Experimental Study of Fog Effect on Wireless Optical Communication Channel for Visible Wavelengths

Over the last two decades lot of research is going on in context of selection of right wavelength light source from visible or near infrared region of the spectrum for optical wireless communication under different channel state. In our work, the light sources of wavelength 450nm, 532nm and 635nm from visible spectrum are chosen and investigated. The effect of fog on them using experimental setup in terms of visibility range and attenuation coefficient are analyzed. Obtained results show that 532nm provides the less attenuation coefficient value and more visibility as compared to other two wavelengths. The calculated values are validated with Ijaz fog model
