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 across busy streets make the
installation of LANs either impossible or very expensive.
b) Temporary workgroups
Consider situations in parks, athletic arenas, exhibition centers, disaster-
recovery, 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 sites 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.
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

EUB9801 –300Mbps 802.11 a/b/g/n Dual Band Wireless N USB Adapter

This is the simplest network configuration with several computers
equipped with the PC Cards that form a wireless network whenever they
are within range of one another. In ad-hoc mode, each client is peer-to-
peer, would only have access to the resources of the other client and
does not require an access point. This is the easiest and least expensive
way for the SOHO to set up a wireless network. The image below depicts
a network in ad-hoc mode.
b) Infrastructure Mode
The infrastructure mode requires the use of an Access Point (AP). In this
mode, all wireless communication between two computers 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.

2 USB Adapter for Windows (XP & Vista)
Before You Begin
During the installation, XP may need to copy systems files from its installation CD.
Therefore, you may need a copy of the Windows installation CD at hand before
installing the drivers. On many systems, instead of a CD, the necessary installation
files are archived on the hard disk in C:\WINDOWS \OPTIONS\CABS directory.
WiFi Alliance certification recommends WPA2 AES to be the security
mechanism under 11N mode. System driver will automatically bring down
wireless data rate to 54Mbps if other security method such as WEP or WPA
is used under 11n mode.
If your 11N router is using security mechanism other than WPA2 AES, you
are recommended to disable security setting or change it to WPA2 AES to
fully utilize 11N capability. This policy has no effect if connecting with b/g
only wireless access point.

Authentication and Security
The Security tab allows you to configure the authentication and encryption
settings such as: WEP, WPA, WPA-PSK, WPA2, and 802.1x. Each security
option is described in detail below.
WEP Encryption
The WEP tab displays the WEP settings. Encryption is designed to make the
data transmission more secure. You may select 64 or 128-bit WEP (Wired
Equivalent Privacy) key to encrypt data (Default setting is Disable). WEP
encrypts each frame transmitted from the radio using one of the Keys from a
panel. When you use WEP to communicate with the other wireless clients, all the
wireless devices in this network must have the same encryption key or pass
phrase. The following information is included in this tab, as the image depicts
below.
WiFi Alliance certification recommends WPA2 AES to be the security
mechanism under 11N mode. System driver will automatically bring down
wireless data rate to 54Mbps if other security method such as WEP or WPA is
used under 11n mode.
If your 11N router is using security mechanism other than WPA2 AES, you
are recommended to disable security setting or change it to WPA2 AES to fully
utilize 11N capability. This policy has no effect if connecting with b/g only
wireless access point.

WPA, WPA2 Authentication & TKIP, AES Encryption
WPA (Wi-Fi Protected Access) was designed to improve upon the security
features of WEP (Wired Equivalent Privacy). This is used along with 802.1x
security setting. The technology is designed to work with existing Wi-Fi products
that have been enabled with WEP. WPA provides improved data encryption
through the Temporal Key Integrity Protocol (TKIP), which scrambles the keys
using a hashing algorithm and by adding an integrity-checking feature which
makes sure that keys haven’t been tampered with. 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 authentication software stored in a server
to interact with its counterpart in the client.

†Click on the OK button to save the changes.
†Show Password check box. If you want to make sure the accuracy of
password you type, click the Show Password box to check it.
WPA-PSK & WPA2-PSK Authentication & TKIP, AES Encryption
WPA–PSK (Pre-shared Key) is used in a Pre Shared Key mode that does not
require an authentication server. Access to the Internet and the rest of the
wireless network services is allowed only if the pre-shared key of the computer
matches that of the Access Point. This approach offers the simplicity of the WEP
key, but uses stronger TKIP encryption. 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 authentication software stored in a server to interact with its
counterpart in the client.
†Authentication Type: Select WPA-PSK or WPA2-PSK from the drop-down
list.
†Encryption: Select TKIP or AES from the drop-down list.

†Show Password check box. If you want to make sure the accuracy of
password you type, click the Show Password box to check it.
LEAP Authentication
LEAP (Lightweight Extensible Authentication Protocol) also known as Cisco-
Wireless EAP provides username/password-based authentication between a
wireless client and a RADIUS server. LEAP is one of several protocols used with
the IEEE 802.1X standard for LAN port access control. LEAP also delivers a
session key to the authenticated station, so that future frames can be encrypted
with a key that is different than keys used by others sessions. Dynamic key
delivery eliminates one big vulnerability; static encryption keys that are shared by
all stations in the WLAN. 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 authentication software stored in a server to interact with its counterpart in the
client

19
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 authentication
software stored in a server to interact with its counterpart in the client.
PEAP Authentication with EAP/TLS Smartcard
EAP/TLS Smartcard provides for certificate-based and mutual authentication of
the client and the network. It relies on client-side and server-side certificates to
perform authentication and can be used to dynamically generate user-based and
session-based WEP keys to secure subsequent communications between the
WLAN client and the access point.
†Authentication Type: Select PEAP from the drop-down list.
†Protocol: If your network uses TLS or Smart Card to authenticate its users,
select TLS/Smartcard from the drop down list. TLS (Transport Layer
Security) is an IETF standardized authentication protocol that uses PKI
(Public Key Infrastructure) certificate-based authentication of both the client
and authentication server.
†Identity: Enter the user name.
†Click on the OK button to save the changes.
802.1x with TTLS with EAP-MD5, MS-CHAP, MS-CHAPv2
802.1X provides an authentication framework for wireless LANs allowing a user
to be authenticated by a central authority. 802.1X uses an existing protocol 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 authentication
software stored in a server to interact with its counterpart in the client. TLS

802.1x CA Server
Depending on the EAP in use, only the server or both the server and client may
be authenticated and require a certificate. Server certificates identify a server,
usually an authentication or RADIUS server to clients. Most EAPs require a
certificate issued by a root authority or a trusted commercial Certificate Authority.
