F
FCS	frame check sequence
F-type	A type of connector used to connect coaxial cable to equipment such as the SBG900.
connector
firewall	A security software system on the SBG900 that enforces an access control policy between the
	Internet and the SBG900 LAN.
flow	A data path moving in one direction.
FEC	Forward error correction is a technique to correct transmission errors without requiring the transmitter
	to resend any data.
FDMA	Frequency Division Multiple Access is a method to allow multiple users to share a specific radio
	spectrum. Each active user is assigned an individual RF channel (or carrier) with the carrier frequency
	of each channel offset from its adjacent channels by an amount equal to the channel spacing, which
	allows the required bandwidth per channel.
frame	A unit of data transmitted between network nodes that contains addressing and protocol control data.
	Some control frames contain no data.
frequency	Number of times an electromagnetic signal repeats an identical cycle in a unit of time, usually one
	second, measured in Hz, kHz, MHz, or GHz.
FTP	File Transfer Protocol is a standard Internet protocol for exchanging files between computers. FTP is
	commonly used to download programs and other files to a computer from Web pages on Internet
	servers.
full-duplex	The ability to simultaneously transmit and receive data. See also half-duplex.

G

gain	The extent to which a signal is boosted. A high gain antenna increases the wireless signal level to
	increase the distance the signal can travel and remain usable.
gateway	A device that enables communication between networks using different protocols. See also router.
	The SBG900 enables up to 253 computers supporting IEEE 802.11b, Ethernet, or USB to share a
	single broadband Internet connection.
gateway IP	The address of the default gateway router on the Internet. Also known as the “giaddr.”
address
GHz	Gigahertz — one billion cycles per second.
GUI	graphical user interface
