Wireless LAN Expert Exam (PW0-300) Objectives

The CWNE certification covering the current objectives will certify that the successful candidate has a firm grasp on
the fundamentals of advanced WLAN troubleshooting, Quality of Service (QoS), and spectrum management, can
describe the features and functions of the IEEE 802.11 standard as amended, and has the skills needed to design,
install, configure, secure, and troubleshoot an advanced 802.11 WLAN enterprise installation. A typical candidate
should have a solid understanding of WLAN administration and security.
The skills and knowledge measured by this examination are derived from a survey of wireless networking experts
and professionals. The subject areas below provide the breakdown of the main objectives of the PW0-300 exam.
