Parameter Description
Management
Frame Throttle
Interval
Averaging interval for rate limiting management frames from this radio, in
seconds. A management frame throttle interval of 0 seconds disables rate limiting.
Management
Frame Throttle
Limit
Maximum number of management frames that can come in from this radio in each
throttle interval.
Maximum Distance Maximum client distance, in meters. This value is used to derive ACK and CTS
timeout times. A value of 0 specifies default settings for this parameter, where
timeouts are only modified for outdoor mesh radios which use a distance of 16km.
The upper limit for this parameter varies from 24km–58km, depending on the
radio’s band (a/g) and 20/40 MHz mode. Note that if you configure a value above
the supported maximum, the maximum supported value will be used instead.
Values below 600m will use default settings.
RX Sensitivity
Tuning Based
Channel Reuse
In some dense deployments, it is possible for APs to hear other APs on the same
channel. This creates co-channel interference and reduces the overall utilization of
the channel in a given area. Channel reuse enables dynamic control over the
receive (Rx) sensitivity in order to improve spatial reuse of the channel.
This feature is disabled by default. To enable this feature, click the RX Sensitivity
Tuning Based Channel Reuse drop-down list and select either static or
dynamic.To disable this feature, click the RX Sensitivity Tuning Based Channel
Reuse drop-down list and select disable. For details on each of these modes, see
Reusing Channels to Control RX Sensitivity Tuning on page 529.
NOTE: Do not enable the Channel Reuse feature if Non-Wi-Fi Interference Immunity
on page 596 is set to level 3 or higher. A level-3 to level-4 Noise Immunity setting is
not compatible with the Channel Reuse feature. The channel reuse feature applies
to non-DFS channels only. It is internally disabled for DFS channels and is does not
affect DFS radar signature detection.
RX Sensitivity
Threshold
RX sensitivity tuning based channel reuse threshold, in - dBm.
If the Rx Sensitivity Tuning Based Channel reuse feature is set to static mode, this
parameter manually sets the AP’s Rx sensitivity threshold
(in -dBm). The AP will filter out and ignore weak signals that are below the channel
threshold signal strength.
If the value for this parameter is set to zero, the feature will automatically
determine an appropriate threshold.
Protection for
802.11b Clients
(For 802.11g RF Management Profiles only) Enable or disable protection for
802.11b clients. This parameter is enabled by default. Disabling this feature may
improve performance if there are no 802.11b clients on the WLAN.
WARNING: Disabling protection violates the 802.11 standard and may cause
interoperability issues. If this feature is disabled on a WLAN with 802.11b clients,
the 802.11b clients will not detect an 802.11g client talking and can potentially
transmit at the same time, thus garbling both frames.
Associated Profiles
ARM profile Dell's proprietary Adaptive Radio Management (ARM) technology maximizes
WLAN performance by dynamically and intelligently choosing the best 802.11
channel and transmit power for each Dell AP in its current RF environment.
