intel-ax200

Description

Intel AX200 (Wi-Fi 6) and the related AX210 (Wi-Fi 6E) are the M.2 NICs that bring 802.11ax CSI extraction into reach via picoscenes / feitcsi. They support 160 MHz channels and 1024-QAM, which means up to 1024 OFDM subcarriers per CSI capture — roughly 4× the resolution of intel-5300 CSI. AX210 additionally operates in the 6 GHz band (Wi-Fi 6E). For 2024+ thesis-relevant Wi-Fi 6 sensing experiments, this is currently the most accessible NIC family.

Specs / capabilities

• AX200: Wi-Fi 6, 2.4 / 5 GHz, 2x2 MIMO, 160 MHz channels, up to 2.4 Gbps PHY
• AX210: Wi-Fi 6E, 2.4 / 5 / 6 GHz, 2x2 MIMO, 160 MHz channels, up to 2.4 Gbps PHY
• Bluetooth 5.2 / 5.3 onboard
• M.2 2230 form factor; CNVio2 / PCIe interfaces depending on host
• CSI exposed via PicoScenes patched firmware

Tooling

• picoscenes platform — primary CSI extraction toolchain
• Linux iwlwifi driver (stock — no CSI without PicoScenes patches)
