Features of the Cisco High Density Experience with CleanAir Technology 

Cisco has created an integrated solution with patented hardware and software that has been specifically designed 

to analyze and classify all RF activity. (More than 25 patents have been issued for this technology to date.) Further 

details on CleanAir are available in

The following discussion captures the highlights, significance, and benefits of CleanAir as part of the Cisco High 

Density Experience. 

Detection and identification of interference sources have always been very important, and they increase in 

importance as wireless networks increase in density (more clients, more access points, and more traffic).  

As a critical component of our HDX solution suite, Cisco CleanAir technology provides a lot of detailed information 
about interference. But to facilitate an “at-a-glance” understanding of where interference problems are affecting the 

network, it rolls this information up into a high-level, easy-to- understand metric referred to as Air Quality (AQ).  

AQ is reported at a channel, floor, and system level, and Cisco CleanAir supports AQ alerts, so that you can be 

automatically notified when AQ falls below a desired threshold. 

Air Quality is reported for both “classified” (that is, detected and identified) and ‘”unclassified” (that is, detected but 

unidentified) interference. Information about unclassified interference is included in the AQ report but is excluded 

from AQ index calculations. For improved monitoring capabilities, when the severity of the unclassified category 

exceeds a user-defined threshold, an alarm is generated. 

In a WLAN that has CleanAir technology enabled, devices that have been analyzed and detected are also 

integrated with the visual mapping displays provided by the Cisco Prime

™

 Infrastructure and Mobility Services 

Engine (MSE) management systems. In addition to seeing access points and clients on a map, you can track 

where interference devices exist on the same map. In terms of performance, the ability to see interference devices 

on the map (as well as their zone of impact) lets you determine what access points, clients, and areas of your floor 

space are affected. 

From a security perspective, tracking devices on a map lets you know immediately where to dispatch your security 

personnel. 

In addition to displaying on a map any devices that affect security, you can customize alerts by location - for 

example, a specific floor of your building. This is a powerful feature, since certain devices may be considered a 

threat in some areas of your building - for example, in the trading wing - but not in other areas, such as the 
building’s lobby. 

In addition to flexible deployment, Cisco CleanAir technology offers advanced automated response to interference. 

These automated responses include persistent device avoidance and event-driven radio resource management 

(EDRRM).
