Global mobile data traffic grew by over 75 percent in 2015, says a new report released by Cisco, the leader in networking. The report shows that at the end of 2015, global mobile data traffic reached 3.7 exabytes (billion gigabytes) per month, up from 2.1 exabytes per month at the end of 2014.
The Cisco Visual Networking Index forecast for 2015 to 2020 also said by 2020, over 71 percent of total IP traffic will originate with non-PC devices, including tablets, smartphones, and televisions, compared to 47 percent in 2015. By 2020, smartphones will generate 30 percent of total IP traffic, while PC’s total IP traffic contribution will fall to 29 percent.
More than half a billion (563 million) mobile devices and connections were added in 2015. Smartphones accounted for most of that growth. Global mobile devices and connections in 2015 grew to 7.9 billion, up from 7.3 billion in 2014.
Globally, smart devices represented 36 percent of the total mobile devices and connections in 2015; they accounted for 89 percent of the mobile data traffic. Average smartphone usage grew 43 percent in 2015 and the average amount of traffic per smartphone in 2015 was 929 MB per month, up from 648 MB per month in 2014.
Fourth-generation (4G) traffic exceeded third-generation (3G) traffic for the first time in 2015. Although 4G connections represented only 14 percent of mobile connections in 2015, they already account for 47 percent of mobile data traffic, while 3G connections represented 34 percent of mobile connections and 43 percent of the traffic. In 2015, a 4G connection generated six times more traffic on average than a nonâ€‘4G connection.
