Which Wi-Fi standard supports both 2.4 GHz and 5 GHz frequency bands?

The choice of Wi-Fi 6 as the correct answer is based on its ability to operate on both the 2.4 GHz and 5 GHz frequency bands. Wi-Fi 6, which is also known as 802.11ax, enhances the performance of wireless networks while maintaining compatibility with previous standards. This dual-band capability allows for better throughput and more effective handling of multiple devices within a network, making it an excellent option for dense environments like homes, office spaces, and public venues.

Additionally, Wi-Fi 6 includes features such as Orthogonal Frequency Division Multiple Access (OFDMA) and improved Multi-User Multiple Input Multiple Output (MU-MIMO), which further optimize the use of both frequency bands to promote high data rates and reduced latency for connected devices. This ensures that users can experience faster internet speeds and a more reliable connection regardless of which band their device connects to.

On the other hand, while the other standards mentioned in the choices do have specific capabilities, they may not support dual-band frequencies in communication. For instance, Wi-Fi 6E extends Wi-Fi 6 capabilities into the 6 GHz band, but it is specifically designed for that new frequency range and doesn't emphasize the dual-band aspect as directly as Wi-Fi
