HI Site survey can provide interference info, and WLC(new version) also can does it. Sometimes I notice the interference almost does not exist when we check Interference in WLC(new version), however it shows strong CCI/ACI if we do side survey for the same wireless network. So for the interference, which one we should believe? side survey or WLC(new version)? Thank you

I tend to say site-survey, because the detection on the WLC depends on the type of used AP. There are some models which use CleanAir, which offers a considerably better detection than the models without that feature.
Also keep in mind, some types of interference are very short lived.

Thank you for your reply. I agree. If ap with cleanair and without cleanair work together, site survey would be better, but if all APs have cleanair, WLC would be better, can we say like that?

I think you are correct especially when a unexpected event is there, such as a phone antenna is there. However recently I feel site survey just provide very rough estimate. When site survey shows severe interference, the real network shows working very well. Maybe cisco ekahau can work better.

Just to add... keep in mind that a site survey is a point in time and also varies due to how the algorithm is defined for the thresholds. Ekahau and AirMagnet as an example might take all information even with your ssid's and calculate different than what a controller might. I have used different tools and at times, they all show different things. I think it's really getting use to the different tools and what they can or can't provide.
