Enabling multi-person differentiation is crucial for the wide adoption of Wi-Fi sensing, so it is imperative for WiFi sensing to gain GHz-level bandwidth and thus to achieve sufficient spatial resolution. Whereas stitching wide bandwidth leveraging continuous channel samples appears to be plausible,...
