Hi,

I don’t have a published analysis to cite, have done similar comparisons many times in various presentations. I could run that distribution from the Netradar database for 2014 and 2015, just need to give me the X buckets where to allocate the samples. 

Market analysis is a bit trickier, since measurements need to be mapped to a region somehow. IP address is one option if it can be trusted enough.
