Description
Modern smartphones simultaneously use multiple frequencies, including dual connectivity technology in 5th generation (5G) that combines LTE and Sub-6 bands, to provide high-speed and stable telecommunications. While single-frequency electromagnetic exposure has been extensively researched, studies on the simultaneous effects of multiple frequencies on the human body remain insufficient at present. Smartphones are used in various scenarios. Of particular interest are increasingly common use cases where devices are positioned near the abdomen, such as during mobile hotspot usage or while streaming videos. In this study, we developed a computational smartphone model capable of simulating multiple frequency exposures. We also conducted electromagnetic exposure assessments using a computational human model, focusing on scenarios where devices are used near the abdomen for data communication.
