Fujitsu announced that it has begun delivery of 5G base station products, comprising of Central Unit (CU) and Radio Unit (RU), to NTT DOCOMO.

The 5G CU products that Fujitsu has started delivering realize the 5G system through a proprietary software design from the company using software-defined radio (SDR) technology, which can implement different wireless technologies on the same hardware. This makes it possible to deploy 5G network quickly and at low cost, using existing 3G, LTE, and LTE-Advanced base station equipment with a minimum hardware changes.

In addition, the 5G RU products have built-in antennas (which had conventionally been installed externally) equipped with beam forming, enabling efficient network deployments. These RU products have a lineup consisting of 3 types of equipment that support 5G frequencies (the 3.7 GHz band, the 4.5 GHz band, and the 28 GHz band). Moreover, regarding the fronthaul interface, these products are compliant with global standard specifications (O-RAN fronthaul interface specifications) set by the O-RAN Alliance.

Supporting the above open interface, Fujitsu's products can connect to various vendors CU/RU products. Furthermore, these products also support the specifications set out in 3GPP's Release 15. This will enable 5G operators to smoothly begin the commercial 5G service.

Fujitsu has been working with NTT DOCOMO to develop a CU and RUs that comply with the O-RAN fronthaul interface specifications. The company aims to strengthen its partnership with NTT DOCOMO, supporting the launch and expansion of the commercial 5G service. 

Hiroshi Nakamura, EVP and Member of the Board of Directors, NTT DOCOMO
NTT DOCOMO is leading the O-RAN Alliance and contributing to the creation of specifications for open RAN. By utilizing 5G base station products compliant with open interfaces, we will build a flexible and efficient 5G network that can handle a variety of use cases, including the B2B2X business in the 5G era.
