• 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.
