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.
