Dataset for Learning the Beamforming Feedback for Simultaneous Multi-Subject Sensing

This dataset enables advanced Wi-Fi sensing applications, including multi-subject monitoring for home surveillance, remote healthcare, and entertainment. It focuses on Beamforming Feedback Information (BFI) as a proxy for Channel State Information (CSI), eliminating the need for firmware modifications and enabling single-capture data collection across multiple channels between an access point (AP) and stations (STAs). Collected in three environments, this dataset involves three subjects performing 20 distinct activities, facilitating generalization over unseen environments and individuals.本数据集旨在支持高级Wi-Fi感知应用，包括家庭监控、远程医疗和娱乐领域的多目标监控。该数据集聚焦于将波束成形反馈信息（BFI）作为信道状态信息（CSI）的代理，从而消除了对固件修改的需求，并实现了接入点（AP）与站（STAs）之间跨多个信道的单次捕获数据收集。该数据集在三个不同环境中收集，涉及三个受试者执行20种不同的活动，有助于在未见过的新环境和个体上实现泛化。
