Network: Robust Network and Security

A Better Network Means Better Business

The AT&T Network

The AT&T Network covers over 300 million people and is growing, creating a solid platform to deliver services and solutions. For mobility it offers the nation's fastest 3G network and with the deployment of 7.2Mbps markets, the nation's fastest network is getting faster!

Our network is built on the worldwide GSM standard—the most widely deployed network standard in the world with 89% share, or over 3.6 billion subscribers worldwide. GSM provides:

• Economies of scale—wider range and lower cost of solutions and devices
• Global compatibility—more international roaming potential
• Ease of integration with emerging/new standards like LTE (Long Term Evolution)

AT&T is spending over 19 billion dollars in 2009, 5 billion each year for the past five years on the mobility network. Here's what AT&T is doing to improve voice and data communication for 2009:

• Nearly 2,000 additional 3G cell sites
• Over 20 new major metro markets for 3G
• Announcement of 6 major markets for faster 3G speeds/7.2Mbps, including: Charlotte, Chicago, Dallas, Houston, and Los Angeles and Miami
• A national deployment of 850MHz spectrum for 3G to provide improved in-building penetration and overall improved coverage
• Plans to test and deploy the next generation of wireless standards—LTE (Long Term Evolution) promising faster speeds, but still in the GSM standards as our 2G and 3G technology

Fastest 3G in the Nation

Built on the global standard for wireless, the AT&T 3G network delivers the high speed and coverage your business needs to keep work flowing when you're on the road. High Speed Packet Access (HSPA) provides for fast speed for our mobility customers over earlier 3G/UMTS releases. Using 7.2Mbps, customers with capable LaptopConnect products or phones, like the iPhone 3G S, can experience the 7.2 speeds in coverage areas.

With the enhanced 3G network, you'll enjoy even better mobile broadband access to email, Internet and other applications.

• Available in most major metropolitan areas, providing typical download speeds of 700 Kbps to 1.7 Mbps and typical upload speeds of 500 Kbps to 1.2 Mbps on compatible devices for our current 3G network*
• Additional faster speeds available for 7.2 capable devices, depending on network conditions and availability**
• The only 3G technology that supports simultaneous voice and data with one device - your work doesn't stop when you need to talk
• Wireless service is available in select metropolitan markets
• Supported by AT&T Communication Manager software for LaptopConnect products

Wi-Fi another option for wireless users

We offer over 25,000 U.S. hotspots at no additional charge to your AT&T data plan***; including locations such as: Starbucks stores, Barnes and Noble stores, airports and participating McDonald’s restaurants.
