DCS Update Period – Type the time, measured in minutes that
determines the period during which the Wireless AP averages the
DCS Noise Threshold and DCS Channel Occupancy Threshold
measurements. If either one of these thresholds is exceeded, then
the Wireless AP will trigger ACS.
10. In the Advanced dialog 11n Settings section, do the following:
Protection Mode – Click a protection mode: Enabled or Disabled. This
protects high throughput transmissions on primary channels from non-
11n APs and clients. Click Disabled if non-11n APs and clients are not
expected. Click Enabled if you expect many non-11n APs and clients.
The overall throughput is reduced when Protection Mode is enabled.
40MHz Protection Mode – Click a protection type, CTS Only or RTS-
CTS, or None, when a 40MHz channel is used. This protects high
throughput transmissions on extension channels from interference from
non-11n APs and clients.
40MHz Prot. Channel Offset – Select a 20MHz channel offset if the
deployment is using channels that are 20MHz apart (for example, using
channels 1, 5, 9, and 13) or a 25MHz channel offset if the deployment is
using channels that are 25MHz apart (for example, using channels 1, 6,
and 11).
40MHz Channel Busy Threshold – Type the extension channel
threshold percentage, which if exceeded, will disable transmissions on
the extension channel (40MHz).
Aggregate MSDUs Click an aggregate MSDU mode: Enabled or
Disabled. Aggregate MSDU increases the maximum frame transmission
size.
Aggregate MSDU Max Length – Type the maximum length of the
aggregate MSDU. The value range is 2290-4096 bytes.
Aggregate MPDUs Click an aggregate MPDU mode: Enabled or
Disabled. Aggregate MPDU provides a significant improvement in
throughput.
Aggregate MPDU Max Length – Type the maximum length of the
aggregate MPDU. The value range is 1024-65535 bytes.
Agg. MPDU Max # of Sub-frames – Type the maximum number of
sub-frames of the aggregate MPDU. The value range is 2-64.
ADDBA Support – Click an ADDBA support mode: Enabled or
Disabled. ADDBA, or block acknowledgement, provides
acknowledgement of a group of frames instead of a single frame.
ADDBA
Support must be enabled if Aggregate APDU is enable.
11. Click Close. The Advanced dialog is closed.
