Wi-fi 6應該帶來什麼改進?

在詢問了通信行業的專家之後，我簡要總結了Wihkbn 5g-Fi6應該帶來的好處：

首先，速度有了提高。 由於Wi-Fi 6採用1024-QAM調製和編碼方案，與之前的256-QAM相比，它有了很大的改進，無線網路的最大連接速率提高到9.6Gbps，即1.2GB/S，這是千兆寬頻的全速。 換句話說，除了啟用Wi-Fi 6的設備外，以前的設備都無法達到這種全速狀態。

其次，Wi-Fi6的優點也體現在高密度接入上，比以往的OFDMA技術(正交頻分多址)效率更高。為了方便你的理解，我認為這個改進可以這樣解釋：OFDM模型就像a，B，C，每個人都有一個特殊的汽車攜帶貨物從E城市F城市，因為它是一個特殊的車，所以，每個運輸，不是等待貨物滿，隨時航運只要貨物可用，大量的資源浪費;雖然OFDMA是不同的，A、B，C三個人可以分享一輛車，試著填補三個人和一輛車，開始航運，然而，同時出發的數量仍然不變，仍然之前的三輛車，所以，每次有更多的貨物交付，運輸效率已經大大提高。

最後，Wi-Fi 6的改進還在於對MU-MIMO技術(多用戶多輸入多輸出)的支持。 也許一些熟悉的朋友會說，以前的Wi-Fi 5也支持MU-MIMO技術，是的，但Wi-Fi 5支持的MU-MIMO技術只用於下行鏈路，此外，Wi-Fi 6的不同之處在於它可以同時支持上下MU-MIMO技術，並且允許路由器與設備通信的次數增加到8次， 提升本身就說明問題。

簡單來說，在 wi-fi 5之前，如果資訊傳輸被比作一條道路，那就像一條只有一個收費亭 wi-fi 5的高速公路，就像把收費亭的數量增加到四個，其中三個仍然只允許單向行駛; wi-fi 6是一條雙向的八車道高速公路，讓車輛以最好的方式通過。當然，效率已經大大提高了。
