With proper system design, infrared multi-spot diffusing (MSD) communication links promise an order of magnitude higher bit rates compared to existing radio links. Because of the uniform distribution of the secondary sources (diffusing spots) the channel characteristics and system performance practically do not depend on the particular receiver position with respect to transmitter. However, the amount of received optical signal and noise power depends strongly on the receiver position and orientation with respect to the diffusing spots grid and the ambient light sources. The only way to properly describe such a link is to use a statistical approach. Using this approach, the impact of the optical subsystems on the channel characteristics is investigated and the results prove undoubtedly the great potential of MSD configuration.
