Description
Next-generation wireless infrastructure is expected to provide both connectivity and sensing through a unified ISAC framework, yet the tradeoffs among communication bandwidth, waveform design, and radio architecture remain largely unexplored. While existing mmWave radars deliver high-fidelity sensing, they operate as standalone systems with dedicated hardware and waveforms. FutureG networks, in contrast, must enable sensing and communications to coexist on shared wireless infrastructure.
Recent passive wireless sensing approaches have demonstrated the ability to leverage existing communication links for activity recognition, localization, and environmental awareness using machine learning and AI models. However, these systems often rely on data-driven training, are sensitive to environmental dynamics, hardware variability, and deployment conditions, and provide limited insight into the fundamental relationship between communication resources and sensing performance. A fundamental open question is how sensing performance scales with communication bandwidth and whether communication signals alone can provide reliable sensing without dedicated radar transmissions.
To address these gaps and systematically evaluate the relationship between communication bandwidth and sensing performance, we present an open SDR-based framework for investigating bandwidth-scalable ISAC. Leveraging OpenWiFi as a MIMO Wi-Fi radar platform, the framework performs simultaneous sensing and communications using shared communication waveforms without dedicated radar transmissions. Communication-based sensing performance is benchmarked against an industry-grade TI 60–77 GHz mmWave radar serving as ground truth. The resulting platform enables controlled studies of sensing accuracy, range resolution, Doppler estimation, and communication performance across varying bandwidths, providing a reproducible pathway from today's Wi-Fi-based sensing systems to future Massive-MIMO mmWave ISAC architectures.
