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 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.
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.

EUB9701/9702 and EPI-9701series --IEEE802.11b/g/n Wireless LAN ClientAdapter Version 1.0

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 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.

2.4.2 WPA, WPA2 Authentication & TKIP, AES Encryption
WPA (Wi-Fi Protected Access) was designed to improve upon the security
features of WEP (Wired Equivalent Privacy). 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 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.

Show Password check box. If you want to make sure the accuracy of
password you type, click the Show Password box to check it.
2.4.3 WPA-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 or WPA2 from the drop-down list.
Encryption: Select TKIP or AES from the drop-down list.
WPA Preshared key: Enter a pass phrase which is between 8 and 32
characters long.
