Overview

This module provides an introduction to the rapidly evolving technology of wireless LANs (WLANs). WLANs redefine the way the industry views LANs. Connectivity no longer implies attachment. Wireless networking provides all the features and benefits of traditional LAN technologies without the limitations of wires or cables. The freedom to roam while still maintaining connectivity has helped launch wireless networking to new heights.

After giving reasons for the popularity of wireless networking, this module will list and explain the different types of networking media, identify the basic characteristics of WLANs, and introduce the components of WLANs and their functions.

There are four major factors to consider before implementing a wireless network:

  • High availability
  • Scalability
  • Manageability
  • Open architecture

Finally, this module will explain the use of the wireless spectrum and its conservation as it relates to the future of wireless networking.

NOTE:

It is required that the student study the commands covered in the chapter using the labs and the Command Reference. Not all required commands are covered in sufficient detail in the text alone. Successful completion of this course requires a thorough knowledge of command syntax and application. The Command Reference can be found on the Cisco.com website at the following URL:
