In this paper we present a hybrid indoor infrared laser wireless system with tracked 10Gbps downlink and non-directed 1Gbps uplink. We show a novel localization system based on angle reflectors and image sensor that is able to provide exact coordinates of the receiver apertures. We also build simple mathematical model of the downlink and the uplink and show some mathematical results for the bit error...
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...
In this paper we propose a novel indoor optical wireless system for personal area networks based on MEMS mirrors and image sensors. The tracking system allows full user mobility and the directed link configuration guarantees high bit rates and energy efficiency due to the narrow beams. We make a simple simulation to analyze the bit error rate in dependence on the received power and beam spot size.
