Parameter Description
Channel Transmit channel for this radio. The available channels depend on the regulatory
domain (country). This parameter includes the following channel number
configuration options for 20 MHz, 40 MHz and 80 MHz modes:
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 700.
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.
CSA Count Number of channel switch announcements that must be sent prior to switching to a
new channel. The default CSA count is 4 announcements.
Advertise 802.11d
and 802.11h
Capabilities
Enable the radio to advertise its 802.11d (Country Information) and 802.11h
(Transmit Power Control) capabilities. This option is disabled by default.
