What frequency does 802.11n operate on?

The 802.11n wireless networking standard operates on both the 2.4 GHz and 5.0 GHz frequency bands, providing flexibility in terms of range and speed. However, the emphasis on the 5.0 GHz band is significant for its ability to support higher data rates and offer less interference from other devices, which often operate on the 2.4 GHz band. When selecting 802.11n devices, users can take advantage of the distinctly better performance typically associated with the 5.0 GHz band, especially in environments with many competing signals. Therefore, while it's important to note that 802.11n can utilize both frequency bands, the recognition of the 5.0 GHz as a particularly advantageous option highlights its role in maximizing network efficiency and performance.

Options that mention frequencies like 1.2 GHz or 6.0 GHz do not apply to the 802.11n standard, as these frequencies are not used for Wi-Fi networks, making them incorrect choices.
