Abstract:

Visible Light Communication (VLC) has been gaining attention for many applications as a cost-effective and high bandwidth wireless technology. Visible light positioning (VLP) is often combined with VLC to offer multi-functionalities of illumination, communication, and localization. In this paper, we investigate coverage area and `dead-zone' for the localization of an indoor flying receiver (e.g. drones). For accurate positioning, VLP requires a signal from more than two transmitters. However, the signal from the minimum number of transmitters may not always be available especially in the area close to the walls leading to inaccurate positioning (the dead-zone). The simulation for a typical industrial environment shows that the loss of a signal due to a dead-zone is highly dependent on the divergence angle of transmitters and the field of view of the receiver. The maximum height a drone can reach with a field of view of 85° for VLP systems is about 7.8 m for up to four transmitters without encountering any dead-zones.
