I wouldn't use or allow a four channel pattern at all. You will get more overlap than using a 3 pattern. None of my installs have I ever had a need to even look at doing a four channel deployment. All of my wireless install was implemented using channels 1, 6, 11.
This will create more interference problem than you think... most of other 2.4GHz devices will operate in CH1, CH6 & CH11 & everyone of these devices will interfere with two of your channel & each of your AP will interfere with two of those devices.
i am not referring to channel 14 in my question. i am talking about frequency re-use pattern of channels 1 to 11 with four APs (4 channels in range from 1 to 11).
Ok, if this is what you are talking about then I wouldn't recommend any of your "channel plans" because it this is going against technical specifications.
Exactly what are you trying to accomplish? Do you have a WLC?
If you want to minimize co-channel interferrence, you need to look at disabling lower data rates like 11 Mbps and below. In some cases, you might want to consider disablling 12 Mbps and below and make 18 as Mandatory and make the rest as Supported.
