Near-fiber-optic-speed 300-GHz-band link and a dedicated CMOS transceiver

The data rate of wireless communication is approaching that of fiber optics. The key technology for speeding up wireless communication is terahertz. We demonstrated ultrahigh-speed wireless communication using a terahertz CMOS transceiver. In this paper, social and technical backgrounds of wireless communication using a 300-GHz band in terahertz are discussed. The potential communication speed in the 300 GHz band is also discussed. Finally, we will introduce our 300-GHz-band CMOS transceiver.
