Paper Abstract

For determination of the limitng error rate in mobile indoor optical diffusion networks, which are working in infrared spectral area, is one of crucial parameters the knowledge of the light distribution within the overlaying premises. Because it is general knowledge that the achievement of the secure discriminating level at receiving logic 1 and logic 0 requires to capture the satisfactory quantity energy, that is the bigger by the bigger is the demands on the error rate decreasing and what higher is the data signaling rate. This contribution describes the experimental results of the light distribution inside a model rooom. Measuring configuration consists of diffuse source and receiver. Position of the source is especially the corner of pico-cell. Measurements have been achieved in the empty room, the room with obstacles and for different surface walls. Results are processed graphically in shape putting detailed statement about spatial luminosity distribution with determination of critical zones. The operating LED wavelength is about 700 nm.
