Wi-Fi Standards

802.11ac-class device wireless speeds are often advertised as AC followed by a number, that number being the highest link rates in Mbit/s of all the simultaneously-usable radios in the device added up.

瞭解有關 Wi-Fi 標準的所有資訊，包括 IEEE 802.11ac、802.11ax 和詳細的無線標準表。 瞭解這對您的無線網路效能有何影響。

Discover major Wi-Fi standards such as 802.11be, 802.11ax, and 802.11ac. This article helps you compare their differences and ideal use cases.

當Wi-Fi 6（802.11ax） 裝置連接到Wi-Fi 5 （802.11ac） 無線路由器時，連接將預設使用802.11ac標準的功能。 對於 802.11ac，最高速度可以達到 1.73Gbps（這是理論上的）。

什麼是 802.11ac？ 802.11ac 是一種 無線網路標準。 更具體來說，它是 IEEE 802.11 協定組用於實現無線區域網路（WLAN）電腦通訊的第五代協定。 802.11ac 標準於 2014 年發布，旨在於 5 GHz 頻段提供高吞吐量的無線區域網路。

This page provides a breakdown of the WLAN 802.11ac data rates. The following table outlines the 802.11ac data rates for 20MHz, 40MHz, 80MHz, and 160 MHz bandwidths across various modulation and coding schemes (MCS).

Similarly, 802.11ac technology uses 433Mbps per spatial stream (in the 5GHz band), so 802.11ac theoretical maximum speeds are 433Mbps, 866 Mbps, etc., in multiples of 433.
