摘要
对立体仿真实现流程进行介绍,并以某典型城区为案例进行仿真评估,通过对比平面与立体仿真的RSRP及SINR指标,得出立体仿真能够更加真实地反映高层和低层的信号覆盖,比平面仿真更具合理性;为更好地分析不同高度的覆盖情况,结合指标分布情况来划分高、中、低层场景,分析不同分层场景下的覆盖问题,在此基础上提出异构组网规划思路及设计策略,为4G网络规划提供技术参考。
It introduces the procedure of 3D simulation,and take dense urban area as an example to validate simulation. Through coverage evaluation of 2D and 3D RSRP and SINR index,3D simulation index is found to be reasonable than 2D,it can reflect coverage of upper and lower layer. In order to analyze coverage of different layers in detail,upper layer,middle layer and lower layer are divided according to index distribution circumstance,and the coverage circumstance of different layers is obtained in further research,so that the targeted network planning which can offer technical reference for 4G network planning is gained.
