Via the Global Mobile Data Traffic Forecast Update, 2010–2015 from Cisco:
- Global mobile data traffic will increase 26-fold between 2010 and 2015. Mobile data traffic will grow at a compound annual growth rate (CAGR) of 92 percent from 2010 to 2015, reaching 6.3 exabytes per month by 2015.
- There will be nearly one mobile device per capita by 2015. There will be over 7.1 billion mobile-connected devices, including machine-to-machine (M2M) modules, in 2015-approximately equal to the world’s population in 2015 (7.2 billion).
- Mobile network connection speeds will increase 10-fold by 2015. The average mobile network connection speed (215 kbps in 2010) will grow at a compound annual growth rate of 60 percent, and will exceed 2.2 megabits per second (Mbps) in 2015.
- Two-thirds of the world’s mobile data traffic will be video by 2015. Mobile video will more than double every year between 2010 and 2015. Mobile video has the highest growth rate of any application category measured within the Cisco VNI forecast at this time.
- Mobile-connected tablets will generate as much traffic in 2015 as the entire global mobile network in 2010. The amount of mobile data traffic generated by tablets in 2015 (248 petabytes per month) will be approximately equal to the total amount of global mobile data traffic in 2010 (242 petabytes per month). The same will be true of M2M traffic, which will reach 295 petabytes per month in 2015.
- The average smartphone will generate 1.3 GB of traffic per month in 2015, a 16-fold increase over the 2010 average of 79 MB per month. Aggregate smartphone traffic in 2015 will be 47 times greater than it is today, with a CAGR of 116 percent.
