300-120 WLSI: Implementing Cisco Wireless Advanced Solutions

Cisco CleanAir refers to non-802.11 RF sources operating in the Wi-Fi spectrum as interferers. It detects, classifies, and reports these foreign sources because they can affect wireless performance. BLE tags can be one specific signal-source category, but they are not the general CleanAir term for all non-802.11 devices; the encompassing classification is interferers.
