CWNA Certified Wireless Network Administrator Test Essentials
CWNA is the top vendor neutral certification for wireless networking. What is the knowledge being measured? Here are the CWNA Test Essentials:
Introduction to Wireless LANs
It is also important to understand the driving forces behind wireless LAN which requires knowledge of typical applications. And what makes up the wireless LAN industry?
What are the many different items that connect antennas to other wireless LAN hardware?. Antennas are most often used to increase the range of wireless LAN systems, but proper antenna selection can also enhance the security of a wireless LAN. CWNAs must know the attributes of different antenna categories and the appropriate method of installation for each kind of antenna.
IEEE 802.11 Regulations and Standards
It is necessary to be able to define and describe spread spectrum technologies and some of their uses. The different types of spread spectrum technologies need to be differentiated, compared, and discussed in depth. It is also important to know how spread spectrum technology is implemented in wireless LANs as well as what the IEEE 802.11-2007 Standard represents. .
Which IEEE 802.11 Industry Organizations exist and what are their roles? It is essential to have knowledge about the organizations that create standards that guide the evolution and development of wireless LANs. Candidates should know the major organizations that contribute to growth and education in the wireless LAN marketplace: These include the Regulatory Domain Governing Bodies and the IEEE.
Good understanding the regulations and the standards in the wireless LAN sphere enables candidates to ensure they implement wireless systems that meet expected standards.
IEEE 802.11 Protocols and Devices
This looks at authentication and association and the critical processes involved. Important considerations are the WLAN service sets concepts and the power management features of WLANs. Concepts on WLAN frames need to be well understood and applied. What are the differences diffrent frame types and how do wireless LANs avoid collisions.Connectivity methods of an IEEE 802.11 WLAN must also be treated. Different categories of wireless network infrastructure equipment and some of variations within each category need to be covered. The hardware items within each category are particularly important. Candidates should understand the purpose of WLAN infrastructure devices and WLAN client devices and know how to install, configure, secure, and manage them.
IEEE 802.11 Network Implementation
It’s important to be able to identify the various appropriate
technology environments for WLAN and know how to implement in the
settings. Environments could include corporate enterprise, connecting to
remote areas, bridging buildings, Small Office / Home Office (SOHO),
healthcare, educational, law enforcement, mobile office networking, etc.
You must also know the common challenges to be faced in WLAN implementation and
how to overcome such roadblocks. What does successful implementation of
Also covered is Power over Ethernet (PoE), an important technology in today’s wireless networks that has spawned new product lines and new standards. WLAN architectures are also core - it is critical to know to how to implement autonomous APs and WLAN controllers that use centralized and/or distributed forwarding. Also covered is the management of autonomous APs, WLAN controllers, and mesh nodes. Most of these topics are defined directly in the 802.11 standard, and are required for implementation 802.11 – compliant hardware. It is critical to know how clients connect to an access point, the terms used for organizing wireless LANs, and how power management is accomplished in wireless LAN client devices.

ABOUT THE EXAM
A typical candidate should have Network+, CCNA, CAN or MCP certification or equivalent knowledge, although
these certifications are not required before taking the actual exam.
The skills and knowledge measured by this examination are derived from a survey of wireless networking experts and professionals. The results of this survey were used in weighing the subject areas and ensuring that the weighting is representative of the relative importance of the content.
