Tellabs multiservice mobile solution a clear choice for Claro
Claro Argentina, Paraguay and Uruguay save costs by optimizing network infrastructure with the Tellabs 8600 Managed Edge System

Naperville, Ill. — The Tellabs® 8600 Managed Edge System enables mobile operators to provide current and future 2G, 3G, and 4G mobile and data services to users cost-effectively. The system saves capital and operating costs by integrating legacy and new technologies, including PDH, SDH, ATM, FR, Ethernet and IP, on a single platform. Mobile operators can protect investments in current infrastructure while migrating to newer technologies to meet user demand.

To deliver clearly superior mobile service, Claro Argentina, Paraguay and Uruguay, subsidiaries of América Móvil, use the Tellabs 8600 system. The system enables Claro to offer mobile users broadband Internet and crystal-clear voice with the best coverage in Argentina, Paraguay and Uruguay.

“Tellabs has been our trusted provider for years, and its wireless backhaul solution meets all of our expectations,” said Fernando del Rio, commercial director of Claro. “The platform gives us flexibility to offer carrier-class services to our customers while saving operating and capital costs.”

Clear choice for the future
Claro already uses the Tellabs® 8100 Managed Access System and Tellabs® 8000 Network Manager, and has for many years. Now, getting the network ready to meet new user requirements is easy. Tellabs simply integrated the Tellabs 8600 system into Claro’s network while managing the entire network with the Tellabs 8000 manager—a product the company already uses. The Tellabs 8000 manager has all the tools the operator needs. Claro can use it to bring operating efficiency to its network and save capital expenses.

“Tellabs provides Claro a clear path to evolve its mobile networks to meet the growing needs of users, while remaining profitable,” said Tarcisio Ribeiro, vice president of sales for Tellabs' Latin America and Caribbean region. “We develop our systems in close cooperation with our customers to ensure we fulfill even their most stringent requirements.”
