Stochastic Dosimetry Assessment of Human RF-EMF Spatial Exposure Variability in 5G-V2X Vehicular Communication Scenario

The present work was focused on assessing the spatial exposure variability for pedestrians road, in close proximity to a car equipped with 5G-V2X antenna, operating at working frequency of 3.5 GHz and 3D beamforming capability. Indeed, Cooperative Intelligent Transportation Systems (C-ITS) will soon utilize 5G New-Radio (NR) wireless communication overcome limitations current V2X (Vehicle-to-Everything) technologies, enhancing road-safety driving efficiency. However, this transition also introduces heterogeneity, uncertainty radio (RF) levels pedestrian other road-users. To evaluate these new scenarios, we adopted an approach which combines stochastic (metamodeling) technique called Polynomial Chaos Kriging deterministic dosimetry (classical computation techniques). By utilizing approach, were able assess levels, expressed terms specific absorption rate (SAR), 1000 different patterns low computational cost. results showed values compared ICNIRP guidelines highlighted high vehicular scenarios.
