The standardization of Li-Fi, or light-based Wi-Fi, has just been announced by the Institute of Electrical and Electronics Engineers (IEEE), signifying a potential future where we can connect to the internet using beams of light. This milestone was reported by Android Police, and companies pureLiFi and Fraunhofer HHI, leading the development of Li-Fi, have expressed their excitement in a joint press release.
However, it should be noted that the introduction of an official standard does not imply an immediate replacement of traditional Wi-Fi by Li-Fi. Instead, it is more likely that the two technologies will coexist and be utilized depending on the specific requirements of different situations. Nevertheless, significant Li-Fi capabilities on consumer devices may still be several years away. Nonetheless, pureLiFi has already developed a compact “light antenna” that could potentially be integrated into smartphones, suggesting an earlier arrival of Li-Fi than expected.

Unlike conventional Wi-Fi that utilizes radio waves for data transmission, Li-Fi achieves wireless data transfer through the flickering of light in a specific manner. This method allows Li-Fi receivers to interpret the light signals and transfer data accordingly. Furthermore, there is no need to worry about excessive flashing lights as current LED lights already switch on and off at rapid speeds, which are generally imperceptible to the human eye. Additionally, Li-Fi can function with visible, infrared, and ultraviolet light.
The establishment of an official standard signals a promising future for light-based connectivity.
