In the 2.4 GHz frequency band used by 802.11b/g/n Wi-Fi networks, channels are spaced 5 MHz apart but each channel has a bandwidth of 22 MHz, causing overlap with adjacent channels. The commonly accepted non-overlapping channels in the 2.4 GHz range are 1, 6, and 11. Among these, channel 1 ranges from 2.401 GHz to 2.423 GHz, channel 6 ranges from 2.426 GHz to 2.448 GHz, and channel 11 ranges from 2.451 GHz to 2.473 GHz. These channels are spaced far enough apart that they do not overlap with each other. Therefore, channels 11 and 6 are non-overlapping.
