Explanation

In a 2.4GHz WLAN environment, channels 1, 6, and 11 are recommended for use simultaneously to avoid co-channel interference because these channels do not overlap with each other. Each of these channels is separated by enough frequency space to ensure that the signals do not interfere, which is not the case with other channel combinations.
