Override Channel and Transmission Power in an Advanced
Profile Group
The table on the Advanced Wireless Settings screen shows the access points that are
managed in the profiles of an advanced profile group and to which the channel allocation and
advanced RF management settings apply.
After you have configured the wireless settings for an advanced profile group (see the
previous section), you can change the channel, the transmission power, or both for individual
access points in an advanced profile group.
Fragmentation Length (256-2346) Enter the size that specifies the maximum fragmentation length for data
packets.
Packets larger than the specified fragmentation length are broken up
into smaller packets before being transmitted.
The fragmentation length
needs to be an even number
.
Beacon Interval (100-1000) Enter the time interval for each beacon transmission that allows the
access point to synchronize the wireless network.
Aggregation Length (1024-65535)
(802.11n only)
Enter the maximum length of aggregated MAC protocol data unit
(AMPDU) packets.
Larger aggregation lengths can lead to better network performance.
Aggregation is a mechanism used to achieve higher throughput.
AMPDU
(802.11n only)
Select the On radio button to allow the aggregation of several MAC
frames into a single large frame to achieve higher throughput.
Enabling AMPDU can lead to better network performance. Select the
Off radio button to disable this option.
RIFS Transmission
(802.11n only)
Select the On radio button to enable the reduced interframe space
(RIFS) option to allow transmission of successive frames at dif
ferent
transmit powers.
Enabling RIFS can lead to better network performance. Select the
Off
radio button to disable this option.
DTIM Interval (1-255) Enter the delivery traffic indication message (DTIM) or the data beacon
rate that you want to use.
This sets the message period of the beacon delivery traffic indication in
multiples of beacon intervals.
Preamble Type
(802.11b/bg only)
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.
