Fujitsu and NTT make strategic business alliance for next-generation communication “6G”

Fujitsu and NTT announced on April 26 that they will form a strategic business alliance for the “6G (Beyond 5G: 6th generation communication)” era, which will be the next-generation communication infrastructure. NTT is advocating “IOWN (Innovative Optical and Wireless Network),” which is a concept for next-generation networks and information processing infrastructure, and positions photoelectric fusion technology as a key technology to realize it. Through this alliance, the company intends to accelerate the realization of photoelectric fusion technology and utilize it not only in communication equipment but also in the computing field, aiming to innovate communication technology for the Beyond 5G era. In addition, Fujitsu is in full swing on research and development related to next-generation communication infrastructure, such as the establishment of the “IOWN / 6G Platform Development Office” on April 1 for the purpose of IOWN concept and technological development in the 6G era. The results obtained through this alliance will be utilized in solution services and platforms, and will be proposed to a wide range of customers in the manufacturing industry, distribution, retail, and medical fields.

Mr. Jun Sawada (left), President of NTT, and Mr. Takahito Tokita, President of Fujitsu, said at this press conference, Mr. Jun Sawada, President of NTT, said, “This alliance is NTT’s optical technology, wireless technology, and operational know-how. , Combining Fujitsu’s world-class computing technology and the strength of integrating various technologies, and utilizing joint research and its results, promote global open innovation and realize a low-energy and highly efficient digital society Aim for. ” Fujitsu President Takahito Tokita said, “In the future, DX (digital transformation) will progress in all fields and sites, and the value of data distributed between different industries and systems will increase. Process huge amounts of data in the ultimate real time. In order to achieve a discontinuous breakthrough and pursue cutting-edge technology that has a global impact, it is essential to establish a strong research and development system with NTT. We thought that it was the optimal solution and reached an alliance. We would like to contribute to the realization of a future digital society. ” The contents of the alliance are “device innovation” that establishes photoelectric fusion manufacturing technology, “communication technology innovation” by promoting open communication technology, and “computing innovation” by realizing low power consumption high-performance computing. It becomes 3 points. In “Device Innovation,” NTT Electronics (NEL), which develops and manufactures hardware products that utilize NTT’s advanced device technology, acquired a 66.6% stake in Fujitsu Advanced Technology (FATEC), which has semiconductor mounting technology. Will be changed to “NTT Electronics Cross Technology”, and from June 1st, the business will start under the new system under the NTT Group.

Evolution of devices by photoelectric fusion technology “NEL and FATEC are reliable engineers, and we have provided timely products and services that are ahead of the times by leveraging our unique core technology. NEL’s logical design and manufacturing technology, FATEC To establish photoelectric fusion manufacturing technology by integrating the mounting design and prototype technology of NTT Electronics (Mr. Sawada of NTT) NTT Electronics Cross Technology integrates LSI for digital coherent optical communication and COSA (Coherent Optical Sub Assembly) by silicon photonics technology. We will start providing compact, power-saving, high-performance optical communication devices using photoelectric fusion technology by the end of FY2022. In addition, for the Beyond 5G era, both companies will consider ultra-high-speed, compact, low-cost photoelectric fusion devices and architectures for mounting in base stations, and will provide them widely globally, including Fujitsu base stations. In 2024, an optical / electronic co-package will be installed as an input / output device for communication / computer LSIs. It is said that it will realize optical signal processing. In “Innovation of Communication Technology”, we aim to realize various services by “Network Platform” that applies photoelectric fusion technology. Mr. Tokita of Fujitsu says, “We aim to create value unique to us in an open environment by combining NTT’s Marume vendor network operation know-how and Fujitsu’s communication network equipment development and manufacturing strengths.” On network platforms, many vendors and various service providers offer a variety of services. He also said that he would work on virtualization and openness of network functions and application of photoelectric fusion technology. By doing so, it is possible to move away from the vertically integrated model that depends on a specific vendor in the telecommunications equipment market, and to promote the openness of white boxes and general-purpose software that can be handled by multiple vendors.

Image of application of photoelectric fusion technology to base stations To that end, first, we will apply photoelectric fusion technology to wireless base stations. The company will also work on measures to improve performance, which is an issue in expanding the introduction of virtualized wireless base stations (vRAN), and development of control technology that optimizes wireless access networks. “We will develop an architecture for mounting ultra-high-speed, compact, power-saving photoelectric fusion devices for 5G wireless base stations, but this is an important initiative that can be said to be decisive for the 6G era. For smartphones and tablets. In order to deliver 5G radio waves, it is necessary to install 280,000 wireless base stations in Japan alone, which consumes a huge amount of power. Minimize the power consumption for operating advanced service infrastructure at high speed and in real time. It will be an issue for society as a whole. We would like to succeed in this technological transformation and provide it widely to base stations other than Fujitsu globally. ”(Mr. Tokita of Fujitsu)“ Innovation in computing ”has low power consumption. Work on joint research and development toward the realization of a “disaggregated computing” platform for high-performance computing. “A further expansion of the open network platform. Combining NTT’s photoelectric fusion technology and Fujitsu’s world’s best computing technology used in” Tomitake “, etc., low power consumption for the future that requires enormous data processing We will take on the challenge of developing high-performance, flexible and expandable computing platform technology “(Mr. Tokita of Fujitsu).

Overview of disaggregated computing Disaggregated computing is a new technology that connects the devices that make up computing equipment, CPUs, GPUs, memory, storage, etc. via optical communication, and dynamically uses various resources according to the purpose. It is said that it aims for a new architecture. Mr. Tokita said, “We will realize the world of disaggregated computing, spread it to a wide range of applications, and promote the realization of low-energy and highly efficient ICT systems.” We will drastically review the conventional computing architecture, develop high-performance computing technology with low power consumption, and implement it in all ICT resources. ” After that, he explained that it would be commercialized. NTT has a capital and business alliance with NEC in the summer of 2020 in anticipation of the 6G era, but Mr. Sawada said, “We will drop into fields such as space, submarine cables, and security through comprehensive collaboration with NEC. The purpose of the collaboration with NTT is clear, such as changing computing, changing communication equipment, and making semiconductors together, and then expanding to comprehensive collaboration. ” The scope of the collaboration between the three companies, NEC and Fujitsu, was discussed in the future, but was “a possible story if possible.” Regarding this collaboration with Fujitsu, he said, “It is important not to aim at partnering with a communication machine manufacturer, but to collaborate with a company that has technological and innovation capabilities.”
