Abstract
EMF exposure of people induced by both base station antennas and mobile terminal devices, in a heterogeneous network environment, in a given area, is addressed in this paper. The Specific Absorption Rate (SAR) and the Exposure Index (EI) are used to evaluate exposure, which takes multiple systems, users, postures, and usage profiles into account, among other aspects. One analyses the exposure in heterogeneous networks, consisting of GSM, UTMS, LTE and WLAN systems, for multiple usage scenarios. By using full systems simulations and exposure models, one estimates the EI for several conditions. The use of power control has a major impact on the SAR a person is exposed to. It is verified that, for the scenario under analysis, the uplink power of users’ own terminal contributes to more than 90 % to the overall SAR.
