Video VI For each radio, click the number of retries for the Video
transmission queue. The default value is adaptive (multi-rate).
The recommended setting is adaptive (multi-rate).
Voice VO For each radio, click the number of retries for the Voice
transmission queue. The default value is adaptive (multi-rate).
The recommended setting is adaptive (multi-rate).
Turbo Voice TVO For each radio, click the number of retries for the Turbo Voice
transmission queue. The default value is adaptive (multi-rate).
The recommended setting is adaptive (multi-rate).

Protection Mode Click a protection mode: None, Auto, or Always. The default and
recommended setting is Auto. Click None if 11b APs and clients
are not expected. Click Always if you expect many 11b-only
clients.
Protection Type Click a protection type, CTS Only or RTS- CTS, 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 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 MPDU is enable.
LDPC
(Available for W78xC APs.)
Click an LDPC mode: Enabled or Disabled. LDPC increases the
reliability of the transmission resulting in a 2dB increased
performance compared to traditional 11n coding.
