Question: 1 / 525

At what frequency does 802.11g operate?

2.4GHz

802.11g operates at a frequency of 2.4GHz. This frequency is within the unlicensed radio spectrum, meaning that it does not require a license to operate. Additionally, 2.4GHz is the most commonly used frequency for Wi-Fi networks, making it a reliable and widely available option. The other options, while also within the unlicensed spectrum, are not the designated frequency for 802.11g and may cause compatibility issues. Both 2.4GHz and 5GHz (option C) is incorrect as 802.11g only operates at 2.4GHz. Either 2.4 or 5GHz (option D) is also incorrect as it implies that the frequency can be either 2.4GHz or 5GHz, when in fact it can only operate at 2.4GHz. Option B, 5GHz, is incorrect as it is the designated frequency for 802.11a and 802.11n, not 802.11g. Therefore, option A, 2.4GHz, is the correct answer.
