Sample channel selections
For example, when operating in 802.11b mode, the M220 supports the following 14 channels
in the 2.4 GHz band:
However, the number of channels available for use in a particular country are determined by
regional regulations. The following table shows the number of channels that are available in
North America and Europe:
Since the minimum recommended separation between overlapping channels is 25 MHz (in
other words, they must be at least five channels apart) the recommended maximum number of
overlapping APs you can have in most regions is three. The following table gives examples
relevant to North America and Europe for channels in the 2.4 GHz band:
