Wireless LAN Foundations Training Class

Course ID: 20195

Wireless LAN Foundations Training Seminar

Learn how to design, secure, and support wireless networks through detailed
course discussion and a broad range of hands-on configuration and testing
exercises. Learn in-depth security principles and troubleshooting techniques.
Gain a full understanding of how radio frequency affects networking so you can
perform site surveys, design a high-performance network, and protect both users
and sensitive data from potential intruders.
After covering fundamental concepts of deploying a secure WLAN, you will
explore advanced topics such as VoWLAN deployments, seamless mobile
connectivity, and detailed wireless frame analysis. Enterprise class hardware
and software tools are used during live lab exercises in order to simulate a
state-of-the-art production environment.
This course is excellent as part of an overall study strategy for the CWNP
certification CWNA. Full CWNA discussion concepts are covered with lab emphasis
on real-world solutions, as well as many CWSP and CWNE concepts. This class is
also part of our Wireless Specialist Certificate track.
Preparing for the CWNA certification? This course includes a CWNA study
guide, certification practice exam, and test voucher. It also includes 1-year
access to our 50-book Online Networking Reference Library with titles specially
selected to reinforce course concepts.
