Overview:

The Wireless LAN Administration course, whether in an academic format or a 5-day fast-track format, provides the networking professional a complete foundation of knowledge for entering into or advancing in the wireless networking industry. From basic RF theory to link budget math, including topics from troubleshooting to performing a site survey, this course delivers hands on training that will benefit the novice as well as the experienced network professional.


Audience:

This course targets both novice and experienced networking professionals who wish to gain a solid understanding of wireless networking to complement their knowledge of traditional wired networking.


Course Duration:

The Wireless LAN Administration course consists of 40 hours of material, incorporating both lecture and hands-on labs. The class may be taught in a 5-day period.


Certification:

This course may be used - and is the ideal track - for preparing students for the CWNA exam (exam PW0-100).


Prerequisites:

It is recommended that all students have at least a basic knowledge of networking (as exhibited in Net+, CCNA®, CNA, or) prior to enrolling in the course.

Hands-on Lab Exercises

Lab-1: Infrastructure Mode Connectivity

This exercise demonstrates wireless client devices connecting to an access point. Students configure the access point, wireless stations, and view the association table in the access point in order to understand the process a client goes through to become connected to the network. RF output power is explained and client utilities are viewed to show RF signal quality and strength. Access point features, authentication, association, and encryption are all discussed and demonstrated. 802.11a/b/g technologies are each shown independently to demonstrate channel usage and spread spectrum technologies.


Lab 2: Infrastructure Mode Throughput Analysis

This exercise demonstrates the expected throughput achievable 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 and 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. Use of SSIDs, WEP/WPA, channels, and other connectivity factors will be
discussed and demonstrated.


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 increase or decrease the data rate of the wireless connection in order to maintain optimum connectivity with the access point. Environmental factors will be analyzed. A basic site survey will be performed during this lab exercise using 802.11a/b/g technologies.


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,p ...''
