Unfortunately there's not much you can do there. &nbsp;I would happily confirm that you're going to be suffering from lots of co-channel interference there which will cause drop-outs all day.<br />
<br />
I'd suggest that if you have an AP on the same channel with a RSSI of around -85dBm it's not going to affect you too much, but anything higher than that will give you issues.<br />
<br />
Out of interest, where are you located?

<div>
So anything &nbsp;below -85 in the same channel really wont impact me if its in the same channel is that a fair statement?

I work at a school and we have between 30 and 60 AP's at each school.<br />
We have a high concentration in order to get 20 or more kids on line in each room.<br />
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)<br />
<br />
All my devices must work on the 2.4Ghz band so I am limited to &nbsp;channels..<br />
<br />
my question is.. <br />
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)<br />
<br />
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 &nbsp;-80db on the same channel.. &nbsp;I need some hard numbers so management will understand that external forces are causing connections to drop not the equipment/design.<br />

Wireless congestion  cochannel interference and signal strength

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.
