Commenting on the development Sadayuki Abeta, OREX Evangelist, Global Business Department, NTT DOCOMO, said: ‘Open RAN is essential for onward development of mobile networks. Especially, vRAN is key in realising flexible network evolution. At this time, development of high performance vRAN with Fujitsu base station software and NVIDIA GPU as hardware accelerator has been completed. It will contribute to further development of DOCOMO’s network, and will promote more efficient global deployment of Open RAN by accumulating commercial know-how.’
