Which Wi-Fi standard provides data transfer rates up to 54Mbps on the 2.4GHz frequency?

The Wi-Fi standard that provides data transfer rates up to 54Mbps on the 2.4GHz frequency is 802.11g. This standard was developed to enhance the previous standard, 802.11b, which offered lower maximum data transfer rates.

802.11g operates in the same 2.4GHz band as 802.11b, allowing it to maintain backward compatibility with devices using the older standard. With a maximum throughput of 54Mbps, 802.11g improves the speed of wireless communication significantly, making it suitable for various applications such as streaming and online gaming during the time of its adoption.

The other standards mentioned either provide different maximum speeds or operate at different frequencies. For instance, 802.11b has a maximum throughput of 11Mbps, while 802.11n supports higher data rates and can operate on both 2.4GHz and the 5GHz frequency bands, and 802.11ac primarily operates on the 5GHz frequency with significantly higher data rates. Thus, 802.11g is correctly identified as the standard that meets the specified criteria.
