intolerance of 40 MHz operation. (This option is disabled by default, allowing 40 MHz operation.) Refer to
“Profiles > RF > 802.11a/g Radio > HT Radio” on page 116.
Spectrum—Defines AP radio settings for spectrum analysis on specific Dell PowerConnect W AP models that
can examine the RF environment in which the Wi-Fi network is operating, identify interference, and classify
its sources. Refer to “Profiles > RF > 802.11a/g Radio > Spectrum” on page117.
Event Thresholds—Defines error event conditions, based on a customizable percentage of low-speed frames,
non-unicast frames, or fragmented, retry or error frames. “Profiles > RF > Event Thresholds” on page 118
Optimization—Enables or disables load balancing based on a user-defined number of clients or degree of AP
utilization on an AP. Use this profile to detect coverage holes, radio interference and STA association failures
and configure Received signal strength indication (RSSI) metrics. “Profiles > RF > Optimization” on
page 120

The two 802.11a and 802.11g RF management profiles for an AP configure its 802.11a (5 GHz) and 802.11b/g
(2.4 GHz) radio settings. Use these profile settings to determine the channel, beacon period, transmit power, and
ARM profile for a mesh AP’s 5 GHz and 2.5 GHz frequency bands. You can either use the “default” version of
each profile, or create a new 802.11a or 802.11g profile which you can then configure as necessary. Each RF
management profile also has a radio-enable parameter that allows you to enable or disable the AP’s ability to
simultaneously carry WLAN client traffic and mesh-backhaul traffic on that radio.
Radios are enabled by default.
Perform these steps to create or edit radio profiles for 802.11a or g. This type of radio profile references additional
profiles such as ARM and High-throughput Radio profiles. You have the chance to add or edit supporting profiles
as you define 802.11a/g Radio profiles.
1. Select Profiles > RF > 802.11a/g in the Dell PowerConnect W Configuration navigation pane.
2. Select the appropriate Add button to create a new 802.11a or g profile, or click the pencil icon to edit an
existing profile. Complete the settings as described in Table 51:

Profile
Default Select an ARM profile from the drop-down menu to define ARM settings for your 802.11a/g
radio profile. Select the pencil icon to edit an existing ARM profile, or click the plus sign to
create a new ARM profile. You are directed to the ARM Profile setup page. Once you have
configured this referenced ARM profile, AirWave returns you to the 802.11a/g radio profile
page.
For additional ARM profile information, refer to “Profiles > RF > 802.11a/g Radio > ARM” on
page 113.
Spectrum Profile Select a profile to define settings for Spectrum scanning. Select the pencil icon to edit an
existing Spectrum profile, or click the plus sign to create a new AM Scanning profile. You
are directed to the Spectrum Profile setup page.
NOTE: AMP displays an error message if you try to select an incompatible spectrum profile.
A '2ghz' spectrum band profile cannot be referenced by an '802.11a' profile and vice-versa.
