Integrating Sensing and Communications for Ubiquitous IoT: Applications, Trends, and Challenges

Recent advances in wireless communication and solid-state circuits together with the enormous demands of sensing ability have given rise to a new enabling technology, integrated (radar) (ISAC). ISAC captures two main advantages over dedicated functionalities: integration gain efficiently utilize congested wireless/hardware resources, even more interesting, coordination balance dual-functional performance or/and perform mutual assistance. Triggered by ISAC, we are also witnessing paradigm shift ubiquitous IoT architecture, which layers tending partially converge into layer, namely, signaling layer. In this article, first attempt introduce definition analyze various influencing forces, present several novel use cases. Then complement understanding layer presenting key benefits era. We classify existing dominant solutions based on is applied. Finally, challenges opportunities identified. hope that overview article will serve as primary starting point for researchers offer bird's-eye view ISAC-related advances.
