Configuring Radio Settings
You can configure 2.4 GHz and 5 GHz radio settings for an AP either using the SCALANCE
W UI or the CLI.
In the SCALANCE W UI
To configure radio settings:
1.
Click the RF link located directly above the Search bar of the SCALANCE W main
window.
2.
Click Show advanced options. The advanced options are displayed.
3.
Click the Radio tab.
4.
Under the channel 2.4.GHz or 5 GHz, 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 AP 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.
•
Level 0—no ANI adaptation.
•
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.
•
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.
•
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.
•
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.
•
Level 5—The AP completely disables PHY error reporting,
improving performance by eliminating the time the AP would
spend on PHY processing.
NOTE: Increasing the immunity level makes the AP to lose a small
amount of range.
