CHAPTER 5
Wireless LAN Design
Wireless LANs (WLAN) allow users to connect to network resources and services with-
out using cables. With WLANs, users connect to the network in common areas, away
from their desk, and in areas that do not easily accommodate the installation of wired ca-
bling, such as outdoors and in designated historical sites. This chapter describes WLAN
technologies, design, and Cisco solutions.
The “Do I Know This Already?” quiz helps you identify your strengths and deficiencies in
this chapter's topics.
The eight-question quiz, derived from the major sections in the “Foundation Topics” por-
tion of the chapter, helps you determine how to spend your limited study time.
Ta ble 5 -1 outlines the major topics discussed in this chapter and the “Do I Know This Al-
ready?” quiz questions that correspond to those topics.
