What you'll learn

Wireless networks are the backbone of modern connectivity, yet poorly designed and misconfigured WLANs lead to dead zones, dropped connections, and frustrated users. Understanding the architecture behind enterprise wireless is essential for any network professional expected to deploy, manage, or troubleshoot these environments.

In this course, WLAN Architecture, Components, and Configuration, you'll gain the ability to design, configure, and optimize enterprise wireless networks with confidence.

First, you'll explore WLAN infrastructure components and deployment topologies, including the differences between autonomous, lightweight, and cloud-managed access points, the role of wireless LAN controllers, and how split-MAC architecture divides responsibilities between APs and controllers.

Next, you'll discover how to configure essential WLAN settings such as SSIDs, VLAN mappings for traffic segmentation, band steering, and automatic RF management features including transmit power and channel assignment.

Finally, you'll learn how to explain wireless roaming mechanisms - including Layer 2, Layer 3, and 802.11r Fast BSS Transition, alongside QoS fundamentals such as WMM traffic priority queues that ensure voice and video traffic receives the treatment it demands.

When you're finished with this course, you'll have the skills and knowledge of WLAN architecture and configuration needed to deploy and optimize reliable, high-performance enterprise wireless networks.
