Which standard operates at 5 GHz and supports 54 Mbps?

The standard that operates at 5 GHz and supports 54 Mbps is 802.11a. This wireless networking standard was developed to provide higher data rates and less interference than the older standards that operate in the 2.4 GHz band.

802.11a operates specifically in the 5 GHz frequency range, which allows it to offer faster speeds by using a different modulation technique than its predecessors. It achieves a maximum data rate of 54 Mbps, making it suitable for environments where higher bandwidth is necessary.

In contrast, 802.11b and 802.11g operate at 2.4 GHz, with 802.11b supporting data rates up to 11 Mbps and 802.11g reaching a maximum of 54 Mbps while also being backward compatible with 802.11b. 802.11n can operate in both the 2.4 GHz and 5 GHz bands and offers even higher speeds through MIMO (Multiple Input, Multiple Output) technology. However, it does not specifically define operation solely at 5 GHz and offers a range of maximum speeds depending on the configuration.

Therefore, the defining characteristics of 802.11a are its operational frequency at 5 GHz and its maximum
