Occupancy detection refers to the task of determining the presence, count, or distribution of people within an indoor space using wireless signal measurements, such as those derived from Bluetooth Low Energy or WiFi channel state information, without relying on dedicated wearable devices or cameras. It matters for the field because accurate occupancy information enables a wide range of applications including smart building energy management, security monitoring, and crowd safety, all while preserving user privacy. Key variants range from binary presence detection (occupied versus unoccupied) to finer-grained estimation tasks such as crowd density quantification and movement or flow tracking across zones.
