老實說我不太懂你的意思 你引維基百科是要說WIFI6E包含2.4G/5G? 說真的我不太喜歡引維基上的資料,因為不是官方的資料 管WIFI最大的的叫wifi alliance 我們來看看WIFI 6E 認證要認證什麼 https://www.wi-fi.org/discover-wi-fi/wi-fi-certified-6 "Wi-Fi 6E extends Wi-Fi CERTIFIED 6 into 6 GHz Wi-Fi operation in the 6 GHz frequency band enables Wi-Fi to continue delivering positive experiences for the most bandwidth intensive applications. Wi-Fi 6E certification as part of Wi-Fi CERTIFIED 6 offers the features and capabilities of Wi-Fi 6, extended to the 6 GHz band. Several nations around the globe are making the 6 GHz band available for unlicensed use, and Wi-Fi CERTIFIED 6 provides worldwide interoperability certification for devices in these markets." WIFI6E認證就是6Ghz的頻段驗證 所以你要認證WIFI6E當然就是一定要有6G 雖然不是說一定要認證才能說自己是WIFI6E router 不過我想沒有廠商會在沒有支援6G頻段的情況下會宣稱自己的產品是WIFI6E AP router 就算是油條如小米,他也只敢打擦邊球 https://www.mi.com/r6000 只敢寫wifi6加強版,絕對不敢寫WIFI6E 順便講一句維基那張圖錯了 802.11AX的確是包含2.4G/5G/6G 但是WIFI6E絕對不包含5G/2.4G 802.11AX是WIFI6+WIFI6E的集合
