27 Managing spectrum guard
To use spectrum guard, first enable spectrum analysis. Spectrum analysis evaluates channel quality
and detects interferences on monitored channels. The following interferences can be detected:
• Microwave ovens
• Bluetooth
• Fixed-frequency (video)
• Cordless phone
• Microsoft xbox
Spectrum guard module provides the following:
• Automatically switches the working channel of a radio, based on channel quality, to make sure
the radio is always operating on the optimum channel.
• Summarizes and displays the spectrum analysis data in graphs and charts. You can adjust the
configurations or the WLAN layout to obtain better network performance.
This chapter describes how to configure and use the spectrum guard module.
Setting the operating mode of an AP
To use spectrum analysis, make sure the AP operates in hybrid or monitor mode. If the AP operates in
normal mode, the radio detects only the operating channel.
To set the operating mode of an AP:
1. Click the Service tab.
2. From the navigation tree, select WLAN Manager > Resource Management > Fit APs.
The Fit AP List page appears.
3. Click the label of the AP.
The fit AP details page appears.
4. In the Action menu located on the right of the page, click Modify AP Template.
The Modify AP Template page appears.
5. Set the operating mode to Hybrid or Monitor.
NOTE:
•
To switch between the hybrid mode and monitor mode, first change the operating mode to normal
mode.
• To view the Signal Strength by SSID statistics, set the AP to operate in monitor mode.
Configuring spectrum analysis
To configure spectrum analysis on a Comware-based AC, make sure the AC has registered the rfp
license.
