It has been almost four years since the research and development of next-generation mobile communication systems (Beyond 5G/6G) started around 2020. Much basic and fundamental research has been conducted in Japan with the help of contract research and research grants from the Ministry of Internal Affairs and Communications and NICT. Similar funding and R&D are also being conducted in many overseas countries. In the midst of this R&D competition, the World Radio Conference was held in December 2023 to discuss the frequency bands that could be used for Beyond 5G/6G. This included discussions on millimeter waves and terahertz waves. From this point forward, standardization work will be carried out by 3GPP and development will be carried out for implementation around 2030. This presentation will review the state of R&D to date and discuss future directions. In particular, it will discuss millimeter waves and terahertz waves, which have attracted attention as new frequency bands for Beyond 5G/6G, outlining the national discussions to date and what practical applications are currently possible.

KDDI group set forth a vision, “KDDI VISION 2030: The creation of a society in which anyone can make their dreams a reality, by enhancing the power to connect”. We aim to connect and protect lives, connect day-to-day lives, and connect hearts and minds with utilizing 5G communication as the core.

Under this vision, we have launched “Satellite Growth Strategy”, pursuing our business growth strategy in the focus areas centered on 5G. With telecommunications which is the power to connect at the center, we will make new expansions into business areas that are positioned like satellites.

In this session, we would like to share this strategy with you, and introduce our fundamental research initiatives that align with this strategy, as well as our social implementation initiatives carried out in collaboration with our partners.

Japan is currently facing social issues such as a declining birthrate, an aging population, and a labor shortage. In order to solve these social issues, it is essential that a new industrial society in which robots and unmanned industrial equipment play an active role will emerge. To achieve this, it is essential to build a highly reliable and stable next-generation mobile communication infrastructure for industrial use.

Currently, social implementation of industrial mobile communication infrastructure is not progressing due to a lack of engineers who understand 5G wireless communication technology and a lack of economical and easy-to-use network products, as well as PoC and use cases that contribute to industrial innovation.

In this performance, ISL Networks CTO Kubota, who has over 20 years of experience in mobile industry (e.g. mobile carriers and global vendors), will provide current issues in Japanese industry, advisory services to address them, and optimal solutions according to use cases. Introducing ISLN 5G packages and products.

By utilizing these services and solutions, companies can expect to use 5G to solve business issues, reduce on-site costs, and improve productivity.

ISL Networks implements next-generation mobile communication technology into society and builds new social infrastructure.

The "Local 5G" market in Japan is expanding its utilization area, especially in the field of Proof of Concept Experiment (PoC), and 2024 is expected to be the year when local 5G utilization will make a significant progress from the stage of small-scale PoC to concrete utilization with a view to commercialization.

We are working with Taiwanese vendor Quanta Cloud Technology to deploy Sub6 local 5G systems in Japan.

In order to deploy, we provide our service that is called "Subscription 5G". It is a low-cost rental model that uses Core-sharing technology to reduce the initial cost which is always raised as a barrier to local 5G deployment.

In this presentation, we’ll provide information on checkpoints to select the system for local 5G deployment. In addition, we would like to introduce demonstration video to show the “real throughput values" that cannot be confirmed from catalog specifications. It is important when using local 5G in a commercial environment.

Moreover, we’ll demonstrate the way of operational monitoring by displaying the GUI screen of OmniView which is a dedicated tool of operational monitoring. It is essential when it comes to actual operation in real site.
