Research on Improving 5G Network Coverage in High Speed Rail Tunnels
With the continuous construction of high-speed railways in our country,high-speed railways lead to various corners of the land of China,forming an interconnected high-speed rail-way network.China's terrain is complex,and high-speed rail inevitably has a large number of tunnel mileage.In order to meet the communication network needs of people's daily travel,do-mestic telecommunications operators have carried out 5G network coverage construction in the tunnels.Due to the operational characteristics of high-speed trains,the characteristics of high-speed train bodies,and safety requirements in tunnels,the coverage of 5G networks in tunnels cannot meet the coverage requirements;At the same time,the concentration of high-end mobile users on high-speed rail and frequent occurrence of data services are key scenarios that 5G net-works need to cover.This article analyzes the problems of high-speed rail coverage and,while ensuring the safety of high-speed rail tunnel operation,through a series of supplementary expan-sions,strives to improve the signal coverage of 5G networks as much as possible to meet network coverage requirements.
