Wireless LANs -- 'CCNA Official Exam Certification Library, Third Edition,' Chapter 11

This chapter examines the basics of WLANs. In particular, the first section introduces the concepts, protocols, and standards used by many of the most common WLAN installations today. The chapter then examines some basic installation steps. The last major section looks at WLAN security, which is particularly important because the WLAN signals are much more susceptible to being intercepted by an attacker than Ethernet LANs. The chapter also includes a helpful "do I know this already" quiz, to determine whether you need to read the full chapter or can move ahead to the exam preparation section.
