Spectrum Analysis
Wireless networks operate in environments with electrical and radio frequency devices that can interfere with
network communications. Microwave ovens, cordless phones, and even adjacent Wi-Fi networks are all
potential sources of continuous or intermittent interference. The spectrum analysis software modules on APs
that support this feature examine the radio frequency (RF) environment in which the Wi-Fi network is
operating, identify interference and classify its sources. An analysis of the results quickly isolate issues with
packet transmission, channel quality, and traffic congestion caused by contention with other devices operating
in the same band or channel.
AP radios that gather spectrum data but do not service clients are called spectrum monitors, or SMs. Each SM
scans and analyzes the spectrum band used by the SM's radio (2.4Ghz or 5Ghz). An AP radio in hybrid AP mode
continues to serve clients as an access point while analyzing spectrum analysis data for the channel the radio
uses to serve clients. You can record data for both types of spectrum analysis devices, save that data, and then
play it back for later analysis.

Understanding Spectrum Analysis
The table below lists the AP models that support the spectrum analysis feature. Single-radio mesh APs do not
support the spectrum analysis feature; if an AP radio has a virtual AP carrying mesh backhaul traffic, no other
virtual AP on that radio can be configured as a spectrum monitor. However, dual-radio mesh APs can have the
client access radio configured as a Spectrum monitor or hybrid AP while the other radio supports mesh
backhaul traffic.
