Roaming behavior of mobile devices on Wi-Fi and real-time troubleshooting - Not all mobile devices are created equal and not all agree on best ways to roam when connected to Wi-Fi networks. In addition to simple speeds and feeds, rate vs. range characteristics of mobile devices influence the experience of users. Join us to learn more about troubleshooting a wide range of device connectivity issues and Aruba Wi-Fi configuration options like ClientMatch, which can vastly improve device roaming behavior.

There seems to be an error on slide 23. It claims that the 802.11 standard mandates that beacons are "sprayed out" at all data rates. This isn't true. A quick packet capture using a protocol analyzer quickly revealed that beacons are broadcasted once at a single rate every beacon interval (100ms by default).
In our environment where we did the capture, beacons were broadcasting at 12mbps, once every 100ms. You can see the data rate at which they were transmitted in the Radiotap field of the attached capture.
We have set the basic rates as 12/24 and supported as 12+ (also visible in the packet capture). We did not set the beacon rate - this was left as default in the SSID profile.
Thanks to my colleague Kyle Dimmick for doing the packet captures and reviewing the data with me.
