Chuck Lukaszewski, from Aruba, talks at the Wireless LAN Professionals Conference about what's coming after 802.11ac. Well, it's a lot. So much about how we understand Wi-Fi to work is going to be turned on its head. Two-way MU-MIMO, infrastructure control/influence on clients, SMALLER channels, and more.
This is a must watch for anyone involved in wireless.
And here's a link to ALL the videos from WLPC. So many great sessions to watch.
