摘要
相比城区网络覆盖,高铁网络覆盖则更具复杂性,成为线覆盖的重点和难点。文章通过对高铁覆盖的穿透损耗、多普勒效应及其影响因素分析,进而从站址选择、设备选型及天馈部署等方面进行覆盖策略研究,确立了公网与专网建设的原则,最后以南广高铁LTE网络部署为例进行覆盖分析及工程测试验证,为后期高铁网络部署提供了有益的参考。
Compared to urban network coverage,high-speed railway network coverage is more complex,become the focus and difficulty of line coverage.By analyzing factors of penetration loss,Doppler effect and its influencing factors,first of all,put forward coverage strategy of site selection,equipment selection and antenna deployment and other aspects.And then,construction principles of public network and private network.Finally, analysis and verify LTE network deployment of Nan Guang high-speed railway, which provides a useful reference for high-speed railway network deployment.
