U.S. wireless data traffic grew by 123 percent from 2010 to 2011, from 388 billion megabytes to 866.7 billion MB, according to CTIA-The Wireless Association.
The wireless lobbying group's survey found a 43 percent increase in the number of active smartphones and other wireless personal devices, from 78 million in 2010 to 111.5 million last year.
"With almost 95 percent of these devices capable of transmitting wireless data, Americans' voracious appetite for anywhere and anytime mobile access is why the wireless industry needs more spectrum," the group said in a statement.
Some other tidbits from the report:
• A 7 percent increase in wireless subscriber connections, from 311 million in 2010 to 331.6 million last year.
• Number of active data-capable devices: 295 million, up from 270 million in 2010.
• Wireless-enabled tablets, laptops and modems: 20.2 million, a 49 percent increase from Dec. 2010.
• Minutes of Use: 2.296 trillion in 2011, up just 2 percent from 2010.
• Average local monthly wireless bill (including voice and data service): $47.00, virtually unchanged from 2010.
"Our survey shows yet again that we are choosing to have more than one wireless device, including smartphones, tablets and e-readers, which is why the wireless penetration rate is almost 105 percent," Steve Largent, president and CEO of CTIA, said in a statement.
