#light transmission

The entity behind the Wi-Fi 802.11 standards—Institute of Electrical and Electronics Engineers (IEEE)—has released the 802.11bb as its latest global light-based communications standard. Li-Fi is a wireless technology that uses light, instead of radio frequencies, to transmit data. How it works By utilizing the light spectrum, Li-Fi can provide ‘faster’ and ‘more reliable’ wireless connectivity that is more secure than conventional technologies like WiFi and 5G. As of June 2023, the IEEE 802.11 recognizes wireless light communications (LC) as a physical layer for wireless local area networks. https://youtu.be/kDqA1-ldTOI The Fraunhofer HHI video demonstrates a Li-Fi system that utilizes a building's lighting infrastructure for data transmission. One, is that its sensitivity to lighting conditions can vary significantly, and it is easy to accidentally cut off a line-of-sight connection. Another disadvantage is its limited range, as the light is stationary and confined to a specific line of sight. One of the major players in the Li-Fi industry, pureLiFi, has already developed the Light Antenna ONE module, which is 14.5mm component for LC and is currently being offered to OEMs for evaluation.
