So, what is WiFi 7?
那麼，WiFi 7 是什麼？

WiFi 7 is the upcoming Wi-Fi standard set by the Institute of Electrical and Electronics Engineers (IEEE). It will work across all three wireless bands (2.4 GHz, 5 GHz, and 6 GHz) and will be differentiated from its previous WiFi 6 predecessor by making a performance gain for consumers by having extreme speed and low latency. What that means to you is that you can take advantage of 8k video streaming, experience Virtual Reality (VR) or extended reality (XR), and utilize multi and simultaneous video conferencing. The use cases for consumers and businesses will explode as we explore what else we can do with our devices with WiFi 7.
WiFi 7 是由電機電子工程師學會（IEEE）設定的即將推出的 Wi-Fi 標準。它將在所有三個無線頻段（2.4 GHz、5 GHz 和 6 GHz）上運作，並通過極速和低延遲為消費者帶來性能提升，與其前身 WiFi 6 有所區別。對您來說，這意味著您可以利用 8k 視頻串流，體驗虛擬現實（VR）或擴展現實（XR），並利用多路和同時視頻會議。隨著我們探索使用 WiFi 7 在設備上可以做什麼，消費者和企業的應用案例將會激增。

4kQAM

WiFi 7 will enable faster speeds by standardizing an advanced modulation schema called 4k QAM (Quadrature Amplitude Modulation), which empowers each signal to carry 12 bits instead of 10 bits (20% increase). 4k QAM will pack more data in each signal, which will help increase throughput and capacity compared to WiFi systems using 1k QAM.
WiFi 7 將通過標準化一種名為 4k QAM（正交振幅調製）的先進調製方案，實現更快的速度，該方案使每個信號能夠攜帶 12 位而不是 10 位（增加 20%）。 4k QAM 將在每個信號中打包更多數據，這將有助於提高吞吐量和容量，與使用 1k QAM 的 WiFi 系統相比。

WiFi 7 Channels WiFi 7 頻道

Each channel on WiFi 7 will be 320 MHz, double the previous WiFi generations. In short, the new modulation will allow for greatly denser data packets to travel on wider channels. That means a WiFi 7 device will have a potential maximum data rate speed double that of any WiFi6/6E device. You’ll be able to watch 4k and 8k videos, play online games without lag, download large files in seconds, and much more.
每個 WiFi 7 上的頻道將為 320 MHz，是之前 WiFi 世代的兩倍。簡而言之，新的調製將允許更密集的數據包在更寬的頻道上傳輸。這意味著 WiFi 7 裝置將具有潛在的最大數據速率速度，是任何 WiFi6/6E 裝置的兩倍。您將能夠觀看 4k 和 8k 視頻，無延遲地玩線上遊戲，幾秒鐘內下載大文件，以及更多。

Multi-link Operation and Latency
多連結操作和延遲

Today’s Wi-Fi devices provide access to multiple wireless bands, discussed earlier, but typically only use a single link to transmit data, only switching to another if conditions change. Wi-Fi 7 will introduce multi-link operation (MLO) options that allow devices to connect simultaneously on two bands, leading to increased throughput, reduced latency, and increased reliability. This means that your data will now have more bands to travel on and create quicker connections even in congested areas or share the same redundant data to ensure that it arrives in case the other fails. MLO is excellent for emerging technologies like cloud computing, online gaming, VR/AR, and video streaming.
今天的 Wi-Fi 裝置提供存取多個無線頻段，但通常只使用單一連結來傳輸數據，只有在條件改變時才切換到另一個。Wi-Fi 7 將引入多連結操作（MLO）選項，允許裝置同時在兩個頻段上連接，從而提高吞吐量、降低延遲並提高可靠性。這意味著您的數據現在將有更多頻段可供傳輸，即使在擁擠的區域也能建立更快的連接，或共享相同的冗餘數據以確保在另一個失敗的情況下到達。MLO 對於新興技術如雲端運算、線上遊戲、虛擬現實/擴增實境和視訊串流非常有用。

Multi-RU 多 RU

With legacy Wi-Fi, each user can only send or receive data on an assigned resource unit (RU), meaning that if another user uses any part of a large high-speed channel, the entire channel is unavailable. This leads to significant limits on the flexibility of the spectrum resource scheduling. With multi-RU puncturing, Wi-Fi 7 devices will be allowed to use other parts of the same high-speed channel that are not in use, allowing single users to combine RUs to increase transmission efficiency. This flexibility will help alleviate congested networks and bands and enable users to take advantage of all the resources available in the network.
使用傳統的 Wi-Fi，每個用戶只能在分配的資源單元（RU）上發送或接收數據，這意味著如果另一個用戶使用大型高速通道的任何部分，整個通道將不可用。這導致對頻譜資源調度的靈活性存在顯著限制。通過多 RU 打洞，Wi-Fi 7 設備將被允許使用未被使用的同一高速通道的其他部分，從而使單個用戶可以結合 RU 以提高傳輸效率。這種靈活性將有助於緩解擁擠的網絡和頻段，並使用戶能夠利用網絡中所有可用的資源。
