Abstract

An environmental control system, control apparatus, and control method thereof are provided. The control apparatus receives a plurality of sets of sensed signals from a trackable apparatus, wherein each set of sensed signals is sensed from one of a primary base station and a first secondary base station and the last set of sensed signals is sensed from the primary base station. The primary base station, the first secondary base station, and a second secondary base station have a common coverage area. The control apparatus determines that the trackable apparatus has moved at least a predetermined distance in the common coverage area in a direction away from the first secondary base station and toward the second secondary base station. In responses to the determination, the control apparatus transmits instruction signals to turn off the first secondary base station and turn on the second secondary base station.
