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.
