摘要
在无线通信领域中,仿真评估技术对指导网络规划建设至关重要。传统无线网络仿真采用的模型相对单一且较为理想,而实际无线信号在空间传播中一般会受到建筑物、树木等阻挡。通过Planet 5G系统仿真平台3D射线追踪模型,结合5 m高精度矢量地图,对规划的5G基站分别基于2.6 GHz和3.5 GHz两种频段进行仿真分析对比,得出了两种频段在网络建设中的覆盖差异,能够较好地评估5G无线网覆盖的真实情况,对运营商的实际部署具有一定的参考和实用价值。
In the field of wireless communication,simulation evaluation technology is very important to guide network planning and construction.The model used in traditional wireless network simulation is relatively single and ideal,while the actual wireless signals are generally blocked by buildings and trees in space propagation.Through the 3D ray tracing model of the Planet 5G system simulation platform,combined with the 5 m high-precision vector map,the planned 5G basestation is simulated and compared based on the 2.6GHz and 3.5GHz frequency bands and the coverage difference of the two frequency band in the network construction is obtained,which can better evaluate the real situation of 5G wireless network coverage and has a certain reference and practical value for the actual deployment of operators.
