NetComm NP5400 manual Ofdm, Ssid

mIRC	mIRC runs under Windows and provides a graphical
	interface for logging onto IRC servers and listing, joining and
	leaving channels.
Network Mask	also known as the "Subnet Mask."
OFDM	Developed for wireless applications, Orthogonal Frequency
	Division Multiplexing (OFDM) technology offers superior
	performance-increased data rates and more reliable
	transmissions-than previous technologies, such as DSSS.
	OFDM is a scheme in which numerous signals of different
	frequencies are combined to form a single signal for
	transmission on the medium. OFDM works by breaking one
	high-speed data stream into a number of lower-speed data
	streams, which are then transmitted in parallel. Each lower
	speed stream is used to modulate a subcarrier. Essentially,
	this creates a multi-carrier transmission by dividing a wide
	frequency band or channel into a number of narrower
	frequency bands or sub-channels. OFDM is also used for
	other applications, including powerline networking.
Plug-and-Play	The ability of a computer system to configure expansion
	boards and other devices automatically without requiring the
	user to turn off the system during installation.
Roaming	In an infrastructure mode wireless network, this refers to the
	ability to move out of one access point's range and into
	another and transparently reassociate and reauthenticate to
	the new access point. This reassociation and
	reauthentication should occur without user intervention and
	ideally without interruption to network connectivity. A
	typical scenario would be a location with multiple access
	points, where users can physically relocate from one area to
	another and easily maintain connectivity.
SSID	(Service Set Identifier) - An identification name that wireless
	devices use to make connections. In order for wireless
	devices to communicate, they must all be set to the same
	channel and they all must use the same SSID. For instance, if
	you are using an access point to connect two computers
	using wireless devices, the access point and each of the
	wireless devices must use the same SSID. Even if they are
	set to the same channel, they cannot communicate unless the
	SSID is the same.
Static IP Address	A permanent IP address that is assigned to a node in a TCP/
	IP network.
