In a 2.4 GHz Wi-Fi deployment in the United States, an administrator must place several access points on the same office floor so that their signals do not overlap and cause adjacent-channel interference. Which set of channels should the administrator configure on the access points to achieve this?
Channels 1, 6, and 11 are spaced far enough apart in the 2.4 GHz band that their 20 MHz-wide signals do not overlap, eliminating adjacent-channel interference. Using any other channel combinations (such as 2, 7, 12 or 1, 5, 9, 13) would cause portions of the frequency ranges to overlap, reducing throughput for every network in range. Channels 36, 40, and 44 are part of the 5 GHz spectrum and therefore do not solve the problem in a 2.4 GHz deployment.
