TERM DEFINITION
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.
FMDA
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 contain
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.

TERM DEFINITION
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 SVG2500 enables up to
245 computers supporting IEEE 802.11b, Ethernet, or USB to
share a single broadband Internet connection.
gateway IP
address
The address of the default gateway router on the Internet. Also
known as the “giaddr.”
GHz
Gigahertz — one billion cycles per second
GUI
