抜粋
This paper discusses the reduction of power consumption in handheld terminals from the viewpoint of system configuration and hardware. The first part discusses system development of portable and personal communication devices, as well as performance trends relating to size, transmitter power, and standby time. We then focus on the PHS (personal handy phone system) and discuss the system technology that plays a basic role in power consumption reduction, together with its effects. The configuration of the handheld terminal from the viewpoint of the hardware as well as the configuration techniques suited to the power consumption reduction are compared and evaluated. The effectiveness is discussed. The future trends in terminal technology are also discussed and a possible direction for research and development is indicated.
