MWC 2019 : Cisco said that it is building world's first end-to-end fully virtualized and cloud native mobile network for 5G deployment for Japanese firm Rakuten Mobile Network (RMN), a wholly owned subsidiary of Rakuten. Rakuten is preparing to debut in Japan as a fourth major mobile carrier in October 2019. To reduce its network investment to just a fraction of conventional levels, the company is heavily investing in software driven new technologies like virtualization and telecom cloud. "Rakuten is taking a cutting-edge approach to mobile networking, modelling a new type of network that is software-powered and automated from top to bottom," said Tareq Amin, chief technology officer, Rakuten Mobile Network.
