Wireless networking standards that define different capabilities and speeds?

Wireless networking standards that define different capabilities and speeds?

• A. Speed considerations
• B. Band options
• C. 2.4GHz
• D. 802.11n/ac/ax

Answer: (D)

Wireless standards define what a network can do in terms of data rates and features. The set of standards that includes 802.11n, 802.11ac, and 802.11ax specifies those capabilities and the speeds you can expect from Wi‑Fi. Each generation brings improvements: 802.11n introduced MIMO and wider channels to boost throughput; 802.11ac moved to the 5 GHz band with even wider channels and more antenna streams; 802.11ax, also known as Wi‑Fi 6, adds OFDMA and better efficiency for many devices, delivering higher real‑world speeds, especially in crowded environments. So this option best describes the concept because it directly refers to the standards that define performance characteristics of wireless networks. The other choices point to aspects of wireless networking rather than the standards themselves (speed discussions in general, frequency bands, or a specific band like 2.4 GHz).
