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.

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.
