What is the typical frequency range for Wi-Fi?

The typical frequency range for Wi-Fi is indeed 2.4 GHz and 5 GHz. These two bands are standardized for most Wi-Fi networks, including the popular IEEE 802.11b/g/n (which primarily uses the 2.4 GHz band) and IEEE 802.11a/n/ac (which operates in the 5 GHz band).

Using the 2.4 GHz band allows for a greater range, but it also means more potential interference from other devices that operate on the same frequency, such as microwaves and cordless phones. On the other hand, the 5 GHz band offers faster data rates and less interference but has a shorter range due to its higher frequency which has difficulty penetrating solid objects, such as walls.

The other frequency ranges provided in the choices do not accurately reflect the common standards used in Wi-Fi technology. For instance, the range of 1.2 GHz to 2.5 GHz does not encompass the primary bands used for Wi-Fi. The 5 GHz and 10 GHz option exceeds the typical frequency ranges established for existing Wi-Fi standards. Lastly, the 900 MHz and 2.4 GHz option mixes a lower frequency that is not commonly used for standard Wi-Fi operations with the correct
