摘　　要：伴随着5G网络建设的不断深入,5G行业应用的范围不断拓展,海洋渔业、离岸岛屿、近海旅游、海上边防和草原作业等特殊场景对于5G网络的覆盖需求也越来越迫切。其中对于近海海面等场景,需要依托通信网络的超远覆盖能力以实现海域的5G网络全覆盖。本文分析了无线通信系统超远覆盖能力的影响因素,阐述了5G超远覆盖关键技术,并搭建了相关技术参数设置模型。最后基于网络测试,验证了基于700 MHz的5G网络超远覆盖能力,充分证明了5G超远覆盖的应用潜力。With the continuous deepening of 5G network construction,the scope of 5G industry applications continues to expand.Special scenarios such as marine fishery,offshore islands and offshore tourism,maritime border defense,and grassland operations are becoming more and more urgent for 5G network coverage.Among them,scenarios such as near sea and sea surface need to rely on the ultra-long range coverage capability of the communication network to achieve full coverage of the 5G network in the sea.This paper analyzes the infl uencing factors of the ultra-long range coverage of wireless communication systems,analyzes and elaborates the key technologies of 5G ultra-long range coverage,and builds a model for setting related technical parameters.Finally,based on the live network test,it verifi es the ultra-long range coverage of the 5G network based on 700 MHz,Which fully proved the application potential of 5G ultra-long range coverage.
