DTIM (Delivery Traffic Indication
Map)
This is the Delivery Traffic Indication Map. It is used to alert the clients that
multicast and broadcast packets buffered at the AP will be transmitted
immediately after the transmission of this beacon frame. You can change
the value from 1 to 255. The AP will check the buffered data according to
this value. For example, selecting “1” means to check the buffered data at
every beacon.
Fragment Size
A large data frame is fragmented into several fragments each of size equal
to fragment threshold. By tuning the fragment threshold value, we can get
varying fragment sizes.
Short GI (Guard Interval)
A GI is a period of time between symbol transmission that allows
reflections (from multipath) from the previous data transmission to settle
before transmitting a new symbol. The 802.11n draft specifies two guard
intervals: 400ns (short) and 800ns (long). Support of the 400ns GI is
optional for transmit and receive. The purpose of a guard interval is to
introduce immunity to propagation delays, echoes, and reflections to
which digital data is normally very sensitive.
Aggregation
A part of the 802.11n standard that 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, destination end points, and traffic class (QoS) into
one large frame with a common MAC header
Aggregated Frames Number
Determines the number of frames combined in the new larger frame.
Maximum Aggregated Size
Determines the size (in bytes) of the larger frame.
Tx/Rx ChainMask
Displays the number of independent spatial data streams the device is
transmitting (TX) and receiving (RX) simultaneously within one spectral
channel of bandwidth. Multiple chains increase data transfer performance
significantly

WMM Configuration
Displays the WMM Parameters of station and Access Point

Access Control
This page allows administrator to have Access Control by entering MAC address of client
stations. When this function is Enabled, MAC address can be added into access control list and
only those clients whose wireless MAC address are in the access control list will be able to
connect or disconnect the internet.
