The AT&T network includes extensive wireless and wired access
capabilities, as well as one of the world's most advanced and powerful IP
The AT&T global backbone network carries 18 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 16.7 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 163 countries over 3,800 service nodes.
- 290,000+ managed MPLS ports for customers.
- 38 Internet data centers across the globe.
- 928,000 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
more than 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.
- 16.7 million high speed Internet subscribers.
- Wi-Fi access at more than 90,000 hot spots spanning countries around the world (including company-owned and third-party roaming locations).
We're constantly working to deliver new capabilities and applications via our access network.
