What frequencies are available for 802.11b/g wireless cards?

The 802.11b/g wireless standards operate in the 2.4GHz band, specifically utilizing channels that range from 2412MHz to 2472MHz. The frequency of 2412MHz corresponds to channel 1, while 2422MHz corresponds to channel 3. These channels are part of the designated frequency ranges for the 802.11b/g standards.

In this case, the correct response identifies one of the valid frequencies specifically employed by Bluetooth and some Wi-Fi devices.

The other frequency given, 5800MHz, falls outside the range used by 802.11b/g protocols, as it belongs to the 802.11a standard commonly used for higher frequency operation in the 5GHz band. Therefore, while 2412MHz and 2422MHz are indeed valid frequencies for 802.11b/g, the option that includes 5800MHz does not fit within the operating range for those specific wireless standards.
