摘　　要：传统地铁隧道4/5G通信覆盖采用隧道壁挂泄漏同轴电缆的方式,但是该方案造价高且周期长,存在一定的局限性。为此,文章以福州地铁4号线螺洲温泉站至帝封江站为例,结合地铁隧道环境和天线无线传播模型的特点,提出采用窄波束贴壁天线替代泄漏同轴电缆的解决方案,对天线覆盖隧道方案的网络性能和实施安全进行研究,通过实践方案验证,该方案具有良好的经济性和安全性,相关研究成果可为其他隧道类场景4/5G通信覆盖提供参考。The traditional subway tunnel 4/5G communication coverage adopts the method of tunnel wall mounted leakage coaxial cables,but this scheme is expensive and has a long cycle,which has certain limitations.Therefore,this article takes the example of the Fuzhou Metro Line 4 from Luozhou Wenquan Station to Difengjiang Station,and combines the characteristics of the subway tunnel environment and antenna wireless propagation model to propose a solution of u-sing narrow beam wall mounted antennas to replace leaky coaxial cables.The network perform-ance and implementation sccurity of the antenna coverage tunnel scheme are studied,and through practical verification,the scheme has good economic and security,The relevant research results can provide reference for 4/5G communication coverage in other tunnel scenarios.
