Occupancy and Presence
Occupancy Detection
Binary occupancy from WiFi CSI change-point detection on an empty-room baseline — why it tolerates noise, how it differs from MAC counting, and HVAC control semantics.
Presence & Breathing
Micro-Doppler presence sensing from WiFi CSI — respiration band physics, SNR requirements, still-person detection, and why PIR cannot see periodic chest motion.
Occupancy Analytics
Anonymous occupancy analytics from WiFi CSI — temporal aggregation, utilization metrics, zone heatmaps, GDPR-safe sensing vs MAC tracking, and honest headcount limits.
Motion, Safety, and Automation
Motion & Activity
Human activity recognition on WiFi CSI — CSI-speed modeling, dual-stream transformers, spectrogram classifiers, and cross-site transfer.
Elder-Care Monitoring
Ambient elder-care sensing with WiFi CSI — anomaly-based fall detection, inactivity monitoring, online adaptation, and non-medical boundaries.
Security & Intrusion
Zone-level intrusion detection with WiFi CSI — NLOS motion through drywall, darkness-invariant sensing, device-free vs MAC tracking, and what you learn vs what you cannot.
Smart-Home Automation
WiFi presence sensing for home automation — presence-hold vs motion-pulse events, debouncing, hysteresis, and why occupancy beats PIR for HVAC and lighting scenes.
