Which wireless modes are supported by the 2.4 GHz band?

The 2.4 GHz band supports specific wireless modes that include 802.11b, 802.11g, and 802.11n. Each of these standards operates effectively within the 2.4 GHz frequency range.

802.11b was one of the earliest standards established for wireless LANs and operates at speeds up to 11 Mbps. 802.11g subsequently enhanced this capability, allowing for speeds of up to 54 Mbps while still utilizing the same 2.4 GHz band, ensuring compatibility with 802.11b devices.

802.11n further improved performance with technologies such as Multiple Input Multiple Output (MIMO) which uses multiple antennas to enhance data throughput and range. While 802.11n can also operate on the 5 GHz band, its deployment in the 2.4 GHz band is significant, allowing for increased speeds and reliability.

In contrast, standards like 802.11a and 802.11ac do not function on the 2.4 GHz band; they operate solely in the 5 GHz band. 802.11ax, also known as Wi-Fi 6, is capable of operating in both 2.4 GHz and 5 GHz bands
