CWNA: Certified Wireless Network Administrator

The Certified Wireless Network Administrator (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 the five-day Enterprise Wi-Fi Administration (CWNA) course is to add Wi-Fi expertise to a networking professional’s skill-set, while covering all CWNA-109 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.
