Human RF-EMF Exposure Assessment Due to Access Point in Incoming 5G Indoor Scenario

Two different indoor UPA antennas at 3.7 and at 14 GHz are modelled to simulate the presence of a 5G AP in a room. Two different human models and different configuration scenarios are considered, where the UPA antenna gain is maximized to obtain the RF-EMF exposure assessment. The highest SAR10g levels were obtained in the head area for all the exposure scenarios and the highest SAR10g peak values were measured when the UPA was placed laterally to the human model. We highlight the reciprocal position between the antenna and the model head and the frequency range and the distance are factors that could greatly influence the levels of exposure. The targeted biological applications are the calculated SAR10g distributions in some specific tissues of the two human models, due to the exposure to 5G AP. We have expanded the knowledge on the RF-EMF exposure assessment on a single user, considering novelties introduced by the incoming 5G networks in indoor scenarios.
