This builds upon the two companies’ 5G agreement previously-announced in March 2021, in which NTT DOCOMO selected Samsung as its 5G network solutions provider. Samsung now adds new radios — including 3.7GHz, 4.5GHz and 28GHz — to its existing 3.4GHz radio support for NTT DOCOMO.

This expanded portfolio from Samsung will enable NTT DOCOMO to leverage its broad range of spectrum across Japan to build a versatile 5G network for diversifying their services offered to consumers and businesses. The companies have also been testing the interoperability of these new radios with basebands from various vendors in NTT DOCOMO’s commercial network environment.

“We have been collaborating with Samsung since the beginning of 5G and through our Open RAN expansion, and we are excited to continue extending our scope of vision together,” said Masafumi Masuda, Vice President and General Manager of the Radio Access Network Development Department at NTT DOCOMO. “Solidifying our global leadership, we will continue to build momentum around our Open RAN innovation and to provide highly scalable and flexible networks to respond quickly to the evolving demands of our customers.”

“Japan is home to one of the world’s most densely populated areas with numerous skyscrapers and complex infrastructure. Samsung’s industry-leading 5G radios portfolio meets the demands of low-footprint, low-weight solutions, while also ensuring reliable service quality,” said Satoshi Iwao, Vice President and Head of Network Division at Samsung Electronics Japan. “As NTT DOCOMO continues to accelerate its Open RAN innovation, we look forward to working together to deliver a richer experience to consumers and generating new business opportunities.”

With today’s announcement, Samsung introduces its new 28GHz Radio Unit (RU) for the first time — as a new addition to its portfolio of leading mmWave solutions. This RU, which weighs less than 4.5kg (~10lbs), features a light and compact form factor with very low power consumption, enabling flexible deployments in various scenarios. Additionally, Samsung’s 3.4GHz, 3.7GHz and 4.5GHz radios are also Open RAN-compliant and designed to deliver high performance and reliability.

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