@Chris Kelly ,
Good News! WMM is part of process, rework/good reuse of physical channels is premisse... but..
The problem of high latency of my enterprise/BYOD is in my application...
We use iPad Kioks with our application and Android app for BYOD.
In particular case of iPad, we have experienced 30~100ms with always-on screen. Rare cases, have 200ms.
iOS have Power Management and priorize wifi traffic only necessary. If app not have any optimizations for "always on traffic", the latency increase 10x. SAP is very sensitive.
I explained to our devloper to take action to improve this. I wished him good luck.
