Integrated Sensing and Communication in Wi-Fi and Cellular: An Industry and Standards Perspective

Integrated sensing and communication (ISAC) is expected to be a key enabling technology for diversifying the use cases of future telecommunication systems. Recently, there has been an active push in the industry on ISAC, with several strides being made in standardization efforts in both Wi-Fi and cellular communication domains. This paper provides a comprehensive overview of the current efforts towards ISAC in Wi-Fi and cellular communication (5G and 6G), highlighting current research directions and standardization efforts. The paper also discusses the current advances in channel modeling used for evaluating ISAC systems, and the impact of the different transceiver hardware impairments on ISAC. We also discuss the limitations of current progress and summarize key research directions for the future.
