Certified Wireless Network Administration
Wireless networking is today's fastest growing LAN solution--providing
flexibility, cost savings, and extended communications, as wireless
LANs explode in popularity learning all the good, bad and ugly
of wireless technology can be daunting.
The Wireless LAN Administration training course offers detailed
instruction on the foundation concepts and technologies of wireless
data networking. This hands-on, defense in-depth class has 10+
labs to give you the chance to use wireless products from vendors
like AirMagnet, CISCO, PROXIM, YDI and more.
Our expert instructors take you through everything you need
to know to do a proper wireless site survey, design and implement
a WLAN. By earning the Certified Wireless Network Administrator
(CWNA) credential, the first step toward the CWNE certification,
network engineers and administrators demonstrate that they have
the skills necessary to administer, install, configure, and
troubleshoot wireless network systems.

Lab 1 - Infrastructure Mode Connectivity
This exercise demonstrates wireless client devices connecting
to an access point using matching SSIDs and WEP settings. Students
view the association table in the access point in order to understand
the process a client goes through in order to become connected
to the network. RF output power is explained and client utilities
are viewed to show RF signal quality and strength.
Lab 2: Infrastructure Mode Throughput Analysis
This exercise demonstrates the expected throughput achieved
from a wireless station to a wired station and a wireless station
to a wireless station using FTP and throughput measuring software.
The point of this lab is for the student to understand the half-duplex
nature of wireless LANs and how the data rate relates to actual
throughput in a real-world scenario. Access point frame relay
is proven and explained.
Lab 3: Ad Hoc Connectivity & Throughput Analysis
In this exercise, wireless clients will connect to each other
without use of an access point. Beaconing and channel configuration
in an Ad Hoc environment will be explained and throughput will
be analyzed and compared against an infrastructure environment.
Lab 4: Cell Sizing and Automatic Rate Selection (ARS)
in an Infrastructure Environment
In this exercise, RF cell sizing and ARS will be demonstrated.
Cell sizing is important for seamless connectivity while roaming
and for security purposes. ARS is the wireless LAN client's
ability to speed up or slow down the wireless connection in
order to maintain optimum connectivity with the access point.
Environmental factors will be analyzed.
Lab 5: Co-Channel and Adjacent Channel Interference
In this exercise, the effects of co-channel and adjacent channel
interference are demonstrated and explained. Throughput tests
using FTP and throughput measurement software are performed
using fully-overlapping, partially-overlapping, and non-overlapping
channels. Effects are analyzed and compared.
Lab 6: Rudimentary Security Features
In this exercise, the security features specified in the IEEE
802.11 standard are demonstrated in a mobile environment. Wireless
clients attempt roaming between access points while using like
and different Service Set Identifiers (SSIDs), MAC filters,
and Wired Equivalent Privacy (WEP). Configuration, use, and
security issues are discussed and explained.
Lab 7: Dynamic WEP Keys and Mutual Authentication using 802.1x/EAP
and RADIUS
In this lab the need for wireless security stronger than available
in static WEP is explained, and port-based access control with
EAP authentication is demonstrated and explained in this exercise.
Cisco's proprietary Lightweight EAP is used with RADIUS for
scalability of authentication. The 802.1x/LEAP association process
is analyzed, and rotating unicast and broadcast keys are explained.
Lab 8: Wireless VPNs using PPTP tunnels and RADIUS
In this exercise, the access point is the VPN tunnel server
and the PPTP VPN client software built into Microsoft Windows
is used to establish an encrypted VPN tunnel from the wireless
client to the access point. The access point then sends the
authentication request to a RADIUS server and a tunnel is established.
Use of the PPTP protocol with encryption in a wireless environment
is discussed and explained.
