Your company has recently deployed a set of wireless IP cameras in the warehouse. The deployment area has legacy equipment that operates on the 2.4GHz band, which seems to be causing interference with the camera signals. Which wireless channel would be the best choice to minimize interference with the legacy equipment?
In the 2.4GHz band, channels 1 through 11 are available for use in North America. To prevent signal overlap and reduce adjacent-channel interference, the best practice is to use channels 1, 6, or 11, as they are spaced far enough apart not to interfere with each other. Channels like 3 and 9 would overlap with this standard three-channel plan, causing potential interference. Channel 13 is not authorized for Wi-Fi use in North America, though it is used in other regions. Therefore, choosing one of the non-overlapping channels is the best strategy, making Channel 11 the correct choice among the given options.
