Configuring Spectrum Monitors and Hybrid APs
An AP can be provisioned to function as a spectrum monitor or as a hybrid AP. The radios
on groups of APs can be converted to dedicated spectrum monitors or hybrid APs through
the AP group’s 802.11a and 802.11g radio profiles.
Converting an AP to a Hybrid AP
You can convert all APs in an SCALANCE W network into hybrid APs by selecting the
Background Spectrum Monitoring option in the 802.11a and 802.11g radio profiles of an AP.
APs in Access mode continue to provide normal access service to clients, while providing
the additional function of monitoring RF interference. If any AP in the SCALANCE W network
does not support the Spectrum Monitoring feature, that AP continues to function as a
standard AP, rather than a hybrid AP. By default, the background spectrum monitoring
option is disabled.
In the hybrid mode, spectrum monitoring is performed only on the home channel. In other
words, if the AP- channel width is 80 Mhz, spectrum monitoring is performed for 80 Mhz. If
the channel width is 40, spectrum monitoring is performed for 40 MHz channel. In a
dedicated air monitor mode, APs perform spectrum monitoring on all channels.
You can convert APs in an SCALANCE W network to hybrid mode by using the SCALANCE
W UI or the CLI.
In the SCALANCE W UI
To convert an AP to a hybrid AP:
1.
Click the RF link on the SCALANCE W main window.
2.
In the RF section, click Show advanced options to view the Radio tab.
3.
To enable a spectrum monitor on the 802.11g radio band, in the 2.4 GHz radio profile,
select Enabled from the Background Spectrum Monitoring drop-down list.
4.
To enable a spectrum monitor on the 802.11a radio band, in the 5 GHz radio profile,
select Enabled from the Background Spectrum Monitoring drop-down list.
5.
Click OK.
In the CLI
