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…

This modeling study estimated SAR in a multi-layer head model from a wearable IoT device’s Wi‑Fi/Bluetooth antenna. SAR was reported to be up to 10× higher when the antenna was placed in a headband versus on a helmet. The authors suggest that devices emitting below 3 mW EIRP may be considered environmentally…
