Wi-Fi Sensing Based on IEEE 802.11bf

Summary: The vision of 6G involves creating authentic digital twin representations of the physical world, requiring new sensing solutions and utilizing the mobile communication network as a sensor. The evolution of cellular systems to mmWave bands in 5G and potentially sub-THz bands in 6G will lead to small cell deployments dominating and providing opportunities for mobile network sensing. The paper focuses on designing a cellular joint communication and sensing (JCAS) system, discussing waveform choice, integration of sensing capability, and future advanced JCAS systems with distributed massive MIMO.
