vii
Gateway A device that interconnects two or more networks with different, incompatible communications
protocols and translates among them.
GeminiG3 Third generation of Gemini
PD
VIS products. High specs dual DSP mobile radiomodem with Data-
radio Parallel Decode™ technology
HDX Half Duplex. Data transmission that can occur in two directions over a single line, using separate
Tx and Rx frequencies, but only one direction at a time.
HTTP HyperText Transport Protocol - The communications protocol used to connect to servers on the
World Wide Web.
IPCONFIG A Windows 2000 and XP utility that displays the IP address for a particular networking device.
MAC ADDRESS Media Access Control - The unique address that a manufacturer assigns to each networking de-
vice.
MIB Management Information Base (MIB)-a logical, hierarchically organized database of network
management information. Used in SNMP.
NAT Network Address Translation - NAT technology translates IP addresses of a local area network to
a different IP address for the Internet.
Network A series of computers or devices connected for the purpose of data sharing, storage, and/or
transmission between users.
Network speed This is the bit rate on the RF link between units.
Node A network junction or connection point, typically a computer or work station.
OID An object identifier or OID is an identifier used to name an object and is the numerical equivalent
of a path. In SNMP, an OID consists of numbers separated by decimal points. Structurally, an
OID consists of a node in a hierarchically assigned namespace.
OIP Optimized IP – Compresses TCP and UDP headers, and filters unnecessary acknowledgments.
This makes the most use of the available bandwidth.
OTA Over-The-Air - Standard for the transmission and reception of application-related information in
a wireless communications system
Palette Synchronization patterns used to identify the speed and coding of packets transmitted over-the-air
in E-DBA.
Paragon4 IP-based data radio base station used in mobile networks and designed specifically to fit the needs
of vehicular applications. Runs up to 128 kb/s
Parallel Decode Technology featuring dual receivers for added data decode sensitivity in multi-path and fading
environments. (United States Patent No: 6,853,694 B1)
PHY A PHY chip (called PHYceiver) provides interface to the Ethernet transmission medium. Its pur-
pose is digital access of the modulated link (usually used together with an MII-chip).
The PHY defines data rates and transmission method parameters.
PDU Protocol Data Unit - A PDU is a message of a given protocol comprising payload and protocol-
specific control information, typically contained in a header. PDUs pass over the protocol inter-
faces that exist between the layers of protocols.
Ping Packet INternet Groper - An Internet utility used to determine whether a particular IP address is
online.
PLC Programmable Logic Controller. An user-provided intelligent device that can make decisions,
gather and report information, and control other devices.
Roaming Movement of a wireless node (GeminiG3 radiomodems) amongst Multiple Access Points (Para-
gon4). Paragon4 radiomodems support seamless roaming.
Router A networking device that connects multiple networks together.
