Aruba’s 802.11ac In-Depth is 37 pages of 11ac goodness. I’ve read this document multiple times. There is something to be said when a technical document is easy on the eyes. When someone asks me for a 11ac quick read this is where I point them. Aruba technical documents provide some of the best detail, explanations and easy to understand graphical renderings. 


802.11ac is more then just faster WiFi. This document covers the fundamentals, usage models, channel bonding, and explains the complex coding and spatial streams.




Video and Display are the largest consumers of WiFi today and that trend will continue to grow. Netflix and Youtube are already seen on networks today as large bandwidth applications.
