4. Channels occupied by coverage areas of APs should comply with certain
specifications. APs in nearby coverage areas cannot use the same channel;
otherwise, co-channel interference would be caused during signal
transmission of APs. Take 2.4G band as example, to utilize band resources
to the maximum extent, the most common method is to select three
non-overlapped channels (channels 1, 6, and 11) as the operating band of
the whole system. the channels1, 6, and 11 are mutually adjacent and
partially overlapped (as shown in the figure below) so as to eliminate blind
spots and avoid co-channel interference while obtaining the largest
coverage area.
5. APs that implement wireless roaming network must use the same network
name (SSID) and IP address in the same network segment. Otherwise,
wireless customers cannot implement the roaming function.
