Advertise 802.11d and 802.11h
Capabilities
If enabled, the radio advertises its 802.11d (Country Information) and 802.11h (Transmit
Power Control) capabilities.
TPC Power The transmit power advertised in the TPC IE of beacons and probe responses
Spectrum load balancing The Spectrum load balancing feature helps optimize network resources by balancing
clients across channels, regardless of whether the AP or the controller is responding to
the wireless clients' probe requests.
If enabled, the controller compares whether or not an AP has more clients than its
neighboring APs on other channels. If an AP’s client load is at or over a predetermined
threshold as compared to its immediate neighbors, or if a neighboring Dell AP on another
channel does not have any clients, load balancing is enabled on that AP. This feature is
disabled by default.
Spectrum load balancing mode SLB Mode allows control over how to balance clients. Channel-based load-balancing
balances clients across channels. Radio-based load-balancing distributes clients across
radios on the same band, independent of channels.
Spectrum load balancing mode
update interval
This parameter specifies how often spectrum load balancing calculations are made (in
seconds). The default value is 30 seconds.
Spectrum load balancing threshold If the spectrum load balancing feature is enabled, this parameter ontrols the percentage
difference between number of clients on a channel channel that triggers load balancing.
The default value is 20%, meaning that spectrum load balancing is activated when there
are 20% more clients on one channel than on another channel used by the AP radio.
Advertised Regulatory Max EIRP Shows if the radio is configured to work around a known issue on Cisco 7921G telephones
by capping for a radio’s maximum equivalent isotropic radiated power (EIRP). When you
enable this parameter, even if the regulatory approved maximum for a given channel is
higher than this EIRP cap, the AP radio using this profile will advertise only this capped
maximum EIRP in its radio beacons.
The supported value is1–31 dBm.
Spectrum load balancing domain Define a spectrum load balancing domain to manually create RF neighborhoods.
Use this option to create RF neighborhood information for networks that have disabled
Adaptive Radio Management (ARM) scanning and channel assignment.
 If spectrum load balancing is enabled in a 802.11g radio profile but the spectrum load
balancing domain is not defined, ArubaOS uses the ARM feature to calculate RF
neighborhoods.
 If spectrum load balancing is enabled in a 802.11g radio profile and a spectrum load
balancing domain is also defined, AP radios belonging to the same spectrum load
balancing domain are considered part of the same RF neighborhood for load
balancing, and will not recognize RF neighborhoods defined by the ARM feature.
RX Sensitivity Tuning Based
Channel Reuse
Shows if the channel reuse feature’s current operating mode, static, dynamic or disable.
 Static: This mode of operation is a coverage-based adaptation of the Clear Channel
Assessment (CCA) thresholds. In the static mode of operation, the CCA is adjusted
according to the configured transmission power level on the AP, so as the AP transmit
power decreases as the CCA threshold increases, and vice versa.
 Dynamic: In this mode, the Clear Channel Assessment (CCA) thresholds are based on
channel loads, and take into account the location of the associated clients. When you
set the Channel Reuse This feature is automatically enabled when the wireless
medium around the AP is busy greater than half the time. When this mode is enabled,
the CCA threshold adjusts to accommodate transmissions between the AP its most
distant associated client.
 Disable: This mode does not support the tuning of the CCA Detect Threshold.
RX Sensitivity Threshold If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this
parameter manually sets the AP’s Rx sensitivity threshold (-dBm). The AP will filter out and
ignore weak signals that are below the channel threshold signal strength. For example, if
the RX sensitivity threshold was set to -65 dBm, the AP would ignore signals with a
strength from -1 dBM to -64 dBm. If the value is set to zero, the feature will automatically
determine an appropriate threshold.
