6G可见光通信技术白皮书（英）

With the increasingly stringent communication requirements, more spectrum is urgently needed for mobile communication. Since the spectrum resources below 6GHz has been depleted, and the millimeter-wave frequency bands such as 26GHz and 39GHz have been allocated for 5G use, it is necessary to explore higher frequency bands for communication, such as terahertz communication and visible light communication (VLC), to meet the requirements of higher capacity and ultra-high experience rate. Visible light usually refers to electromagnetic waves of 380~790THz (wavelength ranges is 380~790nm). The candidate spectrum covers about 400THz. The characteristics of large bandwidth and easy to realize ultra-high-speed communication make VLC become a potential supplement to future mobile communication systems.

This white paper aims to discuss the potential application scenarios of VLC in 6G and the communication requirements expected to be met, and proposes the challenges and key technologies of VLC, so as to promote the discussion and thinking in the industry.
