摘 要:5G作为支撑经济社会数字化转型的关键新型基础设施,成为加速我国数字化转型进程、助力经济高质量发展的重要引擎。700 MHz是我国5G发展过程中非常重要的一段频率资源,该频段具有信号准确、覆盖面广泛、穿透力强等特点。针对700 MHz无线频段覆盖能力的研究是5G网络规划和优化的重要工作,文章对5G常用频段的无线信号传播损耗与传输距离、中心频率、穿透媒介材质、地形和建筑物阻挡等各种因素的量化关系进行了理论分析,并通过仿真,对5G常用频段在典型应用场景下的覆盖能力进行分析,为5G无线网络规划提供参考。As a key new infrastructure supporting the digital transformation of the economy and society,5G has become an important engine for accelerating the process of digital transformation in my country and helping the high-quality development of the economy.700 MHz frequency band is a very important resource in the development process of 5G today.The frequency band has the characteristics of accurate signals,wide coverage,and strong penetration.Therefore,the analysis of 700 MHz wireless frequency band coverage will become an important development direction.This paper gives a theoretical analysis of the relationship between the propagation loss and path of 5G commonly used frequency bands,the effect of different frequencies and materials on penetration loss,and the effect of different frequencies on diffraction loss.And further,the simulation results of coverage capabilities of 5G common frequency bands in typical scenarios provide a reference for 5G wireless network planning.
