Using AirWave to Set up Spectrum Analysis
The spectrum analysis software modules on Dell Networking W-Series AP models AP-105, RAP-5WN, the AP-12x
series, the AP-13x series, and the AP-9x series can examine the radio frequency (RF) environment in which the Wi-Fi
network is operating, identify interference and classify its sources.
The spectrum analyzer is used in conjunction with Dell's Adaptive Radio Management (ARM) technology. While the
spectrum analyzer identifies and classifies Wi-Fi and non-Wi-Fi sources of interference, ARM automatically ensures that
APs serving clients will stay clear of interference.
Individual APs or groups of APs can be converted to dedicated spectrum monitors through the dot11a and dot11g radio
profiles of that AP or AP group, or through a special spectrum override profile.
Each 802.11a and 802.11g radio profile references a spectrum profile, which identifies the spectrum band the radio will
monitor and analyze, and defines the default ageout times for each monitored device type. By default, an 802.11a radio
profile references a spectrum profile named default-a (which configures the radio to monitor the upper channels of the 5
GHz radio band), and an 802.11g radio profile references a spectrum profile named default-g (which configures the radio
to monitor all channels the 2.4 GHz radio band).
Most interference will occur in the 2.4 GHz radio band.
For more information about Spectrum analysis and ARM technology, refer to the Dell Networking W-Series ArubaOS
User Guide at dell.com/support/manuals.
Spectrum Configurations and Prerequisites
The following prerequisites must be in place to configure an AP to run in Spectrum mode in AirWave:
l The AP must be in Manage Read/Write mode.
l The AP’s associated controller must have an RFprotect license and must be running ArubaOS 6.0 or later.
l Dell Networking W GUI Config must be enabled for that AP’s group in the Groups > Basic page.
There are three main situations in which you would set one or more devices to Spectrum mode in AirWave:
