Simulation of spatial variations of RF exposure within a macrocell

The spatial variations of the time-averaged total whole-body SAR due to voice calls within a 3G macrocell are investigated by simulations. The impact of cell size, usage intensity, usage environment and user morphology is investigated. It is shown that within a cell, total SAR values are minimal when uplink exposure equals downlink exposure. Average exposure increases when the cell size increases, when calls are longer and executed indoor, and when executed by children.
