1、6G Visible Light CommunicationTechnology White PaperChina Mobile Research InstitutePrefaceWith the increasingly stringent communication requirements,more spectrum isurgently needed for mobile communication.Since the spectrum resources below6GHz has been depleted,and the millimeter-wave frequency ban

2、ds such as 26GHzand 39GHz have been allocated for 5G use,it is necessary to explore higherfrequency bands for communication,such as terahertz communication and visiblelight communication(VLC),to meet the requirements of higher capacity andultra-high experience rate.Visible light usually refers to el

3、ectromagnetic waves of380790THz(wavelength ranges is 380790nm).The candidate spectrum coversabout 400THz.The characteristicsof large bandwidth andeasy torealizeultra-high-speed communication make VLC become a potential supplement to futuremobile communication systems.This white paper aims to discuss

4、 the potential application scenarios of VLC in 6Gand the communication requirements expected to be met,and proposes the challengesand key technologies of VLC,so as to promote the discussion and thinking in theindustry.The white paper is supported by the partner teams of Fudan University,BeijingUnive
