Thanks for the quick replies everyone.

Nicolas,

When you mention "but 20 meters from the AP on a horizontal plane, you'll get nothing" is the 20 meters the maximum distance of the "dome" so to speak? The library has a very high ceiling and we've already recommended no placement on the ceiling. We'll most likely place them in a grid like system on the concrete pillars as cabling and conduit routing are a bit difficult.

Thanks,

Craig

The number "20" was a random value. I actually never measured how many meters the coverage goes when the AP is placed on a wall because it's not supposed to :-)

I don't know the maximum heigth that people put the AP and still had good coverage

Hello;

I have a deployment of 5508 WLCs and 3500i APs.  I have CleanAir configured and enabled.  I am constantly getting Interference threshold violations, however, when I look at the CleanAir Interferer Count in WCS there are no devices listed.  Could it be that since these APs are in local mode that the interferer is not on channel 1, 6, or 11? 

Thanks

Stan

Hi Amer, please post your question directly in the forum. This "ask the expert" event is only about clean air (which is not your question) and is also closed since some time.
