NEC Nets Eye, Local 5G-Developing base station software-ZDNET JAPAN

　NEC Netzu Sai announced on February 28 that it will develop a full -scale business of a self -employed fifth generation mobile communication system (local 5G).The "regional network" and "invil network" were positioned in the focus area of the local 5G, and the idea was to work on responding to next -generation communications such as "BEYOND5G" (5G -year -old communication system).Aiming for sales of 10 billion yen in the local 5G business in 2023.

　Mr. Takayuki Nakagawa, an executive officer at the meeting, said, "Local 5G has been working as an important network since 2019. We believe that local 5G will be the main focus in the future multipath (multipurpose) area network business, focusing on local 5G.I want to play a role as a market leader in a private network. "

　In addition, the spread of local 5G is easy, the cost is low, and the point is that it is always evolving, saying, "We provide digital transformation (DX) in the regional network and invil network area we are good at.It solves management issues and various local communities. "

　NEC Netzu Sai is one of the NEC groups established in 1953 as a communication system construction company.In the fiscal year ending March 2021, sales were 339.1 billion yen, and the number of employees was 7537."Symphonic" has been developed as a business brand that realizes value creation and problem solving by digitalization, and "town development DX" and "work style DX" are set in the focusing business area.

　Local 5G has already been conducted on demonstration experiments, in Hiroshima Prefecture, oyster aquaculture growth and management, remote medicine and river monitoring in Tokushima prefecture, improved productivity of mountainous areas work in Toyama Prefecture, and for climbers in Yamanashi Prefecture.Tourist information systems and Tokyo are used in new work style creation.It is said that Mitsui Fudosan, major manufacturing, and cable TV operators use local 5G to solve social issues and management issues.

　Mr. Nakagawa said, "The know -how of the technical demonstration experiments we have been working on is fully supported by the company that can introduce a service that can introduce the company, including a license application, etc., to fully support the local 5G.I will provide it. "

　The local network, which is located in the focus area in the local 5G business, uses the integrated base station device of NEC Magnus Communications with the efforts of "town development DX".Due to the feature that can cover a wide area with one unit, it will be realized as a model that shares a common core network in the region, so that local 5G can be easily introduced.First, it is said that the business will be expanded in cooperation with cable TV operators."Assuming that it will be used for high -speed Internet services for apartment houses and infrastructure monitoring services such as rivers and roads using 4K images for cable TV operators with optical cables" (Digital Town Promotion Headquarters Yohei Arikawa.).

　Another "Invil Network" has a proposal to build a local 5G environment at the same cost as Wi-Fi using the company's HFR as an initiative of "working style DX".conduct.Here, using the antenna distributed technology (DAS = Distributed Antenna System), it is possible to efficiently build a local 5G environment even in indoor facilities that are partitioned by walls and floors, such as office buildings and hospitals.It is said that a smart building will be realized in combination with various DX services such as work style reform.

　HFR will launch a high-output separation base PRU in June, and will release AAU and ORAN-MUX, an indoor separate base station, in August.NEC Nets Eyei has various smart building solutions with various smart building solutions, including developers services such as building equipment integration management and service operation management, management companies such as maintenance work management, and tenant services such as work style reform services.We will proceed with package proposals that combine 5G.

　In addition, as a response to BEYOND5G, the FW-L5G-1, a software base station jointly developed with FLARE SYSTEMS, a startup company from the University of Tokyo, will be used.This provides all functions such as the core, control unit, distributed unit, and wireless unit related to local 5G in software, providing base station functions with general -purpose servers.The design is flexible, and it is used to promote the demonstration for Beyond5G.The FW-L5G-1 has been developed with Flare Systems based on the Creation Program for Created the University of Tokyo University of the University of Tokyo.

　It is said that using a general -purpose server can reduce costs than base stations using special equipment, and can operate for a long time using commercially available portable power supply even in places where there is no power supply.In addition, it is said that it has excellent customizability, such as responding quickly to "semi -synchronous TDD" and being able to freely change communication capacity from users and communication to users according to the application.Mr. Arikawa said, "We will work on the cutting -edge area in anticipation of the locals of 5G with the planning skills and development skills of the next -generation network of Flare Systems and the ability to build the NEC Netzui system system.。
