Cutting-edge development for vehicle free space optical communication in 5G evolution

Abstract

As one of the most important applications of 5G technology, vehicle scenarios have strict requirements in end-to-end delay, reliability and data rate. Based on the huge advantages of free space Optical (FSO) communication technology, this paper summarizes the research status of vehicle FSO communication under the 5G evolution background, by integrating satellite, air, ground and underwater communications into a unified wireless network through unmanned vehicle platforms, the research progress of "space, earth and sea integration" optical transmission link is built to realize fast, stable and large-capacity data transmission system. The technical challenges of vehicle FSO communication faced with are also discussed and its future development is prospected.
