Rakuten Mobile and NEC to build Open vRAN Architecture in Japan

Rakuten Mobile and NEC to collaborate in the field of 5G and jointly develop radio equipment for world's first highly secure cloud native 5G network

Tokyo, June 5, 2019 - Rakuten Mobile, Inc., the mobile network subsidiary of Rakuten Group, and NEC Corporation, a leader in the integration of IT and network technologies, today announced that the two companies have formed a partnership to build the world's first 5G open vRAN architecture in Japan. NEC has been selected to be the 5G network equipment provider for Rakuten Mobile's new and innovative network.

Through the partnership, Rakuten and NEC will jointly develop a 3.7 GHz massive MIMO 5G antenna radio unit (RU), which will be manufactured by NEC at its facilities in Japan. NEC's RU are ideal for 5G conditions as they are compact, lightweight and consume a low level of power, which reduces installation and operation costs.

Rakuten Mobile is currently building the world's first fully virtualized, end-to-end cloud-native mobile network. This innovative network is fully virtualized from radio access network to core and adopts 5G systems architecture from launch. In April 2019, Rakuten Mobile received approval from the Japanese Ministry of Internal Affairs and Communications for its 5G special radio station deployment plan and aims to launch 5G services in June 2020.

In building the network, Rakuten is nurturing an open ecosystem by actively engaging with industry leaders in crafting solutions. Rakuten and NEC are already working together on an end-to-end BSS/OSS solution to support the mobile network launch and subsequent operations. The expansion of the partnership with NEC to include 5G network equipment further builds upon Rakuten's vision of the disaggregation of hardware and software and true end-to-end virtualization of mobile networks, especially in radio access.

"We are very excited to partner with a network technology leader such as NEC in building the world's first 5G open RAN architecture here in Japan," said Tareq Amin, chief technology officer of Rakuten Mobile, Inc. "NEC's technology and expertise will allow us to not only cost-effectively create a highly secure, high quality 5G network, but by designing and producing the antennas in the local market, we look forward to contributing to the development of the Japanese telecommunications industry and economy."

"NEC is delighted to contribute to Rakuten Mobile's strategy for building the world's first fully virtualized, end-to-end cloud native mobile network," said Atsuo Kawamura, executive vice president and president of the Network Services Business Unit at NEC Corporation. "Going forward, NEC aims to drive the global expansion of virtualized network architecture with Rakuten Mobile."

With 5G, the Rakuten Group and Rakuten Mobile aim to not only improve convenience for their users, but also to utilize the technology in a variety of fields and create new business opportunities to solve social issues and support regional development.

NEC, with its focus on providing "Solutions for Society," will leverage its technological strengths and experience in network construction to support operators in building out their 5G networks and accelerate the expansion of its operations internationally.
