Energy saving features of the Autoplex cellular telecommunications system

Autoplex is a cellular mobile telecommunications system that uses a distributed power system as part of its total approach to providing high quality, high availability communications. First, the Autoplex system is described briefly. Then, the contribution of its distributed power system to overall system availability is discussed. Finally, the contribution of dynamic power control to energy savings in the Autoplex system is described. A statistical model of the interaction of dynamic power control with mobile telephones and its effect on power drawn from the DC power plant is also presented. It relates the mobile telephone´s physical location to the RF power level transmitted by the cellular system. The RF power, in turn, is related to the DC power drawn from the battery plant. This statistical model is based on the mobile telephone subscriber´s physical position and is the basis for determining the energy savings in the Autoplex system.<>
