The July 2023 report by LiFi.co offers an overview of LiFi, a technology first developed in 2011. LiFi (Light Fidelity) functions like Wi-Fi as a local network for data distribution and control, but instead of using radio bands for transmission, LiFi utilizes visible, infrared, and ultraviolet light. LiFi modulates the light emitted from a lamp at a high rate, making the changes invisible to humans. The benefits of LiFi include data speeds up to 224 gigabits per second (in lab tests), an uncongested spectrum that is 10,000 times larger than the radio spectrum, enhanced security as signals do not penetrate walls, safety, no interference, and efficiency, especially when using LED lamps. The report describes various applications and discusses limitations in bright outdoor environments and the development of receiving devices.
