Location Data Analytics in Wireless Lighting Systems

Location data analytics refers to the statistical analysis of data pertaining to user location. Such analytics offers useful insights into the interactions among occupants and with their environment. Based on the insights, building facility management may be improved. We consider location data analytics using wireless sensors, which are part of a wireless lighting system, to collect radio received signal strength indicator data resulting from device transmissions from user mobile devices. Zone positioning of users is first performed. Zone position data are then used for analytics to obtain: 1) occupancy density; 2) environment characterization; 3) crowd detection; and 4) occupant connectivity. The approach is evaluated in a simulated open-plan office lighting environment considering simple occupant motion profiles and wireless device transmission models.
