Optus has selected Nokia Siemens Networks to modernize its mobile network, refarme the 900 MHz GSM frequency band, and provide infrastructure and services for LTE rollout in Sydney and Perth. In addition, Nokia Siemens Networks is supplying LTE core to Optus.

As part of this agreement, Nokia Siemens Networks is upgrading the Optus mobile network and deploying 4G using its Single RAN (radio access network) platform, based on its compact, 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.

The company will also provide Optus with a range of services, including network implementation, spectrum refarming, radio planning, optimization, project management, and care including spare part management, software maintenance, third-party software support and training. Some of these services will be delivered remotely through Nokia Siemens Networks' Global Delivery Centers. Nokia Siemens Networks will also implement its In Building Solution (IBS) that enables reliable mobile broadband connectivity by significantly improving network capacity and coverage inside buildings.
