Description
Preamble Type
A preamble is a signal used in wireless
environment to synchronize the transmitting
timing including Synchronization and Start
frame delimiter. (Note: Checking the setting of
AP prior to changing the Preamble type is
recommended.)
?
Long
If in a "noisy" network environment, the
Preamble Type should be set to
Long
.
?
Short
The
Short
preamble is intended for applications
where
minimum
overhead
and
maximum
performance is desired. If in a "noisy" network
environment,
the
performance
would
be
decreased.
?
Auto
Select
Auto
for the USB adapter to select the
Preamble type automatically depending on the
Access Point Preamble type.
Fragmentation
Threshold
To fragment MSDU or MMPDU into small sizes
of frames for increasing the reliability of frame
(The maximum value of 2346 means no
fragmentation is needed) transmission. The
performance will be decreased as well, thus a
noisy environment is recommended.
RTS/CTS
Threshold
This value should remain at its default setting of
2347
.
Should you encounter inconsistent data
flow, only minor modifications of this value are
recommended.
Power Save
Check the box to allow the Adapter to go to
sleep mode, during which data communication
could be interrupted.
