Parameter Description
l 20: Select this option to disable 40 MHz mode and 80 Mhz mode and activate
20 MHz mode for the entered channel.
l 40: Entering a channel number and selecting the 40 radio button in the WebUI
selects a primary and secondary channel for 40 MHz mode. When you use this
option, the number entered becomes the primary channel and the secondary
channel is determined by increasing the primary channel number by 4. For
example, if you entered 157 into the Channel field and selected the above
option, radios using that profile would select 157 as the primary channel and
161 as the secondary channel.
l 80; Entering a channel number and selecting the 80 Mhz radio button selects a
primary and secondary channel for 80 MHz mode.
If you select the spectrum monitoring checkbox on this profile page, the AP will
operate as a hybrid AP and scan the selected channel for spectrum analysis data.
Non-Wi-Fi
Interference
Immunity
Set a value for non-Wi-Fi Interference Immunity.
The default setting for this parameter is level 2. When performance drops due to
interference from non-802.11 interferers (such as DECT or Bluetooth devices), the
level can be increased up to level 5 for improved performance. However,
increasing the level makes the AP slightly “deaf” to its surroundings, causing the AP
to lose a small amount of range.
The levels for this parameter are:
l Level 0: no ANI adaptation.
l Level 1: noise immunity only.
l Level 2: noise and spur immunity.
l Level 3: level 2 and weak OFDM immunity.
l Level 4: level 3 and FIR immunity.
l Level 5: disable PHY reporting.
NOTE: Only 802.11n-capable APs simultaneously support both the RX Sensitivity
Tuning Based Channel Reuse feature and a level-3 to level-5 Noise Immunity setting.
Do not raise the noise immunity default setting on APs that do not support 802.11n
unless you first disable the Channel Reuse feature.
Spectrum
Monitoring
Select this option to convert APs using this radio profile to a hybrid APs that will
continue to serve clients as an Access Point, but will also scan and analyze
spectrum analysis data for a single radio channel. For more details on hybrid APs,
see Spectrum Analysis on page 772.
Advanced 802.11a/802.11g Settings
Transmit EIRP Maximum transmit EIRP in dBm from 0 to 51 in .5 dBm increments, or 127 for
regulatory maximum. Transmit power may be further limited by regulatory domain
constraints and AP capabilities.
Enable CSA Channel Switch Announcements (CSAs), as defined by IEEE 802.11h, enable an AP
to announce that it is switching to a new channel before it begins transmitting on
that channel. This allows clients that support CSA to transition to the new channel
with minimal downtime.
