摘　　要：《关于加强和规范2400 MHz、5100 MHz和5800 MHz频段无线电管理有关事宜的通知》中增加了对无线电发射设备需具备干扰规避技术的要求,这对相关无线电产品的认证提出了新的要求。文章通过对当前802.11协议、主流Wi-Fi应用方案的基于帧和基于负载的2种干扰避让技术的分析,结合EN 300328标准中关于产品自适应测试的方法,搭建出满足干扰避让技术要求的测试方案,从而实现对无线电发射设备的干扰避让技术的验证,并针对测试未通过的情况给出了原因分析和解决问题的方向。Based on the“Notice on strengthening and standardizing the radio management of 2400 MHz,5100 MHz and 5800 MHz band”,the need for radio transmission equipment to have interference avoidance technical requirements has been added,which puts forward new requirements for the certification of related radio products.Through the analysis of the frame-based and load-based interference avoidance technologies of the current 802.11 protocol and mainstream Wi-Fi application solutions,combined with the method of product adaptive testing in the EN 300328 standard,a test scheme that meets the interference avoidance technology in the Notice is built.So as to realize the verification of the interference avoidance technology of the radio transmission equipment,and give the reason analysis and the direction to solve the problem for failed cases.
