Portable Mobile Terminals and Information Appliances

  • The Ceramic Society of Japan


Mobile communication service began in December 1979, in Japan, ahead of the United States and European countries. The automobile telephone service provided by the Nippon Telegraph and Telephone Public Corporation (currently NTT), targeting the 23 wards of Tokyo, was the first service of its kind. The mobile communication service originally adopted was the FDMA system (Note 6.1), an analog system that utilizes the 800 MHz range, but was transformed later to adopt the TDMA system (Note 6.2), a second-generation digital system that can effectively utilize higher frequencies, responding to an increase in the number of subscribers. Today, the TDMA system is giving way to the CDMA system (Note 6.3), a third-generation system that uses higher frequency effectively and enables high speed data transmission.
