What technology operates on the 2.4-GHz band and runs at 54 Mbps?

The technology that operates on the 2.4-GHz band and runs at 54 Mbps is indeed the 802.11g standard. This standard was developed to provide higher data rates compared to its predecessor, 802.11b, which only offered speeds up to 11 Mbps.

802.11g uses the same 2.4-GHz band as 802.11b but achieves a maximum throughput of 54 Mbps by utilizing a combination of Orthogonal Frequency Division Multiplexing (OFDM) and Complementary Code Keying (CCK). This makes it significantly faster for wireless networking, while still maintaining backward compatibility with devices that only support 802.11b.

In contrast, options such as Wi-Fi 6 operate on both the 2.4-GHz and 5-GHz bands but are not limited to the 54 Mbps speed; they offer much higher speeds and efficiencies. Similarly, 802.11n operates on both the 2.4-GHz and 5-GHz bands as well and can support higher data rates through multiple-input multiple-output (MIMO) technology. 802.11b, on the other hand, operates only at a maximum of 11 Mbps and does not
