The CWNA Certification Guide teaches you how to install, manage, and support wireless networks, while also preparing for the Certified Wireless Network Administrator (CWNA) certification exam.
This study of wireless networking combines radio frequency (RF) and local area networking (LAN) technology fundamentals. This text begins with the basic concepts and building blocks of the convergence between RF and networking technologies. It focuses on the technologies and tasks vital to installing, managing, and supporting wireless networks, based on the exam objectives of the CWNA certification exam #PW0-100. You will learn wireless technology standards, governing bodies, hardware, RF math, RF behavior, security, troubleshooting, and site survey methodology.
The CWNA certification is a Planet3 Wireless certification program, similar to Avaya, Cisco, Novell, and Microsoft, yet vendor neutral like CompTIA and NACSE. The certification gives networking professionals a standardized set of measurable wireless LAN skills and employers a standard level of wireless LAN expertise to require of their employees.
The wireless LAN industry is still in its infancy, much like the world of networking LANs and WANs was in the early 1990s. Learning wireless networking sets you apart from your peers and your competition.
