摘　　要：5G Wi-Fi在使用过程中,会和雷达波的通信频段重合,对军用、气象雷达等各种必需的雷达信号会产生不必要的干扰,为此我们引入了DFS动态频率选择这一机制,让5G Wi-Fi和雷达波信号互不干扰。本文根据ETSI EN 3018935G RLAN标准无线局域网(RLAN)设备相关要求,介绍5G Wi-Fi DFS测试指标要求、测试过程和注意事项。During the use of 5G Wi-Fi,it will overlap with the communication frequency band of the radar wave,which will cause unnecessary interference to various necessary radar signals such as military radar and weather radar.Therefore,we introduce the DFS dynamic frequency selection mechanism so that 5G Wi-Fi and radar signals are not interfering with each other.According to the relevant requirements of ETSI EN 3018935G RLAN standard wireless local area network(RLAN)equipment,this article introduces the 5G Wi-Fi DFS test index requirements,test process and precautions.
