Use Aggregation
This option defines whether or not the
Media Access Control (MAC) layer will set up an Add Block
Acknowledgement (ADDBA) session. The default is Yes.
Select No to disable this option.
Accept Aggregation
This option defines whether or not
the MAC layer will accept an ADDBA request. The default
is Yes. Select No to disable this option.
Max. Number of Packets in Aggregation
defines the maximum number of packets (sub-frames) in
the aggregate. The range is 0 to 2. The default is 2.
Max. Aggregation Size
This option defines the maximum
size of the aggregate (in bytes). The range is 0 to 16000.
The default is 10000.
Timeout Internal
This option defines the timeout period
in which the aggregate should be closed with a "closing
condition" before it is closed by the timer. The range is 0 to
100 ms. The default is 10.
Min. Size of Packet in Aggregation
the minimum size (in bytes) of packets to be accumulated
in the aggregate. The range is 0 to 1500. The default
is 10.
ADDBA Timeout
This option defines the duration
after which the ADDBA setup is terminated, if there are
no frame exchanges within this duration by the Block
Acknowledgement (ACK) agreement. The range is 0 to
65535 ms. The default is 0, which disables the timeout.
Aggregation Window Size
maximum number of packets transmitted without getting
ACKs. The range is 0 to 64. The default is 64.

Advanced Wireless
Use LDPC
Low-Density Parity-Check Code (LDPC) enables
or disables error correction to reduce the probability of
data loss in noisy channels. The Rate Adaptation algorithm
automatically disabled LDPC coding when working at high
PHY rates (higher than 162). To use the LDCP advanced
error correction scheme, keep the default, Yes. Otherwise,
select No.
ERP Protection Type
This option configures protection
of OFDM packets despite the presence of 802.11b stations
within the wireless network. By sending RTS/CTS or
CTS2Self packets in 802.11b rates, the Bridge informs
the wireless network that OFDM packets are going to
be transferred and protects the packets in the wireless
network. The RTS/CTS and CTS2Self packets create
overhead, which may result in lower throughputs.
The RTS/CTS option provides better coverage but lower
throughputs when compared to CTS2Self, because the
RTS/CTS option includes acknowledgement from the
receiving device. To use the RTS/CTS option, keep the
default, RTS/CTS. The None option may cause collisions
between OFDM and CCK packets. To use the None option,
select None. To use the CTS2Self option, select CTS2Self.
11n Protection Type
This option configures protection
from non-High Throughput (HT) devices within the
wireless network. In case the wireless router (or access
point) detects an association of a non-HT legacy device,
it will signal all the HT devices to use RTS/CTS or CTS2Self
mechanisms before each data transmission. This feature
also supports all 802.11n standard protections, including
MIMO.
The RTS/CTS option provides better coverage but lower
throughputs when compared to CTS2Self, because the
RTS/CTS option includes acknowledgement from the
receiving device. To use the RTS/CTS option, keep the
default, RTS/CTS. The None option may cause collisions
between HT and legacy packets. To use the None option,
select None. To use the CTS2Self option, select CTS2Self.
Percentage of maximal transmit power
sets the percentage of maximal transmit power relative
to the regulatory domain restrictions. For example, if the
regulatory domain restriction allows transmissions of
up to 20 dB, then setting the percentage at 50% allows
maximal transmit power of 10 dB. Select the percentage
you want to use: 12%, 25%, 50%, or 100%. The default
is 100%.
QoS Classification Type
This option sets 802.1D or
802.1Q mapping from the IP DSCP/TOS field to WMM
priorities (Background, Best Effects, Video, Voice). Keep
