Chapter 4: Detecting Physical Issues, Wireless Architectures, and Virtualization

Computer networking has evolved tremendously over the past decade. Today, in order for networking to adapt to the ever-changing landscape of the internet, companies such as Cisco not only produce physical network devices and security appliances but also work with virtualization and cloud technologies.

We live in an age where smart technologies allow people to be more connected digitally than ever. Wireless networks need to be able to support the vast number of connected wireless devices and, most importantly, be able to efficiently transport data between a wired network and a wireless one, and vice versa.

Throughout this chapter, you will learn about physical issues on a network, principles of wireless technologies, and how to transmit messages between devices. Additionally, you will learn how to access and deploy a Cisco Wireless LAN Controller (WLC) on a network and implement basic configurations...
