While I do not like these "prediction/index" reports, I believe that when it comes from an organization such as Ericsson, with its huge managed services operation, it has a stronger base.
Ericsson published a new edition of its Mobility Report, that "reveals that mobile-data traffic will continue to grow significantly in the coming years, a trend driven mainly by video. Overall data traffic is expected to grow 12-fold by the end of 2018. Increasing usage is driven by continual growth in the amount of content available as well as the improved network speeds that come with HSPA and LTE development"
"LTE services will be available to about 60 percent of the world's population in 2018. We expect LTE subscriptions to exceed 1 billion in 2017, driven by more capable devices and demand for data-intensive services such as video .. Video makes up the largest segment of data traffic in networks, and it is expected to grow around 60 percent annually up until the end of 2018. Video consumption is on average 2.6GB per subscription per month in some networks"
Some figures from the report:
