Setting up Spectrum Analysis in AirWave
The spectrum analysis software modules on Dell PowerConnect 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 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.

Spectrum Configurations and Prerequisites
The following prerequisites must be in place to configure an AP to run in Spectrum mode in AirWave:
 The AP must be in Manage Read/Write mode.
 The AP’s associated controller must have an RFprotect license and must run ArubaOS 6.0 or later.
 Dell PowerConnect 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:
 Dell PowerConnect W AP Groups running permanently with the default Spectrum profile
 Individual APs running temporarily in Spectrum mode while part of a Dell PowerConnect W AP Group set to
ap-mode
 Controller-level Spectrum Overrides (an alternative to creating new Dell PowerConnect W AP groups or new
radio profiles for temporary changes)
Setting up a Permanent Spectrum Dell AP Group
If you have multiple supported Dell PowerConnect W-Series APs in multiple controllers that you want to run in
Spectrum mode over the long run, you create a special Dell PowerConnect W AP group and set up a profile that
is set to spectrum-mode and references the default Spectrum profile. Set up more than one profile if you want to
utilize both radio bands in Spectrum mode.
If you use an 802.11a or 802.11g radio profile to create a group of spectrum monitors, all APs in any AP group
referencing that radio profile will be set to spectrum mode. Therefore, best practices are to create a new 802.11a
or 802.11g radio profile just for spectrum monitors.
If Use Global Dell PowerConnect W Configuration is enabled in AMP Setup > General, create the
configuration below, then go to the controller group's Dell PowerConnect W Config page and select the newly
created Dell PowerConnect W AP Group.
