technology and developing and manufacturing Li-Fi equipment. It was founded by Professor Harald Hass, the inventor of Li-Fi technology. At present, Li-Fi network technology is in a relatively early stage. PureLiFi's equipment supports the Li-Fi dedicated standard of the Institute of Electronic Engineers IEEE 802.11.bb, which is scheduled to be fully approved in early 2021. Market research firm Global Market Insights predicts that by 2023, the global Li-Fi market will reach US$75 billion.

In recent months, PureLiFi engineers have been working hard to contribute their open source drivers to the Linux kernel community to enable their LiFi-X, LiFi-XC and LiFi-XL USB devices to work under Linux systems.

It is reported that the driver submitted by PureLiFi engineers has been accepted by the Linux network subsystem maintainers and has undergone several optimization changes. The code has not yet entered Linux's net-next, but it is likely to be adopted by the Linux kernel in the next one or two kernel cycles.
