Description
The rapid proliferation of mobile devices has heightened public concerns regarding human exposure to radio-frequency radiation, particularly from uplink transmissions. This study focuses on characterizing UL exposure specifically during voice call applications, comparing different configurations, providing a comparison between native mobile voice calls and voice over Internet protocol (VoIP) calls via WhatsApp. The research is based on the measurement data of the EXPLORA and SEAWAVE projects in Paris, which also provides an insight into the effect of bandlock on the averaged transmitted (TX) power. By investigating the difference in TX power, our findings reveal significant variations in uplink exposure levels of mobile phone voice calls. These results provide valuable insights into the differences between native and VoIP-based voice calls. Furthermore, this study enhances our understanding of real-world exposure dynamics, lays the groundwork for future research aimed at optimizing wireless network configurations to minimize UL exposure while maintaining high-quality voice communication services.
