What do "your" WiFi clients support?
The need to know "what my clients support" is common. For example, before enabling a certain frequency or feature on your WLAN, like channel 144 or 802.11w. Other times, you'd like to know what the percentage of 1/2/3 Spatial-Stream or MU-MIMO capable devic...

Hoping to start some conversation on Channelization & how Overlapping BSS (OBSS) impacts performance. The general idea is here: http://www.mikealbano.com/2015/10/channelization-obss-impact.html

Interpreting & Graphing ARM Counters
The topic of "do you trust RRM" is often discussed. The most typical answer is: "Yes, if I understand it." I know I've personally spent numerous hours blaming RRM for a questionable Dynamic Channel Assignment (DCA), and I'm  usually  wrong. For the purpose ...

I've created a living document for Client DFS support. If you have a client not on the list, consider letting me know if it supports DFS. Easiest way is to look at the "Association Request" frame, under "supported channels". Share your results here, or email me or @mike_albano

+mrncciew​ brought this to my attention in a recent blog post: http://mrncciew.com/2014/11/01/nbase-t-2-55g-over-cat5e6/ I've been banging the drum of >1Gb in a single cell is just not going to typically be an issue, for a while now. Even in wave 2 .11ac. I'm wondering what others are seeing in their highest density wave 1 deployments, like lecture halls? What's the max TCP/UDP you are seeing on your uplinks? More capacity, not necessarily more speed with MU-MIMO, will certainly increase uplink utilization, but I'm wondering what the "typical" vs. "HD" WiFi cells will look like in the coming years. Thoughts?

HD-WiFi, Co-Channel, and Noise Floor
So you walk into a large public venue (LPV), Stadium, or Lecture Hall and pull up your favorite mobile WiFi scanner app and there it is; CCI out the yang. Way more Co-Channel Interference/Contention (CCI, or CCC depending on which semantics camp your in) th...
