Mixing AP clean-air and non on same floor

We are planning on adding additional LW APs to one of our schools.

Currently we have 50 1142 controlled by a 5508 WLC across 3 floors.  We plan on adding 35-50 new 2702 AP.

 

I was reading another post on mixing APs, and was wondering if we are going to run into problems by having a mix of clean-air and non-clean-air APs in the same location?

 

If that is the case, why is it a problem, and is there a solution?

 

Much thanks,

Dan

Make sure you understand the power draw requirement for the 2702 AP.  You need 20.0w PoE for this AP to support 802.11ac.  You can, however, operate this AP in 15.4w but this means that the MIMO and MCS rates drop down to 802.11n speed. 

 

In regards to mixing CleanAir with non-CleanAir, it will totally depend on your environment.  The benefit of CleanAir comes evident when you have numerous non-WiFi interference like microwave ovens, Bluetooth, wireless microphones, DECT phones, etc.  You'd want CleanAir to be there so when these non-WiFi interference becomes "disruptive", CleanAir can alleviate the situation by changing channels.  Because 1140 doesn't support CleanAir, 1140 can see the interference but can't do anything.

We use both clean air and non

We use both clean air and non clean air APs and we have some areas where we have turned off clean air where there is a mix of both. I think this is regarded as best practice as it can affect the effectiveness of RRM especially in high density deployments.

However, we do have one or two areas with low density deployments where we mix both types and it doesn't appear to be giving us any particular issues.

Anyone official answer from

Anyone official answer from Cisco on this?  Also, what is considered a "low density" deployment?
