The Cisco Visual Networking Index: Forecast and Methodology, 2010–2015 predicts that by 2015, majority of IP traffic will come from wireless devices, not wired ones, by 2015. Below are the findings and predictions from the Cisco report.
Traffic from wireless devices will exceed traffic from wired devices by 2015. In 2015, wired devices will account for 46 percent of IP traffic, while Wi-Fi and mobile devices will account for 54 percent of IP traffic. In 2010, wired devices accounted for the majority of IP traffic at 63 percent.
A growing amount of Internet traffic is originating with non-PC devices. In 2010, only 3 percent of Internet traffic originated with non-PC devices, but by 2015 the non-PC share of Internet traffic will grow to 15 percent. PC-originated traffic will grow at a CAGR of 33 percent, while TVs, tablets, smartphones, and machine-to-machine (M2M) modules will have growth rates of 101 percent, 216 percent, 144 percent, and 258 percent, respectively.
Busy-hour traffic is growing more rapidly than average traffic. Busy-hour traffic will increase fivefold by 2015, while average traffic will increase fourfold. During an average hour in 2015, the traffic will be equivalent to 200 million people streaming high-definition video continuously. During the busy hour in 2015, the traffic will be equivalent to 500 million people streaming high-definition video continuously.
Global IP traffic has increased eightfold over the past 5 years, and will increase fourfold over the next 5 years. Overall, IP traffic will grow at a compound annual growth rate (CAGR) of 32 percent from 2010 to 2015.
In 2015, the gigabyte equivalent of all movies ever made will cross global IP networks every 5 minutes. Global IP networks will deliver 7.3 petabytes every 5 minutes in 2015.
Video-on-demand traffic will triple by 2015. The amount of VoD traffic in 2015 will be equivalent to 3 billion DVDs per month.
Globally, mobile data traffic will increase 26 times between 2010 and 2015. Mobile data traffic will grow at a CAGR of 92 percent between 2010 and 2015, reaching 6.3 exabytes per month by 2015.
Global mobile data traffic will grow three times faster than fixed IP traffic from 2010 to 2015. Global mobile data traffic was 1 percent of total IP traffic in 2010, and will be 8 percent of total IP traffic in 2015.
IP traffic is growing fastest in Latin America, followed closely by the Middle East and Africa. Traffic in Latin America will grow at a CAGR of 50 percent between 2010 and 2015.
Because people are using mobile devices more than their wired devices, we will see even more applications for smartphones and tablets for mobile payments, shopping, gaming, and other ways that these devices use location and context.
