Course Overview

Course in a Nutshell

Using lecture interspersed with lab work, this workshop will help you acquire a thorough understanding of 802.11 operations, with a focus on delivering a rich voice, video and data user experience. You will learn about the physical layer and the challenges of operating in unlicensed spectrum. You will also gain an in-depth understanding of how to connect to a Wi-Fi network and send data. Covered are MAC frame format, 802.11e QoS, 802.11n high throughput, and 802.11ac very high throughput.

The lab work will require the participants to bring Windows based laptops to the classroom, and it will use the spectrum analyzer Metageek Chanalyzer 4 and the packet analyzer Wireshark.
