Extrapolations of current growth trends predict that networks need to be prepared to support up to a thousand-fold increase in total mobile broadband traffic by 2020.
This figure assumes a ten-fold increase in broadband mobile subscribers and up to 100 times higher traffic per user (beyond 1 GBytes per subscriber per day), with smart phones and similar connected devices experiencing the fastest growth.

You might wonder how networks can increase capacity by perhaps 1,000 times between now and 2020 or so. Nokia Siemen thinks it will take a combination of inputs, including 10 times more spectrum, plus an order of magnitude better spectral efficiency (10 times improvement) and then 10 times denser radio networks.
