ETS European Telecommunications Standard
ETSI European Telecommunications Standards Institute. A non-profit organization
producing voluntary telecommunications standards used throughout Europe, some
of which have been adopted by the EC as the technical base for Directives or
Regulations.
GPS Global Positioning System. A system that uses satellites, receivers and software to
allow users to determine their precise geographic position.
GRE General Routing Encapsulation. A method or technique of adding an IP standard
header and trailer to a message that does not follow IP protocols. The encapsulated
message is sent over a public network while received messages are stripped of the
wrapper and processed. This permits non-standard data and totally encrypted
messages to use the Internet. The technology is an important element in Virtual
Private Network (VPN) offerings.
HP High Power.
IEEE Institute of Electrical and Electronics Engineers. IEEE (pronounced I-triple-E) is an
organization of engineers, scientists, and students. The IEEE is best known for
developing standards for the computer and electronics industry. In particular, the
IEEE 802 standards for local-area networks are widely followed.
IEEE 802.16 Also known as WIMAX. A group of broadband wireless communications standards
for metropolitan area networks (MANs) developed by a working group of the IEEE.
IEEE 802.16e 802.16e, also known as 802.16-2005, is an IEEE standard addressing mobility of
wireless broadband (WiMax). IEEE 802.16e is sometimes called Mobile WiMAX,
after the WiMAX forum for interoperability. 802.16e, based on an existing WiMAX
standard 802.16a, adds WiMAX mobility in the 2-to-6 GHz-licensed bands. 802.16e
allows for fixed wireless and mobile Non Line of Sight (NLOS) applications primarily
by enhancing the OFDMA (Orthogonal Frequency Division Multiple Access).
IEEE 802.1p A QoS method - A three-bit value that can be placed inside an 802.1Q frame tag.
IEEE 802.1q The IEEE 802.1q standard defines the operation of VLAN Bridges that permit the
definition, operation and administration of Virtual LAN topologies within a Bridged
LAN infrastructure. The 802.1q specification establishes a standard method for
inserting VLAN membership information into Ethernet frames. A tag field containing
VLAN (and/or 802.1p priority) information can be inserted into an Ethernet frame,
carrying VLAN membership information.
IEEE 802.3 A Local Area Network protocol suite commonly known as Ethernet. Ethernet uses
Carrier Sense Multiple Access bus with Collision Detection CSMA/CD. This method
allows users to share the network cable. However, only one station can use the
cable at a time. A variety of physical medium dependent protocols are supported.
IF Intermediate Frequency. Radio communications systems modulate a carrier
frequency with a baseband signal in order to achieve radio transmission. In many
cases, the carrier is not modulated directly. Instead, a lower IF signal is modulated
and processed. At a later circuit stage, the IF signal is converted up to the
transmission frequency band.
