What are the two frequency bands commonly used for Wi-Fi?

The two frequency bands commonly used for Wi-Fi are 2.4 GHz and 5 GHz. These bands are important as they offer different advantages and characteristics for wireless networking. The 2.4 GHz band is known for providing a greater range and better penetration through walls and obstacles, making it suitable for larger areas or homes with multiple rooms. However, it is often more congested due to the presence of other devices operating in the same frequency range, such as microwaves and Bluetooth devices.

On the other hand, the 5 GHz band is less crowded, which can lead to faster speeds and improved performance, especially in environments with many competing devices. This band typically has a shorter range compared to 2.4 GHz but provides higher data transfer rates, making it ideal for high-bandwidth activities like streaming and gaming.

The other options present frequency bands that are either outdated or not commonly associated with Wi-Fi technology. For instance, 1.2 GHz and 5.8 GHz are not standard for conventional Wi-Fi usage. Additionally, 2.0 GHz and 6 GHz are not recognized as typical bands; while 6 GHz is beginning to be utilized in Wi-Fi 6E, it is not yet as universally applicable as the
