This summary info will provide you a general view on mobile data traffic growth.
The original document is released by Cisco with the name Global Mobile Data Traffic Forecast 2014–2019.
Here, I tried to make a little summary. You can also find the original document link at the end of this post.
The Mobile Network in 2014
• Global mobile data traffic grew %69 in 2014.
• Last year’s mobile data traffic(30 exabyte) was nearly 30 times the size of the entire global Internet in 2000 (1 exabyte).
• Mobile video traffic exceeded %50 of total mobile data traffic for the first time in 2012. It was %55 by the end of 2014.
• Almost half a billion (497 million) mobile devices and connections were added in 2014
• In 2014, on an average, a smart device generated 22 times more traffic than a non-smart device.
• Mobile network (cellular) connection speeds grew %20 in 2014. (Average downstream speed in 2014 was 1,683 kbps, up from 1,387 kbps in 2013)
• In 2014, a 4G connection generated 10 times more traffic on average than a non-4G connection. Although 4G connections represent only %6 of mobile connections today, they already account for %40 of mobile data traffic.
• Average smartphone usage grew %45 in 2014 (563 MB to 819 MB per month).
• Per-user iOS mobile devices (smartphones and tablets) data usage marginally surpassed that of Android mobile devices data usage
• In 2014, %27 of mobile devices were potentially IPv6-capable.
The Mobile Network Through 2019
• Global mobile data traffic will increase nearly tenfold between 2014 and 2019.
• Monthly global mobile data traffic will surpass 24.3 exabytes by 2019.
• By the end of 2014, the number of mobile-connected devices will exceed the number of people on earth, and by 2019 there will be nearly 1.5 mobile devices per capita. (11.5 billion mobile-connected devices by 2019, population will be 7,6 billion)
• Mobile network connection speeds will increase more than twofold by 2019. The average mobile network connection speed:
o 1.7 Mbps in 2014
o 2.0 Mbps by 2016
o 4.0 Mbps by 2019
• By 2019, 4G will be %26 of connections, but %68 of total traffic.
• By 2019, more than half of all devices connected to the mobile network will be “smart” devices.
• By 2019, %50 of all global mobile devices could potentially be capable of connecting to an IPv6 mobile network
• Nearly three-fourths of the world’s mobile data traffic will be video by 2019(%72 of total mobile data traffic)
• The average smartphone will generate 4.0 GB of traffic per month by 2019, a fivefold increase over the 2014 average of 819 MB per month.
• The Middle East and Africa will have the strongest mobile data traffic growth of any region with a %72 CAGR.
