Parameter Description
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:
n Level 0: no ANI adaptation.
n Level 1: noise immunity only.
n Level 2: noise and spur immunity.
n Level 3: level 2 and weak OFDM immunity.
n Level 4: level 3 and FIR immunity.
n 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 749.
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.
Spur Immunity Spur Immunity for 5 GHz radio. This parameter fine-tunes the Cyclic Power Threshold
(CPT) of a 5 GHz radio. The value specified here is the offset from the base value of 2
dB (for example, setting the CPT value to 1 corresponds to 2 + 1 = 3 dB. Similarly,
setting the CPT value to 10 corresponds to 2+10 = 12 dB).
Use this parameter when high channel utilization is observed in the 5 GHz radio of
OAW-AP130 Series access points in a noise-free environment causing client
association or throughput issues.
Adjust the CPT value to eliminate the spur impacts. Range definition is as follows:
n 0: default CPT
n 1-19: CPT growth from default (3 dBm to 21 dB)
n 20: Setting this parameter to 20 sets the cell-size-reduction value to 1. Cell-size-
reduction is the receive coverage area of the AP.
NOTE: Configure this parameter under the supervision of Alcatel-Lucent Technical
Support.
NOTE: Setting the spur immunity to a higher value may decrease the AP RF coverage.
NOTE: This parameter is applicable for OAW-AP130 Series access points only. The
switch ignores this parameter if configured for non-OAW-AP130 Series access points.
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.
