Setting up Dell Spectrum Analysis in AWMS
The spectrum analysis software modules on AP models Dell PowerConnect W-AP105, the Dell PowerConnect
W-AP120 Access Point Series and the Dell PowerConnect W-AP90 Access Point 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.
For more information about Spectrum analysis and ARM technology, refer to the ArubaOS 6.0 User Guide from

Spectrum Configurations and Prerequisites
The following prerequisites must be in place to configure an AP to run in spectrum mode in AWMS:
 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 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 AWMS:
 Dell PowerConnect W AP Groups running permanently with the default Spectrum profile
 Individual APs running temporarily in Spectrum mode while part of an Dell AP Group set to ap-mode
NOTE: The View AP Credentials message may appear slightly different depending on the vendor and model.
