SAN FRANCISCO, Jan. 31, 2012 /PRNewswire/ -- AT&T* invested more than $6.8 billion in its California 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.

During 2011, AT&T made nearly 7,500 wireless network upgrades in four key categories in California. These enhancements include:

• Activating more than 120 new cell sites or towers to improve network coverage.
• Deploying faster fiber-optic connections to nearly 2,850 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 nearly 4,200 of these layers, or "carriers".
• Upgrading more than 300 cell sites to provide fast mobile broadband speeds.

AT&T also launched its new 4G LTE network in the San Francisco Bay Area, in Los Angeles and in San Diego on January 5.

"Our goal is to deliver a network experience that mobilizes everything for customers," said Fred Devereux, AT&T Region President – West.  "The ongoing investment we're making in California 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 the Bay Area, in Los Angeles and in San Diego, 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.

"To stay connected with friends, family and business, Californians use wireless communications now more than ever before," said Gene Hale, Chair, Greater Los Angeles African American Chamber of Commerce (GLAAAC).  "I applaud AT&T's continued investment to its wireless network and commitment to the communication needs of California's residents and businesses."

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. In 2012, AT&T plans to double its 4G LTE coverage.

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.
