Samsung Selected by NTT East To Build Private 5G Networks in Japan

Companies team up to deliver Local 5G networks that offer more stable, secure connectivity and greater business opportunities for enterprises

Samsung Electronics announced today the company has been selected by NTT East, to jointly expand the private 5G network business in Japan, helping to support the buildout of secure dedicated networks for various enterprises.

Samsung and NTT East will begin providing commercial private 5G network services to enterprise customers starting in the second quarter of this year.
This announcement follows a series of tests completed last year to verify Samsung’s private 5G network solutions on NTT East’s network, demonstrating the capabilities required to build an optimized private 5G network that meets specific enterprise needs.

Leveraging 5G SA

This month, the companies successfully completed a 5G Standalone (SA) technological verification, achieving increased uplink throughput by optimizing uplink and downlink allocation ratio in NTT East Research Facility. This improved uplink performance will be a key enabler for advanced services that require high data transmission — such as live video monitoring, connected drones and automated vehicles.

For the technological verification, Samsung provided its end-to-end 5G solutions — including its outdoor radio units, baseband unit and 5G SA Core — to deliver the highest standards of quality, interoperability and stability. Samsung also used HPE’s software to ensure security in the network.

This verification was conducted using NTT East’s 4.8 – 4.9GHz spectrum, which is a frequency band dedicated for the Local 5G networks initiative in Japan — a government program that enables enterprises to deploy private 5G networks using the country’s assigned frequency band, independent of traditional mobile networks.


“We are excited to advance in accelerating our private 5G network expansion in Japan,” said Riaki Hoshino, Senior Vice President & Executive Officer at NTT East. “In continuing our collaboration with Samsung, we look to deliver the most innovative 5G services and transformative experiences possible for our enterprise customers, tailored to their specific needs.”

“Private 5G networks, powered by Samsung’s comprehensive portfolio of 5G solutions, will create a new wave of opportunities for enterprises, driven by improved productivity and superior connectivity,” said Woojune Kim, Executive Vice President, Head of Global Sales & Marketing, Networks Business at Samsung Electronics. “We’re proud to support NTT East in the expansion of Local 5G, which will impact a range of industries including agriculture, manufacturing and transportation.

NTT East is a leading telecommunications company, providing services in the east area of Japan.
