LABEL	DESCRIPTION
RTS/CTS	Data with its frame size larger than this value will perform the RTS (Request To
Threshold	Send)/CTS (Clear To Send) handshake.
	Enter a value between 256 and 2432.
Fragmentation	The threshold (number of bytes) for the fragmentation boundary for directed
Threshold	messages. It is the maximum data fragment size that can be sent. Enter an even
	number between 256 and 2346.
Output Power	Set the output power of the NBG4615 in this field. If there is a high density of APs
	in an area, decrease the output power of the NBG4615 to reduce interference with
	other APs. Select one of the following 100%, 90%, 75%, 50%, 25% or 10%.
	See the product specifications for more information on your NBG4615’s output
	power.

HT (High Throughput) Physical Mode - Use the fields below to configure the 802.11 wireless environment of your NBG4615.

Operating Mode	Choose this according to the wireless mode(s) used in your network.
	Mixed - Select this if the wireless clients in your network use different wireless
	modes (for example, IEEE 802.11b/g and IEEE 802.1n modes)
	Green - Select this if the wireless clients in your network uses only one type of
	wireless mode (for example, IEEEE 802.11 n only)
Channel	Select the channel bandwidth you want to use for your wireless network.
Bandwidth	It is recommended that you select 20/40 (20/40 MHz).
	Select 20 MHz if you want to lessen radio interference with other wireless devices
	in your neighborhood.
