Cisco’s annual Global Mobile Data Traffic Forecast makes some interesting (some may say frightening) predictions, including the fact that the number of mobile-connected devices will exceed the world’s population sometime this year.

The study, which looked at worldwide mobile networks, also found mobile data traffic went up 133 percent in 2011 and will likely grow another 110 percent this year.

It’s not a surprising trend, given all the mobile devices on the market — the number of wireless subscriber connections in the US already outnumbers our population.

As for who’s using all that data, blame those with Android devices — they use 29 percent more than Apple’s iOS devotees.

But overall, Cisco reports that by 2017, some 60 percent of mobile users will gobble up more than a gigabyte of monthly mobile data, compared to the only 0.5 percent who did last year.
