Definitions
Access Point
C
ommunication hub for users to connect to a wired LAN. APs are important for
providing heightened wireless security.
ADB
Agile Dual-Band - GeminiG3 radiomodem model that allows 700/800MHz
automatic band switching capability during roaming.
AES
Advanced Encryption Standard (AES) - uses 128-bit encryption to secure data.
Airlink
Physical radio frequency connections used for communications between units.
ARP
Address Resolution Protocol – Maps Internet address to physical address.
AAVL
Autonomous Automatic Vehicle Location. Optional feature that involves using
GPS (Global Positioning System) signals from the mobile unit by the Host PC.
Backbone
The part of a network that connects most of the systems and networks together,
and handles the most data.
Bandwidth
The transmission capacity of a given device or network.
Base
Designates products used as base stations in VIS systems. They currently include
the Paragon family of products up to the Paragon4 radiomodems.
Browser
An application program that provides a way to look at and interact with all the in-
formation on the World Wide Web.
BSC
Base Station Controller - An async controller-modem designed for the radio base
station in mobile systems. A component of Paragon4 radiomodem base stations.
COM Port
RS-232 serial communications ports of the Paragon4 wireless radiomodem.
Cycle Mark
Signal transmitted on an E-DBA network that keeps the network synchronized.
Default Gateway
A device that forwards Internet traffic from your local area network.
DHCP
Dynamic Host Configuration Protocol - A networking protocol that allows ad-
ministrators to assign temporary IP addresses to network computers by "leasing"
an IP address to a user for a limited amount of time, instead of assigning perma-
nent IP addresses.
DNS
Domain Name Server - The on-line distributed database system used to map hu-
man-readable machine names into IP addresses.
Domain
A specific name for a network of computers.
Dynamic IP Addr
A temporary IP address assigned by a DHCP server.
E-DBA
Enhanced Dynamic Bandwidth Allocation – Dataradio proprietary protocol that
schedules all inbound and outbound Airlink traffic to minimize contention.
Ethernet
Ethernet is a frame-based computer networking technology for local area net-
works (LANs). It defines wiring and signaling for the physical layer, and frame
formats and protocols for the media access control (MAC)/data link layer of the
OSI model. Ethernet is mostly standardized as IEEEs 802.3.
Feature Key
Method used to implement customer’s option(s) selected at the time of radiomo-
dem purchase
(factory-installation
) or as add-on
(field-installation)
.
Firewall
A set of related programs located at a network gateway server that protects the
resources of a network from users from other networks.
Firmware
The programming code that runs a networking device.
Fragmentation
Breaking a packet into smaller units when transmitting over a network medium
that cannot support the original size of the packet.
FTP
File Transfer Protocol - A protocol used to transfer files over a TCP/IP network.
