AT&T announced on Wednesday that it will bring its advanced Long Term Evolution (LTE) mobile network five U.S. states this summer, including Dallas, Houston, Chicago, Atlanta and San Antonio.

LTE is the latest mobile network technology standard that is on its way to reaching requirements to be 4G, the fourth generation mobile networking standard. This should be met in later stages of development in the near future.

AT&T also said it plans to add another 10 or more markets in the second half of the year, and cover 70 million Americans with LTE by year-end.

"We also have plans to add 20 4G devices to our robust device portfolio this year, with some of those being LTE capable," John Donovan, AT&T Chief Technology Officer, said in a statement. "We're positioning to deliver a great mobile broadband experience in the near term with HSPA+ [ High Speed Packet Access Evolved ] and a growing LTE footprint."

AT&T said it has invested $75 billion in its wireless and wired networks over the last four years – more capital invested in the U.S. than any company in any industry – and plans to invest $19 billion more this year.
