What is Wi-Fi 802.11ac?

802.11ac is Wi-Fi networking standard which provides high-throughput Wireless Local Access Networks (WLAN) on the 5 GHz band. 802.11ac is often referred to simply as “Wireless ac” or “Wi-Fi ac”, much like its predecessors 802.11a/b/g/n are referred to as “Wireless a/b/g/n” or “Wi-Fi a/b/g/n”.

802.11ac is currently the fastest available Wi-Fi standard, offering the fastest data transfer speeds to your devices at home and work.


The 802.11ac standard is capable of theoretical speeds up to 1700 Mbps and beyond. Typical real-world performance is generally around 500Mbps, though faster or slower performance might depend on your router, client device, and environment.

All the newest mobile technology is being built to use 802.11ac.

An 802.11ac router allows your compatible devices to have the best Internet experience. Without an 802.11ac router, your 802.11ac compatible devices would be forced onto slower connections such as 802.11a/b/g/n (depending on you router and device compatibility).
