AT&T Mobility began operations in 2000 as a joint venture between the company and BellSouth Corporation and, in 2004, acquired AT&T Wireless Services, Inc. Upon its acquisition of BellSouth Corporation in 2006, AT&T Mobility became a wholly-owned subsidiary. In the United States, the company covers all major metropolitan areas and approximately 300 million people with its LTE technology. The company also provides 4G coverage using another technology (HSPA+). The company’s wireless network also relies on other GSM digital transmission technologies for 3G and 2G data communications. As of December 31, 2015, the company served approximately 128 million subscribers. Fixed Strategic Services: Fixed strategic services are the company’s major advanced business solutions. The company’s offerings use high-capacity digital circuits, and allow customers to create internal data networks and to access external data networks. Switched Transport services transmit data using switching equipment to transfer the data between multiple lines before reaching its destination. Dedicated transport services use a single direct line to transmit data between destinations. The company provides businesses voice applications over IP-based networks (Enhanced Virtual Private Networks). The company has built out its new IP/MPLS (Internet Protocol/MultiProtocol Label Switching) network, to supplement its IP-based product set, and eventually replace its older circuit-based networks and services. These products allow the company to provide highly complex global data networks. Additional IP-based services include Internet access and network integration, dedicated Internet and enterprise networking services. Network integration services include installation of business data systems, local area networking and other data networking offerings. Internet access services include a range of products, including access service, dedicated access, Web hosting, managed services, e-mail and high-speed access services.

These services are rapidly evolving to a cloud delivery model, providing customers with on-demand data storage and computing capabilities from a centrally-managed network (referred to as the cloud) accessible from various different devices and locations. Packet services consist of data networks using packet switching and transmission technologies, including traditional circuit-based and IP connectivity services. Packet services enable customers to transmit large volumes of data and are used for local area network (LAN) interconnection and inter-office communications. High-speed packet services are used extensively by enterprise (large business) customers. Enterprise networking services provide support from network design, implementation and installation to ongoing network operations and management for networks of varying scales, including LANs and virtual private networks. These services include applications, such as email, order entry systems, employee directories, human resource transactions and other database applications. The company also offers Wi-Fi service. Legacy Voice and Data Services: Voice services include traditional local and long-distance service provided to business and governmental customers, and wholesale access to the company’s network and individual network elements provided to competitors. The company also provides wholesale switched access service to other service providers. Its circuit-based, traditional data products include switched and dedicated transport services that allow business customers to transmit data at high speeds, as well as DSL Internet access.
