It was announced by AT&T last September that they would be Launching their LTE/4G network in mid-2011, now we have some more details. AT&T has announced that it will be launching LTE this summers in five markets which are Houston,Dallas, Chicago, Atlanta and San Antonio. If you are not in these cities, still no worries as it will be coming to 10 more cities in the 2nd half of the year. The 10 more cities remain unnamed as of yet, but AT&T plans to give LTE coverage to about 70 million Americans by year’s end.

AT&T must be keeping an eye on Verizon wireless, who are leading this LTE competition. Verizon first announced 9 cities to receive LTE coverage on May 9th, and further announced 21 more cities to receive LTE coverage on May 23rd.

AT&T’s 4G Evolution

Dallas, Texas, May 25, 2011

By John Donovan, AT&T Chief Technology Officer

AT&T has delivered five mobile broadband speed upgrades in recent years, including our HSPA+ deployment last year. And average nationwide speeds on the AT&T network have increased – more than 40 percent over the past two years alone.

The next network evolution will arrive this summer with the addition of LTE in five markets – Dallas, Houston, Chicago, Atlanta and San Antonio. We plan 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.

We’re positioning to deliver a great mobile broadband experience in the near term with HSPA+ and a growing LTE footprint.

We’ve invested $75 billion in our wireless and wired networks over the last four years – more capital invested in the U.S. than any company in any industry. And we plan to invest $19 billion in our wireless and wireline networks and other capital projects this year. The investments we’ve made to evolve our mobile broadband network in recent years, plus what we have planned for the future, put our customers in position to benefit fully from a host of coming mobile broadband innovations.
