2 Introduction
Why Choose Wireless?
Wireless Local Area Networks (WLANs) are cellular computer networks that transmit and
receive data with radio signals instead of wires. Wireless LANs are used increasingly in both
home and office environments, and public access locations such as airports, coffee shops and
universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more efficiently and with increased mobility and flexibity. The absence of
cabling and other fixed infrastructure have proven to be beneficial for users and cost-effective
for service providers.
Wireless users can use the same applications they use on a wired network. Wireless adapter
cards used on laptop and desktop systems support the same protocols as Ethernet adapter cards.
It may sometimes be desirable for mobile network devices to link with conventional Ethernet
LANs to connect with servers, printers or the Internet supplied through the wired LAN. A
wireless Access Point (AP) is a device used to provide this link.
Wireless LAN technology is used for many different purposes:
zMobility - Productivity increases when people have access to data in any location
within the operating range of the WLAN. Management decisions based on real-time
information can significantly improve worker efficiency.
zLow Implementation Costs - WLANs are easy to set up, manage, change and
relocate. Networks that frequently change can benefit from the ease of WLAN
implementations. WLANs can operate in locations where the installation of physical
wiring may be impractical.
zInstallation and Network Expansion - Installing a WLAN can be fast and easy and
can eliminate the need to route cabling through walls and ceilings. Wireless
technology allows the network to go where wires cannot go—even outside the home
or office.
zInexpensive Solution - Wireless networking devices are as competitively priced as
conventional Ethernet networking devices.
zScalability - WLANs can be configured in a variety of ways to meet the needs of
specific applications and installations. Configurations are easily changed, and range
from peer-to-peer networks (suitable for a small number of users) to larger
infrastructure networks that can accommodate hundreds or thousands of users,
depending on the number of wireless devices deployed.

AG 2100
Introduction 3
Welcome to the Nomadix AG 2100
The Nomadix AG 2100 is a cost-effective, integrated Wi-Fi™ HotSpot connectivity device
that combines our full suite of public access features with a powerful Wi-Fi Access Point—
maximizing range and coverage to create a superior solution for single- or dual-cell HotSpot
locations.
Product Definitions
The AG 2100 supports the IEEE 802.11b and the faster 802.11g wireless standards within the
2.4 GHz band.
Ensuring Compatibility
The AG 2100 is compatible with most popular operating systems, including Macintosh, Linux
and Windows, and can be easily integrated into a large network.
By strictly adhering to IEEE standards, the AG 2100 allows users to securely access the data
they want, when and where they want it, and enjoy the freedom that wireless networking
delivers.
Nomadix AG 2100

AG 2100
4 Introduction
Offering Speed and Efficiency
The AG 2100 is a dual-mode, dualband Access Point providing the most expanded user
bandwidth available in an Access Point. Wireless clients can now connect to the AG 2100
using any one of its 14 non-overlapping channels to transfer data at speeds never before
achievable in a wireless device.
The AG 2100 operates seamlessly and simultaneously in the 2.4 GHz frequency spectrum
supporting the 802.11b and the faster (up to 54 Mbps) 802.11g wireless standards.
802.11g wireless standards utilize OFDM (Orthogonal Frequency Division Multiplexing)
technology. OFDM works by splitting the radio signal into multiple smaller sub-signals that are
then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the
amount of crosstalk (interference) in signal transmissions, allowing you to transfer large files
quickly, or even watch a movie in MPEG format over your network without any noticeable
delays.
In addition to its compatibility with 802.11g devices, the AG 2100 is compatible with 802.11b
devices. For HotSpots that already use 802.11b devices, the AG 2100 is the ideal way to
expand an existing network, enabling even more users to communicate with each another,
access data and connect to the Internet.
By offering transfer rates up to 54 Mbps, the AG 2100 enables large data packets to travel from
the router to a remote desktop or roaming laptop PC at up to five times the speed of previous
wireless devices.
See also, “Defining Wireless Configuration {Wireless Configuration}” on page 229.
Optimizing Performance
Network administrators can partition system usage by segmenting the users on the wireless
network according to frequency band. This type of user segmentation optimizes the product’s
performance and delivers the best network experience to all users.
Providing Effective Security
The AG 2100 is ideal for network administrators who require additional management, firewall,
and other network security features. All system settings are easily accessible from the product’s
embedded web-based user interface.
The AG 2100 incorporates the 802.1x standard for wireless user authentication, WPA (Wi-Fi
Protected Access), and WEP (Wired Equivalent Privacy).

AG 2100
Introduction 5
Enabling Flexible Deployment Options
The AG 2100 enables a wide variety of network deployment options by supporting IEEE
802.11b/g for maximum flexibility in the types of users supported, and the 10/100 WAN
interface enables connectivity into a variety of backhaul types.

AG 2100
6 Introduction
Key Features and Benefits
The AG 2100 allows carriers to deploy Wi-Fi service into a wide range of large or small public
access locations while keeping deployment costs low.
Key features and benefits include:
Transparent Connectivity
Resolving configuration conflicts is difficult and time consuming for network users who are
constantly on the move, and costly to the solution provider. In fact, most users are reluctant to
make changes to their computer’s network settings and won’t even bother. This fact alone has
prevented the widespread deployment of broadband network services.
Our patented Dynamic Address Translation™ (DAT) functionality offers a true “plug and
play” solution by providing transparent broadband network access and the ability to acquire
new customers onsite—no need for configuration changes to the client computer or any client-
side software.
DAT greatly reduces provisioning and technical support costs and enables carriers to deliver an
easy to use, customer-friendly service.
