Data Evolution

I was reading this article from Ericsson from their Mobility November 2014 report and got to know some details on Mobile/Data trends and future of the Smart Phone with Data technologies like GPRS/EDGE/3G/4G/5G.

There was one point where they were discussing about data consumed in 2013, 2014 and what will happen in 2020. Before I go further please read regarding Data consumption terminologies at this link

In 2013 mobile data traffic was 2 EB/month and in 2014 it is 3.2 EB/month and in 2020 it will be 25 EB/month that is 40% increase in consumption.

Also number of smart phone devices with LTE/4G capabilities are going to increase and 3G devices will remain constant.

I would really like you guys to over this report once if you want to know about mobile phone and data statistics.
