Study of the exposure of 1 year-old infant to 3G femtocell using Polynomial Chaos theory

Wireless communication systems are spreadly used, even though the concern about the exposure to Radio- Frequency electromagnetic fields (RF-EMF). Also children are increasingly exposed to RF-EMF generated by novel devices. Therefore, an assessment of children's exposure to these sources in real scenarios is needed. In this study an analysis of a 1-year-old child exposure to a 3G femtocell emitting in downlink mode has been carried out. In order to estimate the variability of the exposure due to the position of this device with respect to the baby, stochastic dosimetry, based on the Polynomial Chaos (PC) theory, has been used to build surrogate models of the SAR induced in the child at a low computational cost.
