What frequency band does 802.11n operate on?

The correct response indicates that 802.11n operates on both the 2.4 GHz and 5 GHz frequency bands. This dual-band capability is one of the key features of the 802.11n standard, which allows devices to communicate over either band, enhancing flexibility in network design and performance.

By utilizing both frequencies, 802.11n can help mitigate interference that may be present in more congested bands, especially the 2.4 GHz band, which is often shared with other devices like microwaves and Bluetooth devices. Additionally, the 5 GHz band typically offers higher data rates and less interference, making it suitable for high-throughput applications.

This versatility improves overall network performance, allowing users to select the best frequency for their specific needs depending on factors such as distance, interference, and device capabilities.
