Smart buildings are physical environments — including offices, commercial spaces, and residential dwellings — that integrate networked sensing and IoT infrastructure to enable automated monitoring and management of occupancy, energy use, and environmental conditions. In the context of WiFi/CSI sensing research, they serve as the primary deployment setting for device-free systems that leverage existing wireless infrastructure to detect presence, count occupants, and estimate room-level activity without requiring residents to carry dedicated devices. Key variants include commercial smart buildings with dense, multi-zone office layouts and residential smart environments such as multi-room apartments, each presenting distinct challenges in terms of interference, spatial complexity, and the scale of occupancy to be detected.
