AT&T Wireless Upgrades Arizona Cell Network


Company Builds New Cell Sites, Boosts Capacity and Adds Fiber Optics
to Enhance Networks

PHOENIX, FEB. 22, 2012 — AT&T* invested more than $500 million in its Arizona wireless and wireline networks from 2009 through 2011 with a focus on improving the company’s mobile broadband coverage and overall performance of its networks.  Here is an example of how AT&T is showing new network upgrades in Phoenix what they are calling an AT&T Phoenix Microsite

During 2011, AT&T made more than 1,150 wireless network upgrades in four key categories in Arizona. These enhancements include:
  • Activating nearly 80 new cell sites or towers to improve network coverage.
  • Deploying faster fiber-optic connections to more than 675 cell sites. Combined with HSPA+ technology, these deployments enable 4G speeds**.
  • Adding capacity or an extra layer of frequency to cell sites – like adding lanes to a highway – with the addition of more than 300 of these layers, or “carriers”.
  • Upgrading nearly 100 cell sites to provide fast mobile broadband speeds.
AT&T also launched its new 4G LTE network in Phoenix.

“Our goal is to deliver a network experience that mobilizes everything for customers,” said Jennifer Biry, Arizona vice president and general manager, AT&T. “The ongoing investment we’re making in Arizona is designed to increase coverage and reliability, and to provide advanced services to our customers. Paired with our recent launch of our 4G LTE network in Phoenix, customers can use wireless technology to its full potential.”

CNN Money recently recognized AT&T for enhancing its wireless network. Last year, AT&T completed 150,000 network enhancements across the country, more than triple the year before, giving customers more capacity and faster speeds, as well as improving 3G dropped-call performance by 25 percent.

“More than ever, we use wireless communications to stay connected with family, friends and business colleagues,” said Glenn Hamer, President and CEO of the Arizona Chamber of Commerce and Industry. “I applaud AT&T’s continued investment in its wireless network to ensure Arizona residents and businesses can communicate and perform at optimal levels.”

AT&T plans to support the build or upgrade of thousands of cell sites nationwide to increase network speed, coverage and reliability for both mobile voice and broadband services. In addition, AT&T plans to install additional radio “carriers” at thousands of cell sites nationally, enabling new layers of spectrum capacity to carry larger volumes of mobile broadband traffic. Additional capacity helps support rising mobile data traffic volumes, which continue to increase at a rapid pace.

AT&T operates the nation’s largest Wi-Fi network*** with nearly 30,000 hotspots in the U.S. and provides access to nearly 190,000 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 recently launched "Focus: Phoenix", which provides visitors a peek into AT&T's wireless network enhancements made since the beginning of 2011.**** Enhancements include new cell sites, broadband speed upgrades, capacity upgrades and network connection upgrades. The site also provides a map of area AT&T stores, a map of area Wi-Fi hotspots, useful tips, a localized Twitter handle and device reviews.
