6GHz^100GHz频段传播特性及覆盖能力分析

Study on 6GHz ~ 100GHz band propagation characteristics and coverage analysis

为了分析6GHz^100GHz应用于移动通信的覆盖能力,文中首先分析了大气和雨水分别对该频段无线电波传播的影响。基于自由空间传播模型,叠加气衰和雨衰,构建出不同路损因子下的传播模型。最后依据链路预算理论,仿真实现不同频率在不同路损因子下的可达传播距离与传播速率的映射关系。理论仿真结果显示,在一定条件下,6GHz以上频段在覆盖范围从几十到几百米范围内达到了可接受的传播速率。

In order to analyze the coverage performance in the spectrum between 6GHz and 100 GHz applied to mobile communications,first of all,this paper analyzes the effects of the atmospheric gasesand rain attenuation in this spectrum,respectively. Based on the free space propagation model super posing atmospheric gases attenuation and rain attenuation,the propagation model with different path loss exponent is constructed. Finally,according to the link budget theory,the mapping between the coverage distances and data transmission rates with different frequencies in different path loss exponentsis obtained by the simulation. The theoretical evaluation results show that the spectrum above 6GHz can,to some extent,achieve acceptable data rates for the coverage of tens to hundreds meters.
