面向6G的可见光通信

 

 

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。

Abstract: 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, methods, special scene applications, heterogeneous networking and high-speed optical interconnection is discussed, as well as the challenges and the prospects.
