Description
channel is determined by decreasing the
primary channel number by 4. Example: 157-
represents 157 as the primary channel and 153
as the secondary channel.
NOTE: 20 MHz clients are allowed to associate
when a primary and secondary channel are
configured; however, the client will only use the
primary channel.
When you enable the channel reuse feature, it can
operate in either of the following three modes;
static, dynamic or disable. (This feature is disabled
by default.)
Static mode: This mode of operation is a
l
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 mode: In this mode, the Clear
l
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 mode: This mode does not support the
l
tuning of the CCA Detect 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 is set to zero, the feature will
automatically determine an appropriate threshold.
Name of an existing radio profile from which
parameter values are copied.
Channel Switch Announcement (CSA), as defined
by IEEE 802.11h, allows an AP to announce that it is
switching to a new channel before it begins
transmitting on that channel.
Clients must support CSA in order to track the
channel change without experiencing disruption.
Number of CSA announcements that are sent
before the AP begins transmitting on the new
channel.
