General Specifications	Model MA401 Wireless PC Card

Authentication Algorithm	Open System: No secret key is shared between the sender and recipient.
	Each party generates its own key and asks the receiver to
	accept the key.
	Shared Key: Both sender and recipient share a secret key.

Fragmentation Threshold	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.

Power save mode	Power saving mode. This enables the wireless node to control its wireless
	power consumption. The default setting for Power Save mode is Disabled.

Preamble Mode	A long transmit preamble allows the receiver to lock into the received bit
	patterns more easily. A short transmit preamble provides better
	performance. The default value is Long Tx Preamble.

RTS Threshold	The packet size that the wireless node uses to determine if it should use
	the CSMA/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.
