Certified Wireless Network Administrator (CWNA)

Get a head start right out of the gate with a Certified Wireless Network Administrator
(CWNA) certification. It is the base certification for Enterprise Wi-Fi within the CWNP
family of certifications and a springboard toward earning your security, design, analysis
and network expert certifications. 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-108 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.
As an added bonus, you will receive a free exam voucher.
