10-Gbit/s Phase-shift Keying Modulator and Demodulator MMICs for 120-GHz-band Wireless Link
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.

Security Device Management Platform
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.
