Introduction
The Certified Wireless Network Administrator (CWNA) understands standards and operations of 802.11 wireless networks. Responsibilities include deploying, managing, monitoring, and basic troubleshooting of these networks. The CWNA has the ability to describe devices and operations of current WLAN technologies.

The CWNA exam has no prerequisites; however, the following are recommended before attempting the CWNA exam:
● Basic knowledge of networking (routers, switches, cabling, etc.)
● Basic knowledge of TCP/IP
● At least 1 year of work experience with wireless LAN technologies

The skills and knowledge measured by this examination are derived from a Job Task Analysis (JTA) involving wireless networking experts (CWNEs) and professionals.
