is ‘auto’.
8. PREAMBLE:
This function determines the PREAMBLE TYPE that physical layer’s PLCP will use. There are
three modes to choose: LONG, SHORT, and AUTO. The default setting is AUTO, and the system
will automatically choose the optimized mode.
9. Tx Power Level (mW): Does not open to change.
10. Fragmentation Threshold:
This configuration determines whether needs to fragment the Frame during transmit. When
fragment, if the transmit fell, computer only resent the fell frame instead of the whole file again.
When the frequency band used is not clear, i.e. The S/N ratio is low, transmit is easier to fell. Under
this situation, fragmentation is a good way to increase efficiency.
11. RTS/CTS:
When frame smaller than the RTS Threshold value, the STA will automatically transmit the frame
if the channel is available. If the channel is used, STA will follow the 802.11b regulation that would
ask the receiving device whether to send the frame. This will take more time for devices to check
with each other, but it also prevents the loss of frames.
12. Power Save:
Determine whether to use power saving mode. The default setting is ‘Disable’.
