Indonesian mobile operator Telkomsel has awarded Siemens a contract to help build its 3G network. The three-year frame agreement covers the delivery of radio access networks and radio relay equipment for large parts of the W-CDMA network, as well as turnkey implementation and technical services. Telkomsel aims to cover the entire country with 3G network services, although in the first phase it will concentrate on the eastern regions, which are experiencing rapid economic growth and a fast rate of overall development. Siemens is supplying, installing and operating a 3G radio access network (RAN), including base stations and radio network controllers. For wide area transport, Siemens will also supply radio relay technology based on the Synchronous Digital Hierarchy (SDH) and Plesiochronous Digital Hierarchy (PDH) standards.
