Abstract During the NTT R&D Forum 2012, a panel discussion entitled "How Innovation Drives Japan's Development and Growth" was held on February 17. Noritaka Uji, NTT Senior Executive Vice President, participated as a panelist. This article reports on the discussion between the coordinator and panelists.
Abstract We are developing a 120-GHz-band 10-Gbit/s wireless link and have already demonstrated wireless transmission of a 10GbE (10 Gigabit Ethernet) data stream over a distance of 5.8 km. In its present state, the link uses amplitude shift keying (ASK) for the modulation scheme. To improve the system's performance, such as sensitivity and spectral efficiency, we need phase shift keying (PSK) modulation in the 120-GHz band. However, it is difficult to make a PSK modulator for frequencies above 100 GHz because the design is fundamentally more complicated than that for ASK. In this article, we introduce new PSK monolithic microwave integrated circuit technologies for 120-GHz-band 10-Gbit/s wireless links.
Abstract NTT Service Integration Laboratories has developed a security device management platform that includes functionality for issuing smart cards, adding applications to cards after they have been issued, issuing temporary cards when an smart card is lost, and linking with external systems. The platform can support the management of smart cards and other tamper-resistant security devices in a wide range of operational scenarios.
Abstract To overcome the limitations of the current Internet, research and development of future network technologies has been undertaken extensively in the USA, EU, and Asian countries including Japan. This article gives an overview of and describes the current status of Future Networks standardization in ITU-T SG13 (International Telecommunication Union, Telecommunication Standardization Sector, Study Group 13).
