The amount of videos, audio and emails sent via laptops, smartphones and tablets in 2011 exceeded predictions, and the wireless industry is struggling to keep up.
Cisco Systems has released an annual report showing that wireless data traffic rose by 133% in 2011 - 2% more than had been anticipated.
As more and more people watch mobile video and use tablets, global wireless networks have been under more pressure than ever.
Wireless carriers, equipment suppliers and software developers use Cisco's Visual Networking Index to predict sales of their products.
Suraj Shetty, vice-president of service provider marketing at Cisco in San Jose, California, said: "Mobile data traffic will continue to explode. This is a trend we don't see slowing down."
Cisco has predicted mobile data growth will climb by 110% this year, with traffic increasing 18-fold by 2016 to reach 10.8 exabytes per month.
