IPCONFIG A Windows 2000 and XP utility that displays the IP address for a particular net-
working device.
MAC ADDRESS Media Access Control - The unique address that a manufacturer assigns to each
networking device.
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, stor-
age, 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.
OIP Optimized IP – Compresses TCP and UDP headers, and filters unnecessary ac-
knowledgments. 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
Paragon3
IP-based data radio base station used in mobile networks and designed specifi-
cally 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.
Ping Packet INternet Groper - An Internet utility used to determine whether a particu-
lar 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) amongst Multiple Access Points
(Paragon3). GeminiG3 supports seamless roaming.
Router A networking device that connects multiple networks together.
RS-232 Industry–standard interface for data transfer.
Smart Combining Digital processing method used to combine “Spatial Diversity” signals to opti-
mize performance. (See Parallel Decode)
SRRCnFSK Square Root Raised Cosine (n = level) Frequency Shift Keying. Type of fre-
quency modulation of data signals performed by the Paragon3 radiomodem.
Spatial Diversity Composite information from independent diversity branches using antennas
spaced apart is used with “Smart Combining” to minimize fading and other unde-
sirable effects of multipath propagation. (See Parallel Decode)
Static IP Address A fixed address assigned to a computer or device that is connected to a network.
Static Routing Forwarding data in a network via a fixed path.
Subnet Mask An address code that determines the size of the network.
Switch (Ethernet) A data switch that connects computing devices to host computers, allowing a
large number of devices to share a limited number of ports.
Sync Data transmitted on a wireless network that keeps the network synchronized.
TCP/IP Transmission Control Protocol/Internet Protocol - A set of instructions PCs use
to communicate over a network.
Telnet A user command and TCP/IP protocol used for accessing remote PCs.
TFTP Trivial File Transfer Protocol - A version of the TCP/IP FTP protocol that has no
directory or password capability.
Topology The physical layout of a network.
Transparent A transparent unit transmits all data without regard to special characters, etc.
UDP User Datagram Protocol - A network protocol for transmitting data that does not
require acknowledgement from the recipient of the data that is sent.
