摘要
无线通信中的频段资源已经十分紧张,在6G复杂的通信环境下,传统的无线通信也难以达到全面的高速覆盖。可见光通信作为一种利用400~800 THz无须授权频段的高速通信技术,将在6G网络中担任重要的角色。从器件、速率、特殊场景应用、异构组网和高速光互联5个方面讨论了可见光通信的进展,并介绍了现阶段面临的挑战和对未来的展望。
Frequency band resources in wireless communication are already very tight,and it is difficult for traditional wireless communication to reach full high-speed coverage in 6G complex communication environment.Visible light communication(VLC),as a high-speed communication technique taking advantage of unlicensed spectrum of 400-800 THz,will take an important role in 6G.In this paper,the recent research in VLC including devices,rate,special scene applications,heterogeneous networking and high-speed optical interconnection is discussed,as well as the challenges and the prospects.
