Aggregation Length
(802.11ng and 802.11na/ac only)
Enter the maximum length of aggregated MAC protocol data unit
(AMPDU) packets.
Larger aggregation lengths could lead to better network performance.
Aggregation is a mechanism used to achieve higher throughput.
The default setting depends on the selection from the Wireless Mode
menu:
• If the selection from the Wireless Mode menu is 802.11ng or
802.11na, the default setting is 65535.
• If the selection from the Wireless Mode menu is 802.11na/ac, the
default setting is 1048575.
AMPDU
(802.11ng and 802.11na/ac only)
Select the enable radio button to allow the aggregation of several MAC
frames into a single large frame to achieve higher throughput. Enabled
is the default setting.
Enabling AMPDU could lead to better network performance. Select the
disable radio button to disable this option.
RIFS Transmission
(802.11ng and 802.11na/ac only)
Select the enable radio button to enable the reduced interframe space
(RIFS) option to allow transmission of successive frames at different
transmit powers.
Enabling RIFS could lead to better network performance. Select the
disable radio button to disable this option. Disabled is the default
setting.
DTIM Interval (1-255) Enter the delivery traffic indication message (DTIM) or the data beacon
rate that you want to use.
The message period of the beacon delivery traffic indication is set in
multiples of beacon intervals.
Preamble Type Select one of the following radio buttons to specify the preamble type:
• Auto. Automatically handles both long and short preambles. A
short transmit preamble provides better performance. Auto is the
default setting.
• Long. Enables a long transmit preamble to provide a more reliable
connection or a slightly longer range.
High Density Bandwidth
(802.11ng and 802.11na/ac only)
Select the bandwidth type:
• Auto. Automatically handles both high-density bandwidth (that is,
high throughput) and low-density bandwidth (that is, extended
range) environments. Auto is the default setting.
• High. Enables a high bandwidth setting for dense environments in
which multiple clients in a relatively small space require high
bandwidth. One example of such an environment is a classroom in
which multiple students stream video on individual WiFi devices.
• Low. Enables a low bandwidth setting for sparse environments in
which multiple clients are spread out over a relatively large space
and do not require high bandwidth. One example of such an
environment is a large office floor with multiple workers who do not
all access the Internet or intranet simultaneously.
