The Intel AX200 is a commercial Wi-Fi 6 (802.11ax) network interface card (NIC) that supports Channel State Information (CSI) extraction, making it widely adopted in Wi-Fi sensing research as an accessible and affordable hardware platform. Its significance lies in enabling researchers to collect fine-grained CSI data across multiple subcarriers and antenna streams without requiring specialized or proprietary equipment, thereby lowering the barrier to entry and improving reproducibility across studies. The AX200 is commonly paired with open-source tools such as the Linux CSI Tool or nexmon CSI patch and is often compared against earlier platforms like the Intel 5300 NIC, representing a more modern alternative with broader frequency band support including both 2.4 GHz and 5 GHz operation.
