DETROIT, Jan. 4, 2013 /PRNewswire/ -- As part of its continuing network investment and ongoing 4G LTE rollout, AT&T* has upgraded three mobile Internet cell sites in Ann Arbor, Beverly Hills and Birmingham to expand AT&T 4G LTE coverage for area residents and businesses.

AT&T 4G LTE is the latest generation of wireless network technology and provides several benefits for local residents, including faster mobile Internet speeds —up to 10 times faster than 3G, improved performance and innovative new 4G LTE-compatible devices.

AT&T launched its ultra-fast 4G LTE network in Detroit in September 2012. The new cell sites are one part of AT&T's ongoing efforts to expand 4G LTE coverage and to drive investment and innovation to deliver the nation's best, most advanced mobile Internet experience for customers.

"Our goal is for our customers to have an extraordinary experience, and they'll be able to download, upload, stream and game faster than ever before on our 4G LTE network," said Jim Murray, president, AT&T Michigan. "As part of the Metro Detroit community, we're always looking for new opportunities to provide enhanced coverage, and our investment in the local wireless network is another way we're accomplishing that."

AT&T's 4G Network
AT&T's innovation and investment have resulted in the nation's largest 4G network, covering 275 million people with ultra-fast speeds and a more consistent user experience. That's coverage in 3,000 more 4G cities and towns than Verizon.

AT&T is the only U.S. service provider to deploy two compatible 4G technologies to deliver more speed to more customers. Our 4G LTE network delivered faster average download speeds than any of our competitors in PCWorld's most recent 13-market speed tests.

AT&T's 4G LTE network delivers speeds up to 10 times faster than 3G**, as well as multiple innovations that optimize the network for performance. Our network's radio components are placed close to the antenna at most cell sites, instead of inside the base station, which helps minimize power loss between the base station and antenna and, in turn, improves the performance of our 4G LTE network. The network also is designed with its core elements distributed across the country, which helps reduce latency, or the delay when using the Internet, because your request isn't traveling as far.

Even as AT&T continues to expand its 4G LTE coverage in 2013, customers can get 4G speeds outside of 4G LTE areas on our 4G HSPA+ network,  unlike competitors, where customers fall back to slower 3G technologies when outside of LTE coverage.

AT&T's focus to deliver the best possible mobile Internet experience goes beyond 4G to embrace additional connection technologies. AT&T operates the nation's largest Wi-Fi network*** including more than 30,000 AT&T Wi-Fi Hot Spots at popular restaurants, hotels, bookstores and retailers across the country.  Most AT&T smartphone customers get access to our entire national Wi-Fi network at no additional cost, and Wi-Fi usage doesn't count against customers' monthly wireless data plans.

AT&T also is a leading developer of Distributed Antenna Systems, which utilize multiple small antennas to maximize coverage and speed within stadiums, convention centers, office buildings, hotels and other areas where traditional coverage methods are challenging. 

Over the past five years, AT&T invested more than $115 billion into operations and into acquiring spectrum and other assets that have enhanced our wireless and wired networks. Since 2007, AT&T has invested more capital into the U.S. economy than any other public company. In a July 2012 report, the Progressive Policy Institute ranked AT&T No. 1 on its list of U.S. "Investment Heroes."
