Wireless Wide Area Network (WWAN) allows connectivity to a corporate infrastructure across AT&T's wireless network by using a cellular-enabled router combined with an Internet connection to connect to a data center and/or company headquarters. WWAN can also be used as an effective alternative to ISDN for backup connectivity (shown below) or as the primary solution in situations where wired networks are not available or feasible, such as outdoor or temporary locations.

Examples of a WWAN Solution:

• Mobile Internet connectivity on a bus via Wi-Fi
• Police and emergency services in-vehicle solutions
• Data-enabled mall kiosks
• Backbone redundancy for small to midsized offices

Why Would a Business Want Wireless WAN Connectivity from AT&T?

Fast and Flexible - A WWAN solution is faster to install than traditional wired lines. Plus, if there is a need for connectivity in a temporary location or new location, WWAN offers the flexibility to relocate quickly and easily.

Backup Connectivity - WWAN is an ideal backup solution for mission-critical data. If a wired line outage occurs, WWAN offers a diverse, cost effective means of redundancy for data applications.

Security - With a WWAN solution from AT&T, a business can leverage their existing security infrastructure as well as choose from a number of connectivity options by leveraging AT&T's Commercial Connectivity Service Portfolio. The Commercial Connectivity Service Portfolio provides flexible configurations, thus giving WWAN-enabled locations reliable network-to-network connections to enterprise data resources.

Economical - WWAN connectivity may be less expensive than alternative wired solutions for telemetry and backup applications. WWAN is also a cost effective means of primary connectivity for low-bandwidth applications such as:

• Point of sale locations
• Kiosks and ATMs
• Vehicles
• Remote measurement and monitoring equipment
• Temporary locations
• Branch offices
