Description
PicoScenes (Jiang, Li et al. 2021/2022) is a unified Wi-Fi sensing platform that combines CSI extraction, packet injection, and signal processing across heterogeneous NICs (Atheros QCA9300, Intel 5300, Intel AX200/AX210). It supplants per-chip tooling (Halperin's tool, Atheros CSI Tool, Nexmon) with a single MATLAB / Python API and adds 802.11ax (Wi-Fi 6) CSI extraction on Intel AX200/AX210, which closes the gap between commodity Wi-Fi 6 deployments and what CSI researchers can measure. Listed here as Hardware because the platform is silicon-specific and most papers cite the platform alongside the underlying NIC.
