摘　　要：Wi-Fi 7(802.11be)是最新一代的Wi-Fi标准,对Wi-Fi 6(802.11ax)进行了多项技术改进,包括MLO多链路操作技术、前导码打孔技术、MRU多资源单元、4096 QAM调制、320 MHz带宽和更大的空间流。这些技术提升了传输速度、降低了延迟、提高了连接稳定性和能效。为了评估这些新技术的性能,国内外测试标准也进行了更新,包括国内SRRC的MLO测试、MRU测试和EVM测试,以及欧盟CE的带外发射测试、信道访问机制测试和接收选择性测试。这些测试方法主要通过频谱分析仪、无线网络测试仪以及综测仪等设备来实现,以确保Wi-Fi 7设备的性能符合标准要求。Wi-Fi 7 (802.11be) is the latest generation Wi-Fi standard,which has made multiple technical improvements to Wi-Fi 6 (802.11ax),including MLO multilink operation technology,preamble punching technology,MRU multi resource unit,4096 QAM modulation,320 MHz bandwidth,and larger spatial streams.These technologies have improved transmission speed,reduced latency,enhanced connection stability,and energy efficiency.In order to evaluate the performance of these new technologies,domestic and international testing standards have also been updated,including MLO testing,MRU testing,and EVM testing for domestic SRRC,as well as out of band transmission testing,channel access mechanism testing,and reception selectivity testing for EU CE.These testing methods are mainly implemented through equipment such as spectrometers,wireless network testers,and comprehensive testers to ensure that the performance of Wi-Fi 7 devices meets standard requirements.
