Certified Wireless Network Administrator (CWNA)


Certified Wireless Network Administrator (CWNA)

The CWNA certification is the foundation-level enterprise Wi-Fi certification for the CWNP Program. Achieving it sets your wireless career on a firm foundation, ensuring you have the skills to successfully survey, install, and administer enterprise Wi-Fi networks.

In this hands-on course, you will 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. Plus, you will explore advanced topics such as VoWLAN deployments, seamless mobile connectivity, and detailed wireless frame analysis. You will use enterprise-class hardware and software tools during live lab exercises, simulating a state-of-the-art production environment.
