We are contributing to implementation of the IOWN, an innovative information processing platform that will reform conventional information and communication systems, break through the limitations of conventional technologies and the barrier of power consumption, and support future societies. Specifically, we are developing technology for maximizing network potential by converting all information transmission and relaying functions into photonics-based ones. We are also working on a self-evolving, zero-touch operation that can promptly provide services in response to user needs; technology for optimizing wireless access; integration of mobile and fixed networks; future network architecture linked with application services; technology that will reduce human impact on the global environment to close to zero; and technology that will make the impacts of changes in that environment tolerable to society.
