What is the standard frequency for 802.11g Wi-Fi?

The standard frequency for 802.11g Wi-Fi is 2.4 GHz. This frequency band is utilized to provide compatibility with earlier standards such as 802.11b. Operating at 2.4 GHz allows 802.11g devices to communicate with those older standards while also enabling higher data rates up to 54 Mbps under optimal conditions, combining better performance with broader compatibility.

In the context of Wi-Fi standards, 2.4 GHz is favored for its longer range and better penetration through obstacles compared to higher frequency bands. Though it is prone to more interference due to other devices, such as microwaves and Bluetooth devices operating in the same frequency range, it remains the most commonly used band for many wireless networks.

Options such as 5 GHz are associated with other Wi-Fi standards like 802.11a and 802.11n, which offer different advantages such as faster speeds and less interference. Frequencies like 900 MHz and 1.2 GHz are not standard for general Wi-Fi operations and typically relate to other communication technologies or specialized applications, making them irrelevant when discussing 802.11g.
