图一. Wi-Fi 6E Channel 由于6GHz的使用带宽有1200MHz,而在20MHz的Channel就有59个之多,若要将每一个Channel都扫到的话,势必会花费较多的时间才能与AP建立联机。为了减少扫描Channel的时间Wi-Fi 6E增加了Preferred Scanning Channels (PSC)方式解决,其功能会优先去找寻15个PSC,分别为:5, 21, 37, 53, 69, ...
Wi-Fi 6E Channelization The 802.11ax standard also defines channel allocations for the 6 GHz band. This allocation determines the center frequencies for 20 MHz, 40 MHz, 80 MHz and 160 MHz channels. Channels begin at the start frequency of 5950 MHz, leaving just 25 MHz of guard band between...
Wi-Fi 6E. The 6 GHz band is the next frontier in Wi-Fi. Supporting up to seven 160 MHz channels, Wi-Fi 6E delivers the fastest Wi-Fi yet addressing high bandwidth, low latency use cases while enabling multi-gigabit connectivity.
160 MHz Channel Width OFDMA, 8x8 MU-MIMO Extended to the Latest 6 GHz Band Congestion-Free, Less Interference, and Lower Latency 7x 160 MHz Channels for More Spectrum* *The FCC opened up 1200 MHz (7× 160 MHz) of spectrum in the 6 GHz band, paving the way for Wi-Fi 6E in the US...

Wi-Fi 6E在6GHz频段的信道划分如下: 图4. Wi-Fi 6E在6GHz频段的Channel Allocation 从上图可知,6GHz频段的频谱可带来59个20MHz信道、29个40MHz信道、14个80MHz信道和7个160MHz信道,拓展频谱将2.4GHz和5GHz的总容量提高了近六倍,将能够支持需要更快数据吞吐量以及低延迟连接的高带宽应用程序,特别适合下一代用...
The implications of WiFi 6E’s additional spectrum on the 6GHz band are a really, really big deal. For your router to deliver the best possible performance, it needs to create 160MHz-wide channels using 20MHz blocks. The 5GHz band is just large enough to accommodate three o...
基于5GHz Wi-Fi 6支持的理论速率在9.6Gbs,但这是在无线环境非常理想的情况下才有可能出现的结果。实际部署场景中,通常是多台Wi-Fi设备连接一个热点,以及多个热点在同一地点共存,设备和热点间的co-channel或者adjacent channel干扰不可避免。 Wi-Fi采用的载波侦听多路访问(CSMA)技术,既设备需要在确定频段没有被占有...
Wi-Fi 6E uses 6GHz spectrum to improve speeds over Wi-Fi 6 by reducing congestion with multiple new 160MHz channels.
