1.5 Applications

The wireless LAN products are easy to install and highly efficient. The following list
describes some of the many applications made possible through the power and
flexibility of wireless LANs:

a) Difficult-to-wire environments

There are many situations where wires cannot be laid easily. Historic
buildings, older buildings, open areas and acro ss busy streets make the
installation of LANs either impossible or very expensive.

b) Temporary workgroups

Consider situations in parks, athletic arenas, exhibition centers, disaster­recovery, temporary offices and construction sites where one wants a
temporary WLAN established and removed.

c) The ability to access real-time information

Doctors/nurses, point-of-sale employees, and warehouse workers can
access real-time information while dealing with patients, serving
customers and processing information.

d) Frequently changed environments

Show rooms, meeting rooms, retail stores, and manufacturing si tes where
frequently rearrange the workplace.

e) Small Office and Home Office (SOHO) networks

SOHO users need a cost-effective, easy and quick installation of a small
network.

f) Wireless extensions to Ethernet networks

Network managers in dynamic environments can minimize the overhead
caused by moves, extensions to networks, and other changes with
wireless LANs.

g) Wired LAN backup

Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks.

h) Training/Educational facilities

Training sites at corporations and students at universities use wireless
connectivity to ease access to information, information exchanges, and
learning.

1.6 Network Configuration

To better understand how the wireless LAN products work together to create a
wireless network, it might be helpful to depict a few of the possible wireless LAN PC
card network configurations. The wireless LAN products can be configured as:

a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.
b) Infrastructure for enterprise LANs.

a) Ad-hoc (peer-to-peer) Mode

This is the simplest network configuration with several computers
equipped with the PC Cards that form a w ireless network whenever they
are within range of one another. In ad-hoc mode, each client is peer-to­peer, would only have access to the resources of the other client and
does not require an access point. T his is the easiest and least expensive
way for the SOHO to set up a wireless network. The i mage below depicts
a network in ad-hoc mode.

7

IEEE 802.11b/g Wireless USB 2.0 Adapter Version 1.2

b) Infrastructure Mode

The infrastructure mode requires the use of an access point (AP). In this
mode, all wireless communication between two compu ters has to be via
the AP. It doesn’t matter if the AP is stand-alone or wired to an Ethernet
network. If used in stand-alone, the AP can extend the range of
independent wireless LANs by acting as a repeater, which effectively
doubles the distance between wireless stations. The image below
depicts a network in infrastructure mode.

allows the exchange of clear text authentication credentials across the network.
The GTC method does provide a way to move a si mple username and password
from client to server using an EAP method, so it can be used to provide an
authentication method. Naturally, if EAP-GTC is used to transport reusable
passwords, it must be used inside a tunnel for protection and server
authentication. EAP-GTC can be used with both TTLS and PEAP.

Select the WPA radio button, and then select PEAP (EAP-GTC) from the drop-

called EAP. EAP (Extensible Authentication Protocol) is an extension to the PPP
protocol that enables a variety of authentication protocols to be used. It passes
through the exchange of authentication messages, allowing the authe nti cation
software stored in a server to interact with its counterpart in the client.

Select the 802.1x radio button, and then select EAP – TLS or EAP – TTLS from
