Duo partners for network modernization

Optus has selected Nokia Siemens Networks as a partner for its key network initiatives. The agreement includes modernization of the mobile network, refarming the 900 MHz GSM frequency band, and providing infrastructure and services for LTE (4G) rollout in Sydney and Perth. In addition, as part of this agreement, Nokia Siemens Networks is the sole LTE core provider for Optus.

"Spectrum is a scarce resource, so operators are seeking ways to make the best use of it. With this deal, Optus will re-use its existing spectrum to modernize its radio network and also offer 4G services cost-efficiently in one of the largest spectrum migration programs globally. Our mobile broadband offering, based on the Liquid Core and Liquid Radio architectures, will assist Optus in managing the dynamic capacity and technology demands in one of the most advanced mobile broadband markets," said Stephen McFeeley, Head of Australia and New Zealand, Nokia Siemens Networks.

"Our major mobile network initiatives, including network enhancements, U900 MHz spectrum migration program and 4G services rollout aim at providing the best possible experience for our customers. Nokia Siemens Networks is a key network partner in supporting these initiatives," said Günther Ottendorfer, Managing Director - Networks, Optus.

Nokia Siemens Networks is upgrading the Optus mobile network and deploying 4G using its Single RAN (radio access network) platform, based on its Flexi Multiradio Base Station. The company is also providing its Evolved Packet Core platform, including Flexi NS (Network Server) and Flexi NG (Network Gateway). Optus' LTE, GSM and 3G networks will be monitored, managed and optimized by Nokia Siemens Networks' unified network management system, NetAct.
