1.5 Applications
. 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 easily installed. 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, 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) Dynamic environments
Show rooms, meeting rooms, retail stores, and manufacturing sites where
the workplace is frequently rearranged.
e) Small Office and Home Office (SOHO) networks
SOHO users need a cost-effective, easy–to-install 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.

1.6 Network Configuration
To better understand how wireless devices work together to create a wireless
network, it might be helpful to depict a few of the possible wireless network
configurations. Wireless devices can be configured as:
a) Ad hoc (or peer-to-peer)
b) Infrastructure
a) Ad hoc (peer-to-peer) Mode
In ad hoc mode, each client is peer-to-peer. The client would only have
access to the resources of the other client. Ad hoc mode 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 above depicts a
network in Ad hoc mode.
108Mbps 802.11g High Power Wireless USB 2.0 Adapter
b) Infrastructure Mode
Infrastructure mode requires the use of an access point (AP). In this
mode, all wireless communication between clients passes through an 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. The image below depicts a
network in infrastructure mode.

3.2.3.2
WPA / WPA2– TLS, TTLS
WPA2 (Wi-Fi Protected Access 2) provides network administrators with a high
level of assurance that only authorized users can access the network. WPA (WiFi Protected Access) was designed to improve upon the security features of WEP
(Wired Equivalent Privacy). The technology is designed to work with existing WiFi 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.
Select the WPA/WPA2 radio button, and then select EAP – TLS or EAP – TTLS
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.

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.
Select the WPA/WPA2 radio button, and select LEAP from the drop-down list.

3.2.3.11 802.1x – LEAP
LEAP (Lightweight Extensible Authentication Protocol) also known as CiscoWireless 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.
Select the 802.1x radio button, and then select LEAP from the drop-down list.

3.2.3.12 802.1x – EAP-FAST
EAP-FAST allows customers who cannot enforce a strong password policy to
deploy an 802.1X EAP type that does not require digital certificates. This method
supports a variety of user and password database types and password expiration
and change. It is flexible, easy to deploy, and easy to manage. For example, a
customer using Cisco LEAP who cannot enforce a strong password policy and
does not want to use certificates can migrate to EAP-FAST for protection from
dictionary attacks. (See help menu on configuration utility for
more details)
