Spectrum Analysis, specifically Radio Frequency (RF) Spectrum Analysis, is the process of measuring and displaying the variation of the amplitude and/or power level of radio frequency signals over a defined range of frequencies.
The reasons for performing spectrum analysis of the 2.4GHz and 5GHz WiFi RF bands include the detection and identification of RF interference sources and, more generally, the assessment, characterisation and analysis of all significant signals within a given band.
The ultimate goal of RF Spectrum Analysis for WiFi networks is the identification of Physical-layer (RF layer) conditions which might degrade the operation of a WiFi network.
