GLENDALE, ARIZ., Jan. 29, 2015 — When football fans head to Glendale for pro football’s “Big Game” and the exciting pre-game events and festivities, they can expect to enjoy an enhanced mobile experience as they pull out their wireless device to share once-in-a-lifetime moments with friends and family.


AT&T has also deployed 10 Cell on Wheels (COWs) to accommodate expected increased wireless networkdemands from high concentrations of smartphone users in the greater Phoenix area for the Big Game. The COWs will help improve reliability and data speeds during the week leading up to the Big Game and on game day.

The temporary enhancements are part of AT&T’s ongoing efforts to prepare for and provide the best possible mobile experience during special events like the Big Game. With crowds expected to reach more than 100,000 people, AT&T’s network team has also enhanced 24 nearby cell sites.

These investments help to ensure that Arizona residents continue to enjoy the best possible experience over the AT&T network, whether at home, at work or on the go.  AT&T’s network has the nation’s strongest LTE signal, ** and AT&T also has the nation’s most reliable LTE network. ***

AT&T’s focus to deliver the best possible mobile Internet experience goes beyond 4G to embrace additional connection technologies. AT&T owns and operates more than 34,000 AT&T Wi-Fi Hot Spots at popular restaurants, hotels, bookstores and retailers, and provides access to more than 1 million 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 invested nearly $575 million in its Phoenix area wireless and wireline networks from 2010 through 2013. Over the past six years (2008 to 2013), AT&T invested more than $140 billion into its wireless and wireline networks, when you combine capital investment and acquisitions of spectrum and wireless operations. Over the past six years, AT&T has invested more capital into the U.S. economy than any other public company. In a September 2013 report, the Progressive Policy Institute ranked AT&T No. 1 on its list of U.S. “Investment Heroes.”
