TRENDnet User's Guide
Band Mode : Select an appropriate wireless band; bands available are 801.11a or
802.11a/n mixed mode.
Transmit Rate Control : Select the desired rate from the drop-down list; the options
are auto or ranging from 6 to 54 Mbps for 802.11a
Tx Power : You can adjust the output power of the system to get the appropriate
coverage for your wireless network. Specify digit number between 1 to 100 (the
unit is %) for your environment. If you are not sure of which setting to choose, then
keep the default setting, 100%.
When Band Mode select in 802.11a only mode, the HT(High Throughput) Physical
Mode and 11n Configuration settings should be hidden immediately.
Operating Mode : By default, it's Mixed Mode
Mixed Mode : In this mode packets are transmitted with a preamble
compatible with the legacy 802.11a/g, the rest of the packet has a new format.
In this mode the receiver shall be able to decode both the Mixed Mode
packets and legacy packets.
Green Field : In this mode high throughput packets are transmitted without a
legacy compatible part.
Channel Bandwidth : The "Auto" MHz option is usually best. The other option is
available for special circumstances.
Guard Interval : Using "Auto" option can increase throughput. However, it can also
increase error rate in some installations, due to increased sensitivity to radio-
frequency reflections. Select the option that works best for your installation.
MCS : This parameter represents transmission rate. By default (Auto) the fastest
possible transmission rate will be selected. You have the option of selecting the
speed if necessary. (Refer to Appendix C. MCS Data Rate)
MPDU Enable : Check Enable button to activate this function, and Disable to
deactivate.
A-MPDU : A-MPDU (Aggregated Mac Protocol Data Unit) allows the transmissions
of multiple Ethernet frames to a single location as burst of up to 64kbytes This is
performed on the hardware itself. Select "Manual" to set "MPDU Density"
MPDU Density : Minimum separation of MPDUs in an A-MPDU.

A-MSDU : Aggregated Mac Service Data Unit, A-MSDU. Select Enable to allow
aggregation for multiple MSDUs in one MPDU. Default is disabled.

Wireless Advanced Setup
To achieve optimal wireless performance, it is necessary to tweak advance setting per
requirements properly, not necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings
for the system. Please click on Wireless -> Advanced Setup and follow the below setting.
Short Slot : By default, it's "Enable" for educing the slot time from the standard 20
microseconds to the 9 microsecond short slot time
Slot time is the amount of time a device waits after a collision before retransmitting
a packet. Reducing the slot time decreases the overall back-off, which increases
throughput. Back-off, which is a multiple of the slot time, is the random length of
time a station waits before sending a packet on the LAN. For a sender and receiver
own right of the channel the shorter slot time help manage shorter wait time to re-
transmit from collision because of hidden wireless clients or other causes. When
collision sources can be removed sooner and other senders attempting to send are
listening the channel(CSMA/CA) the owner of the channel should continue
