Fundamentals of Wi-Fi: Physics Always Wins

Tom Bridge and Chris Dawe Part of XW19


This workshop will provide an overview of the fundamentals of Wi-Fi networking, particularly as it relates to the Apple device ecosystem. Attendees will learn the fundamental principles of Wi-Fi, how Wi-Fi differs from the wired networking, and how Wi-Fi client devices and networks behave (or don’t) in the real world.


In the beginning–for most Mac Admins, anyway–there was the Airport Base Station, the Airport Card, and a wide-open spectrum…20 years later, it remains rare that one hears “The Wi-Fi at this conference is *great*!” Why?

In this workshop, Tom Bridge and Chris Dawe use their growing experience in the world of Wi-Fi to build on their 2015 and 2017 workshops to provide an understanding of a network technology that simultaneously manages to be ubiquitous, critical, and misunderstood.

This workshop will provide a basic introduction to Wi-Fi technology, describe basic Wi-Fi operations, provide an overview of Wi-Fi network design an troubleshooting, and discuss Apple-specific device behaviors that will make Wi-Fi network management more interesting than it was before.

In the course of the workshop, attendees will encounter the tools required for designing, building, and troubleshooting Wi-Fi networks, and receive a list of resources to continue their Wi-Fi education.

Topics covered in this workshop will include:

  1. Radio Frequency and Wi-Fi Technology Basics
  2. Basic Wi-Fi Client and Network Operations
  3. Introduction to Wi-Fi Network Design
  4. The Wi-Fi Engineering and Troubleshooting Toolkit
  5. Introduction to Network Security
  6. Apple Devices in the Wi-Fi World
