Spectrum Analysis

The Spectrum Analysis module gives you a tool to identify and locate interference sources on your wireless network. The analysis is conducted using only AirDefense software; no extra hardware is required.

Note

You must have a valid Spectrum Analysis license for each sensor that you wish to conduct an analysis from.

Spectrum Analysis supports two modes of operation:

• Background Scanning
  • Part-time scanning of power spectral density (Layer 1), while sensor continues to scan for WIPS (Layer 2).
  • Generate 'RF Spectrum Analysis' alerts (Bluetooth, Microwave, Frequency Hopper, Continuous Wave)
• Dedicated Spectrum View
  • Sensor temporarily dedicated to Spectrum Analysis
  • While in Spectrum View the sensor provides no protocol analysis (after user-configured time period, sensor defaults back to WIPS)
  • Scanning options:

• Full Scan Mode—scan full 2.4-2.5 GHz and 4.9-6.1 GHz spectrum to identify presence of interference (scan more channels, spend less time on each channel)
• Interference Scan Mode—scan specific bands to classify type of interference source (scan fewer channels, spend more time on each channel)

The Spectrum Analysis topic in Menu chapter fully explains how to use Spectrum Analysis.
