3.8 Spectrum Analysis

Spectrum analysis features supported by the AP are as follows:



Identifies interference sources such as baby monitors, Bluetooth devices, digital cordless

phones (at 2.4 GHz frequency band only), wireless audio transmitters (at both the 2.4

GHz and 5 GHz frequency bands), wireless game controllers, and microwaves.



Works with eSight to locate and perform spectrum analysis on interference sources.
