I work at a school and we have between 30 and 60 AP's at each school.
We have a high concentration in order to get 20 or more kids on line in each room.
The issue I am having is dropped connections due to cochannel interference from my other AP's as well as those outside the schools.(I am in the city)
All my devices must work on the 2.4Ghz band so I am limited to channels..
my question is..
What is the delta I should be shooting for when I have 2(or more) AP on the same channel(or other access points outside my school)
I am getting at least -70db in all my classrooms but some of the rogue AP's as well as others in my organization might be sitting at -80db on the same channel.. I need some hard numbers so management will understand that external forces are causing connections to drop not the equipment/design.
