Came across this old presentation from the Cambridge Wireless FWIC 2015 by Plum consulting. I have written many posts on these topics but this is going to be a hot area for discussion for the coming months and year(s). In fact you might be seeing more on these topics in the next few months on this blog.
Here is the presentation from Plum embedded below.
