Global mobile data traffic grew 70% in 2012 and is projected to increase 13-fold by 2017 according to Cisco's Visual Networking Index. Key trends driving this growth are the proliferation of diverse mobile devices such as smartphones, tablets, and machine-to-machine modules which generate significantly more data than basic phones. Average traffic per device is also increasing rapidly as users consume more mobile video and content on higher-speed 4G networks. By 2017 over two-thirds of global mobile data traffic will be for video.
