Abstract
The history and present status of millimeter-wave communications systems in Japan will be reviewed and device development activities presented. The development of optical communication devices will also be discussed. Systems to be discussed include a 23-km link operating in the 40-80 GHz range through one waveguide with a capacity of 300,000 telephone channels.
