Japanese provider NTT DoCoMo and compatriot agency NEC introduced that they’ve expanded multi-vendor interoperability by interconnecting a brand new 5G base station baseband unit (5G-CU/DU), developed by NEC and Samsung Electronics and compliant with O-RAN Alliance specs, with 5G base station distant radio items (5G-RUs) of different distributors on DoCoMo’s business community.

NTT DoCoMo and NEC famous that increasing multi-vendor interoperability primarily based on O-RAN open interface specs will allow essentially the most applicable base stations for use relying on deployment situations and making the most of particular vendor and gear traits.

The brand new 5G base station baseband unit from NEC, the companions mentioned, is “interoperable with all current distributors’ 5G base station distant items in DoCoMo’s community owing to its adoption of O-RAN open fronthaul specs.” They mentioned it’s also suitable with all current 4G base stations in DoCoMo’s community due to its adoption of O-RAN open X2 specs.

Multi-vendor interoperability utilizing O-RAN open fronthaul specs was additionally confirmed for NEC’s macro-cell 5G-RU, which offers extensive space protection, and for NEC’s fronthaul multiplexer (5G-FHM), which copies and combines the fronthaul indicators to and from a number of 5G-RUs to type a single space; each are new 5G base station gear choices.

Throughout their collaboration, DoCoMo chosen the check objects, executed the multi-vendor interoperability assessments, and analyzed the outcomes; NEC and Samsung Electronics provided the 5G base station gear and analyzed the check outcomes.

“The widespread adoption of O-RAN-compliant merchandise will allow Docomo to construct extremely versatile networks and supply 5G companies that meet buyer wants,” mentioned Naoki Tani, SVP of NTT DoCoMo. “The conclusion of multi-vendor interoperability with this new gear developed by NEC and Samsung Electronics represents a big step within the enlargement of the O-RAN ecosystem. DoCoMo will proceed to work with trade companions to advertise open RAN and 5G companies.”

“We’re very happy to have cooperated with Samsung Electronics in growing an O-RAN-compliant 5G base station that permits multi-vendor interoperability. NEC will make the most of the O-RAN know-how acquired on this initiative to proceed contributing to DoCoMo’s 5G community and the enlargement of 5G networks worldwide,” Atsuo Kawamura, EVP at NEC and president of the corporate’s Community Providers Enterprise Unit.

Going ahead, NTT DoCoMo, NEC, and Samsung will proceed testing 5G base station gear and communication methods scheduled to be used in DoCoMo’s 5G business community.

NTT DoCoMo ended August with a complete of 240,000 subscribers within the 5G phase after launching business companies in March, the corporate’s President and CEO Kazuhiro Yoshizawa just lately mentioned throughout a convention name with buyers.

On the finish of the fiscal quarter ended June 30, the provider had 150,000 5G clients, the chief mentioned.

Yoshizawa mentioned NTT DoCoMo expects 5G to begin to attain mass market scale within the second half. The corporate is sustaining its goal of two.4 million 5G subscribers on the finish of the monetary yr ending March 30, 2021.

NTT DoCoMo beforehand mentioned it expects to succeed in 10,000 5G websites by June 2021 and 20,000 by March 2022.
