Research on Coverage and Optimization of Wireless Communication Network in Subway Scene
With the rapid development of urban transportation,subway is an important part of public transportation,and its wireless communication network coverage and optimization is particularly important.This paper deeply analyzes the present situation of wireless communication network in subway scene,and points out the challenges faced by wireless communication network in high-speed mobility,multipath effect,signal attenuation,car penetration loss and human occlusion effect.At the same time,the traditional and new subway wireless communication network coverage technologies,including leaky wave antenna,repeater,5G small base station and Distribution Automation System(DAS),are discussed,and their performances are compared and their applicability is analyzed.Finally,the optimization methods of subway wireless communication network are put forward,such as signal enhancement technology and spectrum optimization based on smart antenna array,network parameter adjustment algorithm based on machine learning,user behavior prediction and dynamic resource allocation,multi-network integration technology and vertical switching mechanism.This study aims to provide theoretical guidance and technical reference for the coverage and optimization of subway wireless communication network.
