V2.0
A part of the 802.11n standard (or draft-standard). It allows sending multiple frames per single
access to the medium by combining frames together into one larger frame. It creates the larger
frame by combining smaller frames with the same physical source and destination end poi
nts and
traffic class (i.e. QoS) into one large frame with a common MAC header.

Advanced Setup
Beacon Interval:
Beacon Interval is in the range of
40
~
3500
and set in unit of
millisecond
. The
default value is
100
msec.
Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte frame, called
“Beacon”. Beacon is broadcast to all the stations, provides the basic information of AP such as
SSID, channel, encryption keys, signal strength, time stamp, support data rate.
All the radio stations received beacon recognizes the existence of such AP, and may proceed
next actions if the information from AP matches the requirement. Beacon is sent on a periodic
basis, the time interval can be adjusted.
By increasing the beacon interval, you can reduce the number of beacons and associated
overhead, but that will likely delay the association and roaming process because stations
scanning for available access points may miss the beacons. You can decrease the beacon
interval, which increases the rate of beacons. This will make the association and roaming
process very responsive; however, the network will incur additional overhead and throughput
will go down.
DTIM Interval:
The DTIM interval is in the range of
1
~
255
. The default is
1
.
DTIM is defined as
Delivery Traffic Indication Message
. It is used to notify the wireless stations,
