Nokia Siemens Networks to provide LTE upgrade in Japan

On Monday, Nokia Siemens Networks announced that Softbank Mobile Corp is upgrading its mobile broadband network across Japan using its technology and services. Softbank has selected Nokia Siemens Networks to supply, deploy and integrate its 4G, FDD-LTE (Frequency Division Duplex – Long Term Evolution) network, which is expects to have running by the fall of 2012.


Under a separate contract, Nokia Siemens Networks (Espoo, Finland) will also expand Softbank’s (Tokyo) HSPA+ network to enable new services using the recently allocated 900 MHz frequency band.


“In moving to 900MHz, a frequency used for HSPA+ around the world, Softbank Mobile will be able to effectively expand its HSPA+ network coverage, capacity and device portfolio,” says Takayuki Kanda, head of the SoftBank customer team at Nokia Siemens Networks


Nokia Siemens Networks will deploy its Flexi Multriradio Base Station for both Softbank’s FDD-LTE network and HSPA+ network expansion. It will also provide backhaul transport with its FlexiPacket Microwave platform. Support services for Softbank Mobile’s network deployment include network implementation and system integration, while for the HSPA+ network expansion, Nokia Siemens Networks will also provide site acquisition, making it a turnkey project, says the company.


Nokia Siemens Networks will also update its network management system NetAct to enable consolidated monitoring, management and optimization of the operator’s LTE and HSPA+ networks.


 “Softbank Mobile is witnessing a major upsurge in subscriber numbers with now over 28 million customers,” says Junichi Miyakawa, executive vice president, director and CTO at Softbank Mobile.
