基于地理位置变化的5G小基站传播特性研究

移动互联网和物联网时代来临,高数据业务需求推动着5G网络的致密化建设,加速部署小基站更适应5G网络的建设需求。有效地提供5G网络规划需要准确了解3.5 GHz传播特性,在半径为0.5 km的微蜂窝环境中,通过实测模拟信号与三维射线跟踪模拟结果的比较分析传播特性,推导出反映位置特性的最佳5G小基站传播模型。

Propagation Characterization Based on Geographic Location Variation for 5G Small Cells

With the advent of the era of mobile Internet and Internet of Things,the high demand of data service promotes the densification construction of 5G network,and accelerating the deployment of small cells is more suitable for the construction of 5G network.To effectively provide 5G network planning,it is necessary to accurately understand the 3.5 GHz propagation characteristics.This paper presents results of the analysis of radio propagation characteristics based on changes due to variation in location were measured using a channel sounder in a microcellular environment with a 0.5 km radius,a comparison between actual measurements and three-dimensional ray-tracing simulation results confirmed the validity of the best 5G small base station propagation model.
