Cisco CleanAir is a revolutionary technology and industry first that provides IT managers with access to rich spectrum information that is automatically gathered on every non-802.11 interference source. The spectrum intelligence provided by CleanAir technology enables a new level of spectrum management.
The Clean Air technology is only supported on the Cisco 3500 series APs and the controller code level will need to be at 7.0 to take advantage of the features. Basically, they took the general code from the Cisco Spectrum Expert and wrote it to the chipset on the 3500 series APs.
