Korean tech giant will supply 5G radios to underpin NTT

Samsung Electronics announced on Nov. 30 that the company would supply 5G radios to support NTT DOCOMO’s Open Radio Access Network (Open RAN) expansion.

Samsung is scheduled to provide a range of Open RAN-compliant 5G radios covering all of the Time Division Duplex (TDD) spectrum bands held by the operator.

Samsung expected that this expanded portfolio from it would enable NTT DOCOMO to leverage a broad range of spectrum across Japan to build a versatile 5G network.

The two 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,” NTT DOCOMO Vice President Masafumi Masuda said in a statement.

“Solidifying our global leadership, we will continue to build momentum around our Open RAN innovation and provide highly scalable and flexible networks to respond quickly to the evolving demands of our customers.”

Samsung Vice President Satoshi Iwao in Japan said that the bilateral collaboration would be a win-win solution.

“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,” he said.

“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.”

Samsung has pioneered the successful delivery of 5G end-to-end solutions, including chipsets, radios, and cores.
