What are Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax), and what is a key improvement of Wi-Fi 6?

• A. Wi-Fi 5/802.11ac and Wi-Fi 6/802.11ax are generations of wireless standards; Wi-Fi 6 offers higher throughput, better capacity, and lower latency in crowded environments.
• B. Wi-Fi 6 is slower than Wi-Fi 5.
• C. Wi-Fi 6 uses less secure encryption than Wi-Fi 5.
• D. There is no difference between Wi-Fi 5 and Wi-Fi 6.

Answer: (C)

Wi‑Fi 5 (802.11ac) and Wi‑Fi 6 (802.11ax) are generations of wireless networking standards. Wi‑Fi 5 pushed higher speeds in the 5 GHz band, focusing on fast single-device throughput. Wi‑Fi 6 builds on that by making the whole network more efficient, especially when many devices are connected at once. A key improvement is higher capacity and lower latency in crowded environments, achieved through technologies like OFDMA (splitting channels to serve multiple devices at the same time), MU‑MIMO (more simultaneous streams for multiple clients), and better power-saving features to extend device battery life. Encryption security has not been reduced with Wi‑Fi 6; modern setups can use stronger protections (like WPA3), so the idea that Wi‑Fi 6 uses less secure encryption isn’t accurate. Overall, Wi‑Fi 6 makes networks behave better when lots of devices compete for bandwidth, not just faster speeds for a single device.
