Which wireless standard supports speeds of 22/54 Mbps at 2.4 GHz?

The wireless standard that supports speeds of 22/54 Mbps at 2.4 GHz is 802.11g. This standard was introduced to provide a means of achieving higher data rates compared to its predecessor, 802.11b, which offers a maximum throughput of up to 11 Mbps. 802.11g is backward compatible with 802.11b and operates in the 2.4 GHz band, allowing devices that comply with either standard to communicate effectively.

By utilizing the same frequency as 802.11b, 802.11g achieves a maximum theoretical data rate of 54 Mbps through the use of Orthogonal Frequency Division Multiplexing (OFDM) technology, which improves speed and efficiency. Additionally, the 22 Mbps figure often refers to more practical speeds experienced in real-world conditions, taking into account network overhead and environmental factors.

In summary, 802.11g is the correct answer because it specifically supports the 22/54 Mbps data rates at the 2.4 GHz frequency, highlighting its role in enhancing wireless connectivity for users seeking higher bandwidth while maintaining compatibility with older 802.11b devices.
