• Troubleshoot the physical layer of your WLAN in real-time at remote locations
  • Maintain WLAN performance by proactively identifying sources of interference
  • Perform Spectrum Analysis without dedicated hardware, utilizing your existing Services Platform infrastructure

Spec Analysis

The WLAN Defence Spectrum Analysis module provides the industry's first software only solution to view the physical layer of your wireless network using existing hardware. With Spectrum Analysis network administrators can identify and classify possible sources of interference, such as microwave, Bluetooth, cordless phones and view the impact to the network. Utilizing the same WLAN Defence Services Platform distributed monitoring sensors for WIPS, Network Assurance and Spectrum Analysis, it allows the administrator to troubleshoot the interference problems without having to send a technician with expensive, dedicated Spectrum Analysis hardware to a remote location.

Identify And Classify Interference Sources In Your WLAN

Wireless Local Area Networks operate in the same 2.4 GHz and 5 GHz unlicensed spectrum as numerous other devices, such as cordless phones, Bluetooth headsets, wireless cameras and microwave ovens. These devices may cause minor to severe interference in the Wireless LAN and have an impact to network performance. Often sources are introduced unknowingly. Because the interference may be intermittent troubleshooting is particularly cumbersome and typically must be performed in real time. The WLAN Defence Spectrum Analysis module offers a solution to these problems and does not require additional hardware or new sensors. Using a software-only upgrade of the existing WLAN Defence Services Platform, it is possible to obtain a real time view of the physical layer of the network. Spectrum Analysis can also run in the background and alert the administrator when an interference source is detected so that performance issues can be proactively solved before critical wireless applications are affected.

Spectrum Analysis feature includes detection of:

  • Bluetooth devices
  • Microwave ovens
  • Frequency Hopping interference such as cordless phones
  • Continuous Wave interference such as wireless cameras.
