Abstract
The paper presents experimental verification of coexistence and entry into a free space optical link channel. A numerical model, which describes the properties of the LOS (Line of Sight) channel and NLOS (Non-Line of Sight) channel, was formulated and experimentally verified. Experimental work includes an outdoor fog experiment which confirms theoretical predictions. It has been shown that under certain optimal conditions (sufficient transmitting power, dense fog, optimal eavesdropper's receiver distance and optimal angle between the eavesdropper's receiver and the axis of the wireless optical link) unauthorized reception is possible.
