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.

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.

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.

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.
