What frequency is associated with 802.11b?

The frequency associated with 802.11b is 2.4 GHz. This standard, which is part of the IEEE 802.11 family of wireless networking protocols, operates in the 2.4 GHz frequency band, allowing for a maximum theoretical data rate of 11 Mbps. This frequency was chosen because it provides a good balance between range and speed, making it suitable for various wireless applications, particularly for home and small office environments.

The 2.4 GHz band is also utilized by other devices, such as microwaves and Bluetooth devices, which can lead to potential interference; however, it remains one of the most widely used frequency bands for Wi-Fi due to its extended range compared to higher frequencies.

In contrast, the other frequencies listed are associated with different wireless standards or technologies. For example, 5.0 GHz is commonly associated with the newer 802.11a and 802.11n standards, which offer faster speeds but shorter range. Frequencies such as 1.8 GHz and 3.5 GHz are not standard for Wi-Fi technologies and are utilized in other communication systems, which makes them irrelevant to 802.11b.
