Enterprise Wi-Fi Administration (CWNA)

 

The CWNA certification is the foundation-level enterprise Wi-Fi certification for the CWNP Program. Achieving it provides your wireless career with a firm foundation and ensures 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. Explore advanced topics such as VoWLAN deployments, seamless mobile connectivity, and detailed wireless frame analysis, and use enterprise-class hardware and software tools during live lab exercises, simulating a state-of-the-art production environment. As an added bonus, you will receive a free exam voucher.
