The AT&T network includes extensive wireless and wired access capabilities, as well as one of the world's most advanced and powerful IP backbones.

The AT&T global backbone network carries 16.8 petabytes of data traffic on an average business day — the equivalent of more than 2.6 megabytes of data each business day for every man, woman and child on the planet — to nearly every continent and country, with up to 99.999 percent reliability.

Our backbone network carries a full range of IP-based services, including wireless data, business video, data and voice services, private line and wavelength traffic, as well as IP-based residential services and Internet access for AT&T's 16.3 million DSL and AT&T U-verse service customers.

Our network also incorporates Multiprotocol Label Switching (MPLS), which supports a full range of applications over a single IP network infrastructure with the highest levels of service quality.

To stay ahead of the ever-increasing demand for online video, photos, music and IP-based business applications, we recently switched on the nation's first coast-to-coast IP/MPLS network using new-generation routing technology that carries data at 40 Gbps. More than 40 percent of the IP traffic carried over the company's backbone network rides on this new-generation platform.

The AT&T global backbone network includes:

• MPLS-based services available to 155 countries over 3,800 service nodes.
• 270,000+ managed MPLS ports for customers.
• 38 Internet data centers across the globe.
• 888,600 worldwide fiber route miles.

Our industry-leading wireless network includes:

• Our fully digital voice and data network, with GSM/GPRS (Global System for Mobile communications/General Packet Radio Service) infrastructure that covers 100 percent of our service area — more than 3.8 billion people in 200+ countries.
• Third-generation, or 3G, wireless broadband service, available today in nearly 350 U.S. major metropolitan areas.
  • Wireless laptop users are enjoying faster broadband uplink speeds thanks to our current deployment of High Speed Uplink Packet Access (HSUPA) technology. AT&T completed the first High Speed Uplink Packet Access (HSUPA)-enabled network in the United States in June 2008.
• Superior spectrum availability in the nation's top 100 markets.

Our U.S. wired network capabilities encompass:

• 55.6 million access lines.
• 16.3 million high speed Internet subscribers.
• Wi-Fi access at more than 80,000 hot spots spanning countries around the world (including company-owned and third-party roaming locations) — with the addition of approximately 7,000 Starbucks locations.

We're constantly working to deliver new capabilities and applications via our access network.
