3. Click the Radio tab.
4. Under the channel 2.4.GHz or 5GHz or both, configure the following parameters.
Parameter Description
Legacy only Select Enabled to run the radio in non-802.11n mode. This option is set to Disabled
by default.
802.11d /
802.11h
Select Enabled to allow the radio to advertise its 802.11d (Country Information) and
802.11h (Transmit Power Control) capabilities. This option is set to Disabled by
default.
Beacon interval Enter the Beacon period for the IAP in milliseconds. This indicates how often the
802.11 beacon management frames are transmitted by the access point. You can
specify a value within the range of 60-500. The default value is 100 milliseconds.
Interference
immunity level
Select to increase the immunity level to improve performance in high-interference
environments.
The default immunity level is 2.
l Level 0— no ANI adaptation.
l 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.
l 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.
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 IAP would spend on PHY processing.
NOTE: Increasing the immunity level makes the AP to lose a small amount of range.
Channel switch
announcement
count
Specify the count to indicate the number of channel switching announcements that
must be sent before switching to a new channel. This allows associated clients to
recover gracefully from a channel change.
Background
spectrum
monitoring
Select Enabled to allow the APs in access mode to continue with normal access
service to clients, while performing additional function of monitoring RF interference
(from both neighboring APs and non Wi-Fi sources such as, microwaves and
cordless phones) on the channel they are currently serving clients.
