Abstract :
Free-space optical (FSO) links are perspective wireless optical communication systems utilizing modulated laser radiation to transmission of information. Because of propagation of the light through an atmosphere in case of a terrestrial link, strong dependence on weather conditions is observed. Several mitigation techniques were investigated, for an instance beam tracking, spatial diversity in multiple-input multiple-output systems and a wavelength diversity technique. In this paper, performance of FSO and radio-frequency (RF) hybrid link working at the wavelength of 850 nm and 5 GHz, respectively, is analyzed in specific urban area.
