I need to intall 04 Aps in an area where all of them have contact. I now know that the best practice is to use the three channels combination, but what would be the best way to do it? How could I use the 4 APs considering that two of them will be in an meeting room where I need to guarantee around 60 connections?
I do not know the scale of your map, but can you try to play with the power level (reduce AP power level to a minimum) and the antenna type (use a low gain patch antenna to isolate the beams from each other)?
Thanks for your feedback about the power levels, do you know where can I find the material about it? And about the antenna we haven't purchased no external antennas, so I believe that will have to deal with power level.
You can do it this way:
AP-A Channel 1
AP-B Channel 6
AP-C Channel 11
AP-D Channel 1
AP-A & AP-D is where you would reduce the TX power.
