My installation has 4 wired AP´s with 8dbi antennas. They are in a equidistante square position in a campus. Because I have only 3 non-overlaped channels, what is the best separation (in metres) between them?
It's pretty much dependent on the environment, the height of the antennas and line-of-sight, reflecting objects, etc.
Only a good site survey is going to answer your question.
What you can do is lower the output power (versus increasing the distances) according to the coverage overlap.
Or, put two diagonal corners on one channel, with the other two corners each on their own channels. You may be able to put them all on one channel and use a roaming config ... it all depends on how the signal quality / strengths come out on the survey.
It shoudnt be in meters ut should be in dB. If you have 2 access points on the same channel you should have 20dB difference between then to limit interference. If thats 100 meters or 1 meter .. 20 dB is 20 dB ..
