Parameter Description
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 449.
NOTE: Do not enable the Channel Reuse feature if Non-Wi-Fi Interference Immunity
on page 512 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.
Every RF management profile references an ARM profile. If you specify an active and
enabled ARM profile, you do not need to manually configure the Channel and
Transmit Power parameters for this 802.11a or 802.11g profile. For details on
referencing an ARM profile, see Assigning an ARM Profile on page 516.
The Adaptive Radio Management (ARM) profile associated with this 802.11a or
802.11g radio profile appears beneath the 802.11a/802.11g radio profile name in
the profiles list. To change the ARM profile associated with an 802.11a or 802.11g
radio profile, select the associated ARM profile in the profiles list then click the drop-
down list in the Profile Details section of the page to select a new profile.
