Fujitsu today announced that it has begun delivery of 5G base station products, comprising of Central Unit and Radio Unit to NTT DoCoMo for the commercialization of the fifth generation mobile communications system (5G) in Japan. 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 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.
The Fujitsu 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). These products are compliant with global standard specifications set by the O-RAN Alliance. Supporting the above open interface, Fujitsu’s products can connect to various vendors CU/RU products. 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.
