40MHz Channel Busy Threshold Type the extension channel threshold percentage, which if

exceeded, will disable transmissions on the extension channel

(40MHz).

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).

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 APDU is enable.

LDPC 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.

STBC Click an STBC mode: Enabled or Disabled. STBC is a simple

open loop transmit diversity scheme. When enabled, STBC

configuration is 2x1 (one spatial stream split into two space-time

streams). TXBF will override STBC if both are enabled for single

stream rates.

TXBF Click an TXBF mode: Enabled or Disabled. Tx Beam Forming

focuses transmission beams directly at the intended receiver while

reducing the overall interference generated by the transmitter.

Advanced Dialog - 11b Settings

Preamble Click a preamble type for 11b-specific (CCK) rates: Short or

Long. Click Short if you are sure that there is no pre-11b AP or a

client in the vicinity of this Wireless 802.11n AP. Click Long if

compatibility with pre-11b clients is required.

Advanced Dialog - 11g Settings

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 Rate Click a protection rate: 1, 2, 5.5, or 11 Mbps. The default and

recommended setting is 11. Only reduce the rate if there are many

11b clients in the environment or if the deployment has areas with

poor coverage. For example, rates lower than 11 Mbps are

required to ensure coverage.
