In the first half of 2012, AT&T invested nearly $100 million in its Wisconsin wireless and wired networks.

Network upgrades include activation of new cell sites or towers to improve network coverage, deploying faster connections to enable 4G speeds, and adding spectrum capacity to support additional traffic.

First-half upgrade highlights include:

• New cell sites in Minocqua and Shiocton.
• New Distributed Antenna Systems (DAS) at West Towne (Madison), Mayfair (Milwaukee) and Brookfield Square (Milwaukee) malls, Milwaukee's ballpark and Mitchell International Airport.
• Expansion of mobile Internet service in Manitowoc, Aniwa, Cecil, Gillet, Marion, Tigerton, Pulaski and Shawano.
• Added capacity around the Wisconsin State Fair to bolster coverage for guests. In addition, capacity was also added to 52 cell sites in the Milwaukee area since January 2012.

AT&T network upgrades in Wisconsin also include deployment of new Wi-Fi hot spots and backbone network connections.

"We're working to build a 4G network that's smarter and better to provide our customers with a superior mobile Internet experience," said AT&T Wisconsin State President Scott VanderSanden. "The ongoing investment we're making across Wisconsin is designed to increase 4G coverage, reliability and speed. We also continue to invest in technologies like Wi-Fi and DAS to help provide customers with the best connections when they want it, whatever they're doing."

AT&T's innovation and investment has resulted in the nation's largest 4G network, covering 275 million people with ultra-fast speeds and a more consistent user experience. AT&T is the only U.S. service provider to deploy two compatible 4G technologies, LTE and HSPA+, to deliver more speed to more customers.

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** among wireless carriers with more than 30,000 hotspots in the U.S., and provides access to nearly 225,000 hotspots globally through roaming agreements. 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 System (DAS) networks, 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."
