Original Abstract:
Simultaneous wireless information and power transfer (SWIPT) has long beenproposed as a key solution for charging and communicating with low-cost andlow-power devices. However, the employment of radio frequency (RF) signals forinformation/power transfer needs to comply with international health and safetyregulations. In this paper, we provide a complete framework for the design andanalysis of far-field SWIPT under safety constraints. In particular, we dealwith two RF exposure regulations, namely, the specific absorption rate (SAR)and the maximum permissible exposure (MPE). The state-of-the-art regarding SARand MPE is outlined together with a description as to how these can be modeledin the context of communication networks. We propose a deep learning approachfor the design of robust beamforming subject to specific information, energyharvesting and SAR constraints. Furthermore, we present a thorough analyticalstudy for the performance of large-scale SWIPT systems, in terms of informationand energy coverage under MPE constraints. This work provides insights withregards to the optimal SWIPT design as well as the potentials from the properdevelopment of SWIPT systems under health and safety restrictions.
Context On This Paper:
The main objective of this paper is to provide a framework for the design and analysis of far-field simultaneous wireless information and power transfer (SWIPT) under safety constraints. The research question is how to comply with international health and safety regulations while using radio frequency (RF) signals for information/power transfer. The methodology includes outlining the state-of-the-art regarding specific absorption rate (SAR) and maximum permissible exposure (MPE) regulations, proposing a deep learning approach for robust beamforming subject to specific constraints, and presenting an analytical study for the performance of large-scale SWIPT systems under MPE constraints. The results show insights into the optimal SWIPT design and the potentials from the proper development of SWIPT systems under health and safety restrictions. The conclusion is that SWIPT can be a key solution for charging and communicating with low-cost and low-power devices, but compliance with health and safety regulations is crucial.

Flycer’s Commentary:
The paper discusses the challenges of implementing simultaneous wireless information and power transfer (SWIPT) while complying with international health and safety regulations. The authors provide a framework for designing and analyzing SWIPT systems under safety constraints, specifically focusing on two RF exposure regulations: specific absorption rate (SAR) and maximum permissible exposure (MPE). They propose a deep learning approach for designing robust beamforming subject to specific information, energy harvesting, and SAR constraints. Additionally, the paper presents an analytical study of large-scale SWIPT systems’ performance in terms of information and energy coverage under MPE constraints. This work provides valuable insights into the optimal SWIPT design and the potential benefits of developing SWIPT systems under health and safety restrictions. For small businesses interested in AI applications, this research highlights the importance of considering safety regulations when implementing SWIPT technology. It also demonstrates the potential of using deep learning approaches to design robust and efficient SWIPT systems.
