Which standard combines 2.4 GHz and 5 GHz with speeds up to 9.6 Gbps?

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

Answer: (A)

802.11ax, known as Wi‑Fi 6, is the standard that operates on both 2.4 GHz and 5 GHz and can reach a theoretical maximum of about 9.6 Gbps. It achieves this through enhancements like OFDMA, uplink and downlink MU‑MIMO, wider channel usage (up to 160 MHz on the 5 GHz band), and higher-order modulation (1024‑QAM). These features boost efficiency and throughput, especially in dense environments where many devices share the spectrum. Other standards either stick to a single band or offer lower peak speeds, such as 802.11ac (primarily 5 GHz with lower max rates) or earlier standards like 802.11n and 802.11b, which don’t reach these combined-band, high-throughput capabilities.
