Non-directed indoor optical wireless network with a grid of direct fiber coupled ceiling transceivers for wireless epon connectivity

In this paper we propose an optical wireless system for indoor communication with a grid of ceiling transceivers, based on direct fiber coupling technology. The proposed network is fully compatible with EPON standard that uses point to multipoint broadcasting in the downstream and can guarantee a high speed two-way connection for multiple mobile devices. We present the transmission analysis for the both downlink and uplink and discuss the eye safety issues regarding our proposal. Furthermore, deeper analysis of the system synchronization is conducted and the distribution of the delay in the overlapping zones is presented.
