Abstract
There is described a building automation system comprising a mobile tag, sensor devices, and a sensor hub. The mobile tag transmits a broadcast beacon based on RF technology. The sensor devices are co-located with light fixtures and include antennas for receiving a broadcast beacon. The sensor devices generate signals associated with the broadcast beacon received by the antennas. The sensor hub receives the signals from each sensor device and determines a location of the mobile tag based on the signals.
