Description
Summary:The COVID-19 pandemic further highlighted the need to use low-cost remote monitoring procedures for medical patients. Since the results reported in the literature have shown that the use of Channel State Information (CSI) from Wi-Fi networks to remotely monitor patients can provide means to obtain a powerful medical information package in a non-invasive way and at low cost, a consistent review and analysis of the state of the art on this applied technique is developed in the present work. Initially, a mathematical overview of the CSI technology and its functional model is done. Subsequently, details about the technical approach necessary to use CSI in medical applications and a summary of the studies reported in the literature with such applications are presented. Based on the analyses and discussions carried out throughout this work, a better understanding of the current state of the art is achieved. Challenges and perspectives for future research are also highlighted. •Presents how WiFi Channel State Information (CSI) is used for monitoring vital signs.•One advantage of CSI is low-cost and non-invasive monitoring for patients.•We discuss the operation, tools, and algorithms for CSI extraction and processing.•We classify the studies in the literature that use CSI with a focus on healthcare.•Challenges and future perspectives about the use of CSI for healthcare are presented.
