This engineering/simulation study evaluates tissue SAR from a smartphone operating under single-frequency versus combined (simultaneous 4G and 5G) RF exposure scenarios using multi-pose human models. It reports that peak SAR in various tissues under multi-frequency exposure was 1.02 to 15.85 times higher than under…
