Toward ISAC-Inspired WiFi–Radar Fusion for Privacy-Preserving Elderly In-Home Monitoring

Abstract

Population aging is increasing demand for unobtrusive in-home monitoring, while cameras raise privacy concerns, and wearables depend on user compliance. This critical survey and design study compares WiFi channel-state information sensing and millimeter-wave FMCW radar for fall detection, activity recognition, and vital-sign monitoring.
