ABSTRACT=Recent advancements in Radio Frequency (RF) sensing technology can be attributed to the development of Internet of Things (IoT), healthcare, RF-Identification, and communication applications. RF-sensing is a multidisciplinary research field that requires expertise in computing, electronics, and electromagnetics to cover all system features, including protocol development, antenna design, sensor integration, algorithms formulation, interconnection, data, and analytics. The overarching aim of this work is to present detailed information about RF technologies and their innovations and application diversity from the novel work carried out at CSI Lab, together in one platform with an extensive survey. This paper presents state of the art application and RF sensing that include W-Fi, radar, SDR and RFID based sensing. A comprehensive survey and study of the advantages and limitations of each non-contact technology is discussed. Additionally, open research gaps have been identified as well. Decades of knowledge and experience have been put to use in order to meet new challenges and demands. The development and study of RF systems, IoT, and RFID sensing, as well as research and deployment activities, are briefly discussed. The emerging research projects with industry, institutional research centers, and with academic studies are also addressed. Finally, an outline of identified potential future research areas provided, emphasizing on opportunities and challenges.
