What are the frequency bands used in wireless networking?

• A. 2.4 GHz, 5 GHz, 6 GHz
• B. 1.2 GHz, 3.2 GHz, 6.2 GHz
• C. 2.5 GHz, 5.5 GHz, 7 GHz
• D. 2.1 GHz, 4 GHz, 8 GHz

Answer: (A)

The frequency bands commonly used in wireless networking are 2.4 GHz, 5 GHz, and 6 GHz. These frequency bands are part of the IEEE 802.11 wireless standards, which are widely used for Wi-Fi networks. The 2.4 GHz band has been traditionally used for Wi-Fi since the early days of wireless networking. It offers a longer range and better penetration through walls compared to higher frequencies, but it is also more susceptible to interference from other devices, such as microwaves and Bluetooth devices. The 5 GHz band was introduced to alleviate congestion in the 2.4 GHz band, offering higher data rates and less interference as it has more non-overlapping channels available. This band is especially useful in environments with many devices, such as homes and offices. The introduction of the 6 GHz band marks a significant step in wireless networking, as it allows for even wider channels and more capacity, thus improving performance in environments with high demand for bandwidth. The other frequency options listed do not align with the standard frequency bands used for wireless networking, which is why they do not apply to the context of the question.
