Nice writeup Natasha! On a quick scan.. One thing I'd consider mentioning: variability in performance based on location, time of day, number of users, etc. That is, just because you're on "4G" does not mean you'll reach XXMbps; users throughput is highly variable based on current network weather, which literally changes second to second. In some cases, where the networks are overloaded, the performance is poor/slow all the time -- e.g. 3G in country X has very different characteristics from 3G in country Y. ig On Sun, Sep 13, 2015 at 10:40 PM, Natasha Rooney <nrooney@gsma.com> wrote: > Hi all, > > I am working on the Network Information Roadmap document again for release > for TPAC.
