Each SM will scan and analyze the spectrum band used by the SM's radio (2.4Ghz or 5Ghz). An analysis of the results can then be used to quickly isolate issues with packet transmission, channel quality, and traffic congestion caused by contention with other devices operating in the same band or channel.ĪP radios that gather spectrum data but do not service clients are called spectrum monitors, or SMs.
The spectrum analysis software modules on APs that support this feature are able to examine the radio frequency (RF) environment in which the Wi-Fi network is operating, identify interference and classify its sources. Microwave ovens, cordless phones, and even adjacent Wi-Fi networks are all potential sources of continuous or intermittent interference. Wireless networks operate in environments with electrical and radio frequency devices that can interfere with network communications.
