Companies join forces to advance 5G global network slicing services and solutions

Samsung Electronics and KDDI today announced the companies have signed a Memorandum of Understanding (MOU) to form a 5G Global Network Slicing Alliance. Through this new alliance, the companies will work together to introduce an array of commercial 5G network slicing services and assess new business models based on this innovative technology.

This announcement follows the companies’ ongoing efforts in the advancement of network slicing, a market that is expected to grow at over fifty percent annually from 2023 to 2030.1 KDDI and Samsung conducted a field trial in January 2023, which successfully completed Service Level Agreements (SLA) assurance network slicing on a live 5G standalone (SA) network in Tokyo, Japan. The companies also demonstrated network slicing with a RAN Intelligent Controller (RIC) for the first time in the industry back in 2020.


“KDDI has been at the forefront of network slicing innovation, and we are excited to take another significant step forward with Samsung to show how this technology can augment 5G experiences for consumers and businesses,” said Toshikazu Yokai, Chief Network Officer, Managing Executive Officer, Deputy General Manager of Technology Sector at KDDI. “Through the strategic alliance, we not only aim to create new and immersive use cases, but also explore the infinite potential in transforming industries.”


Network slicing enables multiple virtual networks to be created within a single physical network infrastructure, where each slice is dedicated for a specific application or service—serving different purposes. For instance, operators can create a low latency slice for automated vehicles, an IoT slice for smart factories and a high bandwidth slice for live video streaming—all within the same network. This means that a single network can support a broad mix of use cases simultaneously, accelerating the delivery of new services and meeting the tailored demands of various enterprises and consumers.


“Combining Samsung’s strong technical expertise and KDDI’s business acumen, this new alliance will help us facilitate innovation with a shared commitment to keep advancing 5G to the next level,” said Junehee Lee, Executive Vice President, Head of Global Sales & Marketing, Networks Business at Samsung Electronics. “We look forward to expanding our collaboration with KDDI to fully tap into the numerous opportunities that 5G network slicing offers.”


Samsung has pioneered the successful delivery of 5G end-to-end solutions, including chipsets, radios and cores. Through ongoing research and development, Samsung drives the industry to advance 5G networks with its market-leading product portfolio, from vRAN 3.0, Open RAN and Core to private network solutions and AI-powered automation tools. The company currently provides network solutions to mobile operators that deliver connectivity to hundreds of millions of users worldwide.
