Dallas-based AT&T is racing to keep up with surging demand for mobile data services.
The company is coping with surging demand for its mobile services, thanks to popular products such as Apple's iPhone and iPad. AT&T is the exclusive service provider for those devices.
"It's a daunting task," said John Donovan, AT&T's chief technology officer.
Donovan said data traffic on AT&T's network is up 5,000 percent in just three years. The company currently supports roughly half of all mobile data traffic in the United States.
Critics say AT&T hasn't done enough to keep up.

The goal is to keep up with consumers who can't seem to get enough of mobile services.
"It's become a never-ending circle of trying to play catch-up," Kaufman said.
But AT&T is vowing to get ahead of the curve.
"We're building as much and as fast as we can," Donovan said.
