5G基站电磁辐射环境特征及监测实证研究

Empirical Research on Monitoring and Characteristics of Electromagnetic Radiation Environment of 5G Base Stations

根据5G基站工作原理及发射特点,研究了5G基站的电磁辐射方向、强度与用户终端位置分布及应用场景存在的对应关系。经实测验证,终端位置移动将导致电磁辐射方向发生显著变化;多终端窄波辐射相互叠加与应用场景明显相关,基站小区辐射覆盖范围扩大。建议对现行移动通信基站电磁辐射环境监测技术方法进行研究修订。

According to the working principle and transmitting characteristics of 5G base station,the relations between the direction and intensity of electromagnetic radiation,the location distribution of user terminal and the application scenario of 5G base stations were studied.The practical measurement results showed that the moving of terminal position resulted in significant change in radiation direction.The superposition of multi-terminal narrow-wave radiation had significant correlation with application scenarios.The radiation coverage of the base cell was expanded.It was suggested to revise the current method of electromagnetic radiation environmental monitoring for mobile communication base station.
