Wi-Fi 7 是最新一代的無線網絡標準（官方名稱為 IEEE 802.11be）

Wi-Fi 7 是最新一代的無線網絡標準（官方名稱為 IEEE 802.11be），也被稱為「極高吞吐量」（EHT, Extremely High Throughput）網絡。它的核心目標是全面提升傳輸速度、將延遲值降到最低，並大幅提高網絡的穩定性，是目前追求極致網絡體驗的最新標準。

🚀 Wi-Fi 7 的三大核心優勢

極致速度：理論最高速度高達 46 Gbps，比 Wi-Fi 6（9.6 Gbps）快了約 4.8 倍。

超低延遲：大幅減少遊戲、視訊會議及 AR/VR 設備的畫面延遲與卡頓。

超大容量：即使全屋同時連接數十台智能家居設備，網絡依然能保持流暢不擁堵。

🛠 帶來改變的關鍵新技術

Wi-Fi 7 之所以能迎來飛躍性的提升，主要是引入了以下幾項革命性技術：

320 MHz 超寬頻道：開放了全新的 6 GHz 頻段，並將頻道頻寬從上一代的 160 MHz 倍增至 320 MHz，如同將原本的行車馬路拓寬一倍，讓數據傳輸量翻倍。

MLO 多頻聚合連線（Multi-Link Operation）：過去的 Wi-Fi 設備一次只能連接一個頻段（2.4 GHz 或 5 GHz）。Wi-Fi 7 允許設備同時連接多個頻段（如同時連 5 GHz + 6 GHz）進行數據傳輸，不僅疊加了速度，還能在其中一個頻段受干擾時無縫切換，網絡極其穩定。

4K-QAM 高階調制：從 Wi-Fi 6 的 1024-QAM 升級至 4096-QAM，能夠在相同的無線訊號中，多打包 20% 的數據資料，讓傳輸更密集、更快速。

Multi-RU 與前導碼刪除（Preamble Puncturing）：過去若頻道中某個部分受到干擾，整個頻道都會被浪費。新技術允許網絡繞過受干擾的訊號片段，繼續使用其餘乾淨的頻寬，大幅提升抗干擾能力。

💡 升級前你需要注意甚麼？

雖然 Wi-Fi 7 技術非常強大，但要完全發揮它的實力，需要滿足以下條件：

設備端需支援：除了購買 TP-Link 或 NETGEAR 等品牌的 Wi-Fi 7 路由器外，你的手機（如新款旗艦機）、筆記型電腦也必須內置支援 Wi-Fi 7 的無線網卡。

寬頻網速搭配：如果家中的家居寬頻只有 100M 或 1000M（1G），升級 Wi-Fi 7 的視覺體感可能不明顯。Wi-Fi 7 路由器通常配備 2.5G 甚至 10G 的有線網絡埠，最適合搭配 2.5G 或以上的轉速光纖寬頻使用。

Experience significant performance increase with Wi-Fi 7.

320MHz Channel Bandwidths

Wi-Fi 7 can deliver massive throughput gains thanks to a wider channel and capacity gains from 6GHz spectrum. Wi-Fi 7 can deliver peak rates of over 40 Gbps, a 4X increase over Wi-Fi 6E.

Multi-Link Capabilities

Wi-Fi 7 introduces several multi-link options that can significantly increase throughput and reduce latency. The most powerful multi-link alternative is High-Band Simultaneous Multi-Link, which uses two Wi-Fi radios operating simultaneously in the high bands (5 or 6 GHz), creating one aggregated data pipe to deliver the optimal performance, even in congested areas.

Modulation Evolution

Wi-Fi 7 is standardizing an advanced modulation scheme called 4K QAM, which can boost the peak rates to increase throughput, and capacity compared to Wi-Fi systems using 1K QAM modulation.

Flexible Channel Utilization

This technology advancement is based on preamble puncturing to avoid channels with interference, resulting in an ability to use wider channels also in the face of interference.

Our cutting-edge innovations enable new advanced use cases.

At Qualcomm Technologies, we are at the forefront of this technology evolution, maximizing the potential of what’s possible with Wi-Fi and paving the way for next-level, in-demand user experiences.

Significant capacity increases

Wi-Fi 7 brings extreme data speeds, lower latencies, and increased network capacity thanks to new capabilities designed to support large numbers of users and devices in bandwidth-intensive environments.
