Samsung Electronics on Wednesday announced that it is providing a variety of 5G radios to support NTT DOCOMO’s Open Radio Access Network (Open RAN) expansion plans. It’s been over a year since Samsung and NTT Docomo signed a 5G deal. Now Samsung is adding new radios – including 3.7 GHz, 4.5 GHz and 28 GHz – to its existing 3.4 GHz radio support for DoCoMo. The radios support NTT DoCoMo’s open radio access network (O-RAN) expansion and cover all operator-owned time-division duplex (TDD) frequency bands.
As Samsung expands its portfolio, it will benefit NTT DOCOMO to leverage its spectrum portfolio and be able to develop a versatile 5G network and expand the services it offers to consumers and businesses in all of Japan. The companies also tested the interoperability of these new radios with basebands from different vendors in NTT DOCOMO’s commercial network environment.
