Which standard is known as Wi-Fi 6?

• A. 802.11ad
• B. 802.11ax
• C. 802.11ac
• D. 802.11n

Answer: (B)

The main idea here is understanding how the Wi‑Fi generations map to the IEEE 802.11 standards. Wi‑Fi 6 is the branding used for the 802.11ax standard, chosen by the Wi‑Fi Alliance to mark the sixth generation and its improvements in efficiency and performance, especially in crowded environments. The older generations map to earlier standards: Wi‑Fi 4 corresponds to 802.11n, and Wi‑Fi 5 corresponds to 802.11ac, both reflecting their generation-era capabilities like faster speeds and better spectrum use. A different high‑frequency standard at 60 GHz, 802.11ad, isn’t the Wi‑Fi 6 generation—it’s a separate technology often referred to as WiGig. So 802.11ax is the one known as Wi‑Fi 6 because that’s the generation the alliance designated as the sixth, with features such as OFDMA, MU‑MIMO improvements, and higher efficiency.
