Parameter Channel switch announcement count Channel reuse type Channel reuse threshold Background spectrum monitoring Standalone spectrum band Description l Level 0- no ANI adaptation. l Level 1- Noise immunity only. This level enables power-based packet detection by controlling the l amount of power increase that makes a radio aware that it has received a packet. l Level 2- Noise and spur immunity. This level also controls the detection of OFDM packets, and is the l default setting for the Noise Immunity feature. l Level 3- Level 2 settings and weak OFDM immunity. This level minimizes false detects on the radio due to interference, but may also reduce radio sensitivity. This level is recommended for environments with a high-level of interference related to 2.4 GHz appliances such as cordless phones. l Level 4- Level 3 settings, and FIR immunity. At this level, the AP adjusts its sensitivity to in-band power, which can improve performance in environments with high and constant levels of noise interference. l Level 5- The AP completely disables PHY error reporting, improving performance by eliminating the time the W-IAP would spend on PHY processing. Indicates the number of channel switching announcements that must be sent prior to switching to a new channel. This allows associated clients to recover gracefully from a channel change. When set to Dynamic, the access point, when busy, automatically adjust its Clear Channel Assessment (CCA) threshold to accommodate transmissions to the most distant associated client. When set to Static, the access point sets its CCA threshold to the value specified in Channel reuse threshold. When set to Static, this value specifies the tolerable interference that must be maintained. When background spectrum monitoring is enabled, the APs in access mode continue to provide normal access service to clients, while performing additional function of monitoring RF interference (from both neigh bo uri ng APs and non Wi-Fi sources such as, microwaves and cordless phones) on the channel they are currently serving clients on. For background spectrum monitoring on the 5 GHz band, it is necessary to specify which portion of the channel to monitor: upper, middle, or lower. NOTE: Reboot the W-IAP after configuring the radio profile settings in order for the changes to take effect.

Channel switch announcement
count
Indicates the number of channel switching
announcements that must be sent prior to switching
to a new channel. This allows associated clients to
recover gracefully from a channel change.
Channel reuse type
When set to
Dynamic
, the access point, when busy,
automatically adjust its Clear Channel Assessment
(CCA) threshold to accommodate transmissions to
the most distant associated client.
When set to
Static
, the access point sets its CCA
threshold to the value specified in
Channel reuse
threshold
.
Channel reuse threshold
When set to
Static,
this value specifies the tolerable
interference that must be maintained.
Background spectrum
monitoring
When background spectrum monitoring is enabled,
the APs in access mode continue to provide normal
access service to clients, while performing
additional function of monitoring RF interference
(from both neigh bo uri ng APs and non Wi-Fi
sources such as, microwaves and cordless phones)
on the channel they are currently serving clients on.
Standalone spectrum band
For background spectrum monitoring on the 5 GHz
band, it is necessary to specify which portion of the
channel to monitor: upper, middle, or lower.
NOTE: Reboot the W-IAP after configuring the radio profile settings in order for the changes
to take effect.
