Wireless LANs Defined
This lesson will explore the overall comparisons between wired and wireless LANs along with wireless network types. An explanation and comparison is also made between ad-hoc and infrastructure modes. Finally, the concept of the service set is seen along with a survey of the wireless standards bodies.

RF Mathematics
Well...nobody said there "wasn't going to be any math" so let's learn about watts, milliwatts, decibels, dBm, dBi, dBd, and EIRP.

Antenna Communications
This nugget covers the often forgotten workhorse of the wireless implementation - the antenna. What would we do without it? Not much in our wireless network for sure. This lesson addresses the principles of antennae (or is it antennas?), common antenna types, and antenna connectors and hardware.

Wireless Regulation Bodies, Standards, and Certifications
In this interesting module we will expand on some of the entities we were introduced to in Lesson 2 of this series. We'll explore the various regulatory bodies - after all we can't have wireless anarchy - and then learn about the various IEEE standards including: 802.11, 802.11b, 802.11g, 802.11a, and 802.11n.

Wireless Media Access (and VLANs)
This nugget really gets under the hood at the actual behavior of 802.11 frames. Topics covered in this lesson include: wireless frame types and IFS periods, basic frame transmission, wireless frame headers, a survey of wireless frames, some wireless road trips, and using VLANs for wireless.

00:33:46 |
|
|
|
Controller-Based Network Management
This nugget is a continuation of the previous nugget as we investigate monitoring the network through the controller, monitoring and managing APs, monitoring rogues, client monitoring and management, as well as internal DHCP scope configuration.
|
00:28:02 |
|
|
|
Configuring Standalone Access Points
Now is your chance to learn how to connect to a standalone AP, use the express setup web interface, perform setup of security setup, and converting to LWAPP mode.
|

|
|
|
Wireless Mobility Express
This nugget explores the small business solution from Cisco known as the Cisco Mobility Express. We look at product options for the initiative, the 521 WL Express Lightweight AP, the 526 Mobility Express Controller, setting up the solution through the CLI, and using the web-based GUI management tool.

WLAN Security (Part 1)
Here is one of the most vital aspects of wireless networking - security. This first security module addresses threats to wireless networks, an overview of WLAN security, establishing 802.11 security, centralized authentication, and Local EAP.
|
00:45:16 |
|
|
|
WLAN Security (Part 2)
This is a continuation of part one where the following protocols are covered: EAP-TLS, EAP-FAST, PEAP, and WPA/WPA2. Finally, the topic of configuration on WLC and the client is covered.
|
00:38:17 |
|
|
|
Cisco WCS Administration
You'll find this examination of the WCS really interesting. Learn how wireless enterprises are managed and monitored. Understand the benefits of WCS and the Locator Appliance.
|
00:20:43 |
|
|
|
WLAN Maintenance and Troubleshooting
This final nugget explores: maintaining the WLC, LWAP, and WCS; troubleshooting using visuals; common WLC and client issues; hidden node and exposed node; and several troubleshooting techniques and tools.
