AT&T Business Solutions has announced a three-year agreement with mining and natural resources company Cliffs Natural Resources to enhance its global network and provide enterprise mobility through wireless services.

Under the terms of the contract, AT&T will establish a virtual private network (VPN) to support numerous data and voice applications among 20 locations worldwide.

By enhancing efficiency and reliability, this network provides cost efficiencies and positions Cliffs for the future use of advanced technology applications, such as video and conferencing.

AT&T Business Solutions is also keeping Cliffs employees connected in the office and off-site with wireless service and handsets. These employees will experience the ease and flexibility of being connected on a global wireless network, giving them immediate access to each other and corporate resources.

According to AT&T, Cliffs’s portfolio of solutions will be consolidated with AT&T Business Network. Cliffs will also have access to the AT&T BusinessDirect web portal, which provides immediate access to real-time information on network performance, electronic billing and ordering systems.

John Kory, director of IT operations and infrastructure for Cliffs Natural Resources, said: Cliffs Natural Resources, much like AT&T, has a long history and dynamic future because of our commitment to leveraging leading technology to improve operations and customer experience. AT&T is keeping us connected and positioning our business for greater momentum moving forward.
