Lucent Technologies GW-DS300N manual Basic Installation & Configuration

	can select a channel for GW-DS300N. If enabling	2
	this mode, the PSM mode will NOT take effect and
	the Preamble function will be enabled.
TX Power	Choose the TX (transmission) Power according to
	the real environment. If you want to lower the
	transmit power of the adapter for saving the
	power of the system, you can select the lower
	percentages from the list. The lower power
	will cause the lower signal strength and the
	coverage range. The default setting is “Auto”.
Preamble	The preamble defines the length of the CRC (cyclic
	redundancy check) block when communicating
	among the wireless networks. There are two types
	of preamble: Auto and Long Preamble. Intensive
	network traffic areas should use the short preamble
	type.
RTS Threshold	Here it defines the minimum packet size required for
	RTS (Request to Send). Select a value within a range
	of 0 to 2347 bytes. Normally, if there are no hiding
	nodes problems, the values no need to be altered.
Fragment Threshold	The value defines the maximum size of packets; any
	packet size larger than the value will be fragmented.

If you have decreased this value and experience higher packet error rates, you can increase the value again, but it will likely decrease the overall network performance. Select a value within the range of 256 to 2346 bytes. The default value is 2346.
