Improving Wireless LAN security and performance with new Spectrum Analyzer

AirMagnet announced the latest version of Spectrum Analyzer, the industry’s leading solution for identifying RF interference sources that impact the performance and security of Wi-Fi networks.

Spectrum Analyzer 3.1 includes support for Microsoft Vista, an upgraded help module for mitigating interference issues, a new instant replay feature, SNMP trap support, and much more. The combination of new features give IT managers a more pragmatic, real-world approach to improving WLAN performance and security by enabling them to detect, identify, and locate sources of interference or malicious attacks at the physical layer of the network.

AirMagnet’s Spectrum Analyzer proactively identifies, classifies, and finds sources of RF interference that impact the performance of Wi-Fi networks. Unlike earlier generations of spectrum analyzers, AirMagnet’s Spectrum Analyzer provides an IT-friendly user interface with a rich set of real-time graphical displays to help IT managers analyze the spectrum. Using patented spectral fingerprinting techniques to measure, analyze, and display critical spectrum events and log all interfering devices in real-time, Spectrum Analyzer’s system automatically recognizes a wide variety of wireless devices — such as Bluetooth, cordless phones, microwaves, analog video cameras, RF jammers and more — which can be viewed by time and channel for easy tracking and management.

New to Spectrum Analyzer 3.1

” Vista Support — IT managers can now install and use Spectrum Analyzer on Microsoft Vista.
” Help Module Upgrade — Additional information on interference sources such as common names, severity of interference, recommended actions, and more, allow an IT manager to quickly resolve RF spectrum issues and ease troubleshooting of wireless networks.
” Instant Replay — IT managers can review the most recent spectrum information through a playback feature (as if it were being viewed live for the first time), without interrupting the current Live Capture session. This allows for detailed post-collection analysis.
” SNMP Traps — IT managers can send traps to an existing SNMP network management system when a new interfering device is detected based on a user policy. This allows an organization to instantly recognize when a non-authorized device is using spectrum resources and potentially causing interference.
” Signal to Noise Ratio (SNR) Charts — These charts allows IT managers to easily identify the devices with poor signal to noise ratio by generating a color-coded bar chart that displays the SNR (the ratio of a given transmitted signal to the background noise on the channel) for each channel that has access points.
” Additional Features — Device classification (in-network, known, unknown), date formats, plot backgrounds and updated spectrum alerts.
