I’m incredibly grateful to AUC and Tony Gray for their invitation to Chris Dawe and I to present our workshop, Fundamentals of Wi-Fi: Physics Always Wins. While we’re not making our full slides available for this talk, we did want to provide some external-facing documentation for our talk that gives you some of the key materials that we used while making this talk.
How to Reach Us
Books & Printed Material
Sometimes, you need to start with printed materials.
The Wireless LAN Professionals organization is the certifying authority for professional WLAN Engineers, and their mission includes training and certification. the CWNA 107 Study Guide (and the now discontinued Sybex volume for the 106 exam that preceded it) is an excellent resource to understanding much of the Wireless sphere.
