This paper proposes an active free space optics (FSO) telecommunication system that enables a mobile terminal to be tracked in user networks of short-range coverage. The central idea is to incorporate a mechanism that controls the transmittal beam direction. This provides the system with a high-speed and ubiquitous optical communication capability over a conventional wireless network with a lower bit rate for control signal transmission. The system configuration including an axis alignment control method is presented. In addition, a prototype of the proposed system is constructed to verify its performance in simulations and fundamental experiments.
