The Wireless Network Administrator Course (that will prepare students for the latest CWNA examination), provides the networking professional a complete foundation of knowledge for entering into or advancing in the wireless networking industry. The instructor will guide the students through the latest CWNA study guide as they cover material that will help ensure the student’s success on their CWNA examination and in their workplace. Your instructor will share their years of field experience as they walk you through a series of lecture and hands-on training labs that will benefit the novice as well as the experienced network professional. Students will benefit from discussions on the latest information on wireless trends, protocols, and standards.

The CWNA certification is the foundation level enterprise Wi-Fi certification for the CWNP Program, and CWNA is required for your CWSP, CWAP, CWDP and CWNE certifications. Your CWNA certification will get you started in your wireless career by ensuring you have the skills to successfully survey, install, and administer enterprise Wi-Fi networks.  The CWNA certification is the foundation for any professional who uses wireless networks. 

If you're preparing for the CWNA exam, you'll find full coverage of radio frequency (RF) technologies, as well as IEEE 802.11 regulations and standards, protocols and devices, network security, and much more. This detailed CWNA Study Guide not only covers all exam objectives, it also includes practical chapter review questions and hands-on exercises. The book's website offers additional practice exams and flashcards, demo software, and more.

BICSI CECs: Course completion certificate can be submitted to BICSI for up to 19 CECs
