The Intel AX210 is a commercial Wi-Fi 6E network interface card (NIC) capable of operating across 2.4 GHz, 5 GHz, and 6 GHz frequency bands, widely used in CSI-based Wi-Fi sensing research to capture fine-grained channel state information from wireless signals. It matters to the field because it represents a modern, accessible, and reproducible hardware platform that enables researchers to collect high-resolution CSI data without requiring specialized or proprietary equipment, thereby lowering barriers to replication and cross-study comparison. The AX210 is often paired with tools such as the Linux 802.11 CSI Tool or similar firmware-level extraction utilities, and its support for wider bandwidths and more subcarriers compared to older NICs like the Intel 5300 makes it a preferred choice for sensing tasks requiring richer spatial and frequency information.
