Parameter Description
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 733.
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
W-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:
l 0: default CPT
l 1-19: CPT growth from default (3 dBm to 21 dB)
l 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 Dell Technical Support.
NOTE: Setting the spur immunity to a higher value may decrease the AP RF
coverage.
NOTE: This parameter is applicable for W-AP130 Series access points only. The
controller ignores this parameter if configured for non-W-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.
