Faced with the urgent need for deep integration of physical digital space and multi-dimensional resource collaborative scheduling in 6G smart factories, the integrated network of sensing and computing, as the core architecture of the next generation mobile communication system, needs to achieve efficient collaboration of sensing, communication, and computing functions in complex dynamic environments. However, existing wireless sensing technologies face bottlenecks such as strong environmental interference, high resource overhead, and difficult multitasking scheduling, making it difficult to meet the needs of high-precision positioning, real-time monitoring, and intelligent decision-making in industrial scenarios. This article aims to explore the key technologies of wireless sensing by analyzing the current research status of Integrated Sensing and Communication network (ISAC), and to provide prospects for application scenarios and verification. The key technologies of wireless sensing include channel sensing precise feedback, multi-point collaborative sensing technology, and collaborative sensing resource allocation. I hope to lay a research foundation for the future research and application of integrated sensory networks.
