What is the maximum theoretical speed associated with 802.11ax (Wi-Fi 6)?

• A. 3.5 Gbps
• B. 600 Mbps
• C. 9.6 Gbps
• D. 54 Mbps

Answer: (C)

802.11ax reaches its highest theoretical speed when you combine the widest channel, the most spatial streams, and the highest modulation. Using a 160 MHz channel on the 5 GHz band, with 8 spatial streams and 1024-QAM, you get about 1.2 Gbps per stream. Multiply by eight streams, and the total theoretical rate is 9.6 Gbps. That 9.6 Gbps is the upper bound Wi‑Fi 6 can achieve under ideal conditions. In real networks, practical speeds are lower due to overhead, distance, interference, and device limitations. The other numbers come from older standards or smaller configurations, not the maximum Wi‑Fi 6 rate.
