Cisco's latest Visual Networking Index predicts that data traffic from wireless devices will surpass traffic from wired devices by 2015.
Cisco forecasts that by 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.
Moreover, the number of devices connected to IP networks will be twice as high as the global population in 2015, Cisco said. And it predicted that IP traffic per capita will reach 11 gigabytes per capita in 2015, up from 3 gigabytes per capita in 2010.
"A growing amount of Internet traffic is originating with non-PC devices," said Cisco's executive summary. "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."
Cisco predicts that global mobile data traffic will increase 26 times between 2010 and 2015, growing at a CAGR of 92 percent and reaching 6.3 exabytes per month by 2015.
