I have a question/concern with the installation of Cisco Wireless-N access points, specifically with the use of higher gain antenna's. There was an older doc that gave specific instructions to use multiples of 4.92" (NOT TO EXCEED 4 INTERVALS) as a theoretical distance between 2 antenna's on the 2.4 Ghz side. On the 5 Ghz side it states to use 2.36" with the same caveat.
My question is -- what are the ground rules for the newer access points that require 3 antenna's ?
Does Cisco have any guidance with regards to the installation of the higher gain antenna's ?
My gut feeling tells me that the rules are the same since the signal on 2.4 and 5 Ghz has not changed. I also wanted to know how far apart should the 5 Ghz be from the 2.4 Ghz antenna's to avoid any issues.
I attached the older doc as a point of reference.
