What are the three nonoverlapping channels that 802.11b and 802.11g support?3, 6, and 91, 7, and 111, 6, and 113, 7, and 10

The three nonoverlapping channels that 802.11b and 802.11g support are channels 1, 6, and 11.

In the 2.4 GHz frequency band used by these wireless standards, channels are spaced at 5 MHz intervals, but due to the width of the channels (which is 20 MHz), most channels overlap. The channels 1, 6, and 11 are specifically chosen because they do not overlap with each other, allowing for reliable and interference-free communication when multiple networks are in close proximity.

This is particularly important in environments where multiple Wi-Fi networks operate simultaneously, such as in urban areas or office settings, to minimize interference and maximize performance.
