Description
Select to increase the immunity level to improve performance in high-
interference environments.
The default immunity level is 2.
NOTE: Increasing the immunity level makes the AP slightly "deaf¨ to its
surroundings, causing the AP to lose a small amount of range.
Level 0: no ANI adaptation.

Level 1: Noise immunity only. This level enables power-based packet

detection by controlling the
 amount of power increase that makes a radio aware that it has
received a packet.
 Level 2: Noise and spur immunity. This level also controls the
detection of OFDM packets, and is the
 default setting for the Noise Immunity feature.
 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 2.4Ghz appliances such as
cordless phones.
 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.
 Level 5: The AP completely disables PHY error reporting, improving
performance by eliminating the time the 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, will automatically
adjust its Clear Channel Assessment (CCA) threshold to accommodate
transmissions to the most distant associated client.
When set to Static, the access point will set 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.
