Again with the APs in hallways?
they are on the walls (incorrectly installed because of the antenna pattern)
and THEY ARE FACING EACHOTHER!
Even if CCI weren’t an issue (it is) ACI (Adjacent Channel Interfernce) is more than likely gonna be an issue.
This is repeated about every 50ft down the halls.
Can you imagine having someone screaming in your face EVERY SINGLE MINUTE OF EVERY SINGLE DAY?
All one can do at this point is ¯\_(ツ)_/¯.
