5G试验网的频率干扰分析

Frequency Interference Analysis of 5G Test Network

产生无线干扰的原因是多种多样的,如不同运营商的网络配置不合理、发射机的数据设置、周围环境、小区重叠及电磁兼容等。当前全球多个国家已竞相展开5G网络技术开发,我国工业和信息化部于2018年12月正式发文,向中国电信、中国移动和中国联通三家运营商发放了5G系统中低频段试验频率的使用许可。5G试验网建设应该充分考虑不同制式通信系统之间的天线隔离度和干扰协调,本文将针对5G试验网的频率干扰进行分析。

There are many reasons for wireless interference,such as unreasonable network configuration of different operators,data setting of transmitters,surrounding environment,cell overlap and electromagnetic compatibility. At present,many countries around the world have launched the development of 5 G network technology. In December 2018,the Ministry of Industry and Information Technology officially issued a paper to China Telecom,China Mobile and China Unicom to license the use of low-frequency test frequency in 5 G system. The antenna isolation and interference coordination between different communication systems should be fully considered in the construction of 5 G test network. The frequency interference of 5 G test network is analyzed in this paper.
