Description
The Transmit Rate field allows to define the data transfer rate. The
default value if Fully Automatic. In this case, the best transfer rate is
negotiated between this wireless node and access point or another
wireless note that it is communicating with. Other option values for
this field are 1, 2, 5.5 and 11 Mbps.
Power saving options are Off, Normal, and Maximum. Power saving is
disable when Ad-Hoc mode is selected in the Network Mode field.
When the Power Saving setting is Off, the adapter receives full power
from the PC. When the setting is Normal, the driver turns off power to
the MA521 Wireless PC Card for brief periods over briefly-spaced time
intervals. When the setting is Maximum, the driver turns off power to
the MA521 Wireless PC Card for longer periods over more widely-
spaced time intervals.
This option controls the Radio Frequency (RF) output power. Selects
100%, 50%, 25%, 12.5%, or Minimum.
A long transmit preamble allows the receiver (MA521 Wireless PC Card)
to lock into the received bit patterns more easily. A short transmit
preamble provides better performance. Default: Auto (long & short).
This is the packet length used for fragmentation. Packets larger than
the size programmed in this field will be fragmented. The
Fragmentation Threshold value must be larger than RTS Threshold
value. The default value for Fragmentation Threshold is 2432.
The packet size that wireless node uses to determine if it should use the
CDMA/CD mechanism or the CSMA/CA mechanism for packet
transmission. With the CSMA/CD transmission mechanism, the
transmitting station sends out the actual packet as soon as it has waited
for the silence period. With the CSMA/CA transmission mechanism, the
transmitting station sends out a RTS packet to the receiving station,
waits for the receiving station to send back a CTS packet before sending
the actual packet data. The default value for RTS Threshold is 2432.
