As San Francisco residents we rightfully pride ourselves on being technology-savvy – and we demand more from our wireless networks. We are early adopters of smart phones, iPads, and new mobile technologies. We download apps, stream audio and video and like to have the option to consume media on the go as well as at home.

AT&T has experienced a 30,000% increase in mobile data traffic nationwide from 2006 to 2012.

San Francisco’s unique topography and tall buildings downtown are a challenge because they impede and obstruct wireless signals, causing dropped calls, sometimes inconsistent connectivity, and slower performance than consumers expect and demand.

That’s why AT&T is committed to expanding and improving our San Francisco wireless network infrastructure.

Why Should You Care?

Dropped calls and lack of wireless capacity is more than a nuisance it’s a public safety issue, a problem for small businesses and a real difficulty for families trying to stay connected.

Performance, Reliability and Speed

Upgrades to our San Francisco network will:

  • Minimize dropped calls
  • Improve network connectivity
  • Increase network speed
  • Deliver better coverage throughout the city

Investment, Union Jobs and Economic Catalyst

In order to bring faster more reliable 4G LTE networks to California communities, AT&T has invested more than $7 billion in its wireless and wireline networks in the state of California from 2010 through 2012.

These upgrades will help to give you the reliability and performance you expect from the nation’s #1 wireless carrier. 

We invested nearly $2.4 billion in San Francisco Bay area networks from 2010 through 2012.  Since January 2011, we have made more than 2,900 network upgrades in the San Francisco Bay area, including building 83 cell sites and boosting capacity to improve customers' mobile voice and broadband experience.

AT&T will employ skilled local union labor to implement this critical network upgrade.

The construction process comes at a time when jobs are needed in the city. AT&T is ready to invest the tens of millions of dollars in technology and skilled union labor necessary to improve its wireless network in San Francisco. AT&T is among the largest union employers in the nation and in California.

High speed access to the world’s ideas, information and marketplace can be a catalyst for finding employment, buying/selling goods, learning new skills and much more. A 4G LTE wireless infrastructure can easily become a stimulus for growth and commerce.

What is 4G?

4G is a wireless technology term meaning "Fourth Generation." 4G follows 3G as the latest addition to AT&T's mobile broadband network. When combined with enhanced backhaul, 4G means faster speeds, where data transfers take less time to complete.

4G LTE is capable of delivering mobile broadband speeds up to 10 times faster than 3G. 4G LTE is also more efficient than other mobile broadband technologies, providing responsive performance for customers when they need it most.

AT&T has upgraded the software of its nationwide mobile broadband network with HSPA+ which, with enhanced backhaul, enables speeds up to 4x faster than AT&T's already fast mobile broadband speeds. And now, AT&T is evolving to even faster 4G speeds with the launch of AT&T's 4G LTE technology in select markets, including areas of San Francisco.

What is LTE?

LTE stands for "Long Term Evolution" and refers to the ongoing process of improving wireless technology standards. LTE technology is the next step in increasing broadband speeds to meet the demands of users and the variety of content accessed over mobile networks.

Public Safety

74 percent of Americans who own mobile phones say they have used their hand-held device in an emergency and gained valuable help.

Small Business Survival

66% of small businesses surveyed said they could not survive — or it would be a major challenge to survive — without wireless technology.

Consumer Demand

More than 34% of consumers — 51% of low income consumers — rely solely on a wireless phone.


More than 91% of physicians use smartphones. By 2013, 60 million patients will be using remote patient monitoring devices.
