AT&T said its LTE network now reaches more than 300 million people across the United States, meaning that the operator has hit its target for the end of 2014 ahead of schedule.

“The strong performance we saw in our mobility business in the second quarter is continuing, not only because of our new service and device plans, but because more customers can get it all on a fast, reliable 4G LTE network that now covers more than 300 million Americans,” said Ralph Stephenson, AT&T chairman and CEO.

The U.S. operator also noted that wireless data traffic on its network has increased 2.5 times since November 2012 due to its customers’ growing desire for access to everything on the Internet, particularly video.

AT&T said it invested more than $140 billion into its wireless and fixed networks between 2008-2013, including acquisitions of spectrum and wireless operations.
