Thank you guys.  This is exactly as I suspected, but was never 100% sure.

It actually bleeds the same way any other wifi product does without any 
sort of specialized filtering (including airprism).


Take the size of the channel * 1.5 and that will roughly give you the 
size of the channel plus the mask. A 20Mhz channel for instance will 
have a noticeable bleed that covers 30mhz total from side to side.

The latest firmware actually shows what exact frequency range you're using

I'm using the latest firmware version 5.5.10 and it doesn't show me that. The 
AC firmware running 7.1-rc shows me the full range though.

Thank you,

Is that in airOS 5.6? I remembered seeing it, but I was thinking it was on
the AC radios.
