Which frequency bands does the wireless standard typically operate in?

The reason that the second option is correct revolves around the frequency bands commonly used in modern wireless networking standards, particularly Wi-Fi. The 2.4 GHz and 5 GHz bands are well-established frequencies for Wi-Fi technologies, specifically in standards such as 802.11n, 802.11ac, and 802.11ax.

Furthermore, the introduction of the 6 GHz band with Wi-Fi 6E has expanded the available spectrum for wireless communication, providing more channels and reducing congestion. This broadens the capacity for devices to connect simultaneously, thus enhancing overall network performance.

The other options present frequency bands that either include incorrect values not associated with the standard wireless protocols or do not match the frequency allocations designated for popular Wi-Fi standards. Therefore, understanding the correct frequency bands is crucial for configuring and optimizing wireless networks efficiently.
