Enterprise Wi-Fi Administration (CWNA)

Learn how to prepare for the CWNA exam while learning to survey, secure, and troubleshoot enterprise-class Wi-Fi networks.

GK# 3603

Course Overview

TOP

The CWNA certification is the foundation-level enterprise Wi-Fi certification for the CWNP Program.  Achieving it enhances your networking career profile, providing evidence that you have sought after Wi-Fi knowledge and skills. 

The goal of this course is to add Wi-Fi expertise to a networking professional’s skillset, while covering all CWNA-107 exam topics.  The course begins with discussion topics and hands-on lab exercises covering the basic operation of 802.11 Wi-Fi technology.  Once a base of Wi-Fi knowledge is established, enterprise relevant topics such as Wi-Fi design, security, and troubleshooting are covered.  You will use enterprise-class hardware and software tools during live lab exercises, all accessible remotely for any instructor-led or virtual class.
