Research and Practice of Narrow Beam Wall Mounted Antenna in Subway Tunnel Communication Coverage
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 security 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.
