SACRAMENTO, Calif., Feb. 28, 2012 /PRNewswire/ -- AT&T* invested more than $400 million in its Sacramento area 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 575 wireless network upgrades in three key categories in the greater Sacramento area. These enhancements include:

• Activating nearly 15 new cell sites or towers to improve network coverage.
• Deploying faster fiber-optic connections to nearly 225 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 approximately 325 of these layers, or "carriers".

"Our goal is to deliver a network experience that mobilizes everything for customers," said Terry Stenzel, AT&T's Vice President/General Manager for Northern California and Northern Nevada.  "The ongoing investment we're making in the Sacramento area is designed to increase coverage and reliability, and to provide advanced services to our customers."

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.

"I applaud AT&T's commitment to continued investment in the Sacramento region," said Sanjay Varshney, CSUS Dean of the Business School. "This investment furthers California's focus on growing both large and small businesses by enabling them to communicate with newer, faster and more reliable wireless tools - vital to our state's economic recovery and future success," he said.

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., more than 290 hotspots in the greater Sacramento area 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.  In 2011, customers made 1.2 billion AT&T Wi-Fi Connections, with 486.9 million connections in the 4th quarter alone.
