Background:
The demand for accurate and granular Wi-Fi sensing technologies is growing, driven by applications in smart homes, security, and health monitoring. While inherent Wi-Fi capabilities offer a promising platform for environment sensing without specialized equipment, traditional methods like Channel State Information (CSI) sensing face significant limitations. These limitations include the need for sophisticated hardware with MIMO capabilities and device-specific firmware changes to extract necessary data. Additionally, adapting to new environments and subjects often requires extensive data collection and retraining, posing scalability and adaptability challenges.
Description:
Northeastern researchers have created BeamSense, a novel Wi-Fi sensing technology that leverages multi-user multi-input multi-output (MU-MIMO) beamforming feedback information (BFI) to offer detailed characterization of the propagation channel. Unlike traditional methods, BeamSense captures multiple channels between an access point and connected stations, providing high sensing granularity using off-the-shelf devices without requiring MIMO capabilities or firmware alterations. The technology incorporates a Few-Shot Learning (FSL) classification algorithm, enabling it to adapt quickly to new environments and subjects with minimal data. This innovation addresses the limitations of traditional Wi-Fi sensing methods by enhancing granularity, flexibility, and accessibility, and it has demonstrated its potential in providing versatile and scalable sensing solutions.
