What standard operates exclusively in the 5 GHz spectrum and can achieve a theoretical speed of up to 6.9 Gbps?

The standard that operates exclusively in the 5 GHz spectrum and can achieve a theoretical speed of up to 6.9 Gbps is 802.11ac. This Wi-Fi standard is designed to enhance performance in high-density environments and improve overall user experience due to its advanced technologies, such as beamforming and Multi-User MIMO (MU-MIMO).

Wi-Fi 6, also known as 802.11ax, does indeed work in both the 2.4 GHz and 5 GHz spectrums, and while it offers improvements over 802.11ac in terms of speed and efficiency (with maximum theoretical speeds beyond 9.6 Gbps), it does not operate exclusively in the 5 GHz band.

Although 802.11ax does include advanced features that allow it to perform better in congested areas, it does not fit the criteria of being limited to the 5 GHz spectrum. Wi-Fi Protected Access 2 (WPA2) is a security protocol used to secure wireless networks and does not pertain to speed or frequency bands.

In summary, 802.11ac operates solely in the 5 GHz band and is optimized for achieving high-speed connections, making it the correct choice for this
