If mobile network data volume grows 40 percent per year, you can see why new network platforms and spectrum are required. At that rate, usage nearly doubles every two years.
to boost network capacity by 10 times or more every 10 years at the very least, even including greater use of small cells that allow more intensive reuse of existing spectrum, plus better radio and modulation techniques.
Nor does it appear that any significant slowing of the growth rate (such as a reduction by half) is likely. The curve for data consumption between 2020 and 2030 looks almost identical to the Ericsson illustration of data growth between 2014 and 2022.
