Abstract


This work seeks to statistically analyze the effect of wavelength transmission in free space over Ilorin, Kwara State, Nigeria using existing atmospheric data for wind velocity from Nigeria Meteorological Agency (NiMET). Scintillation attenuation was calculated based on Rytov approximation for wavelengths of 780nm, 850nm, 1250nm and 1550nm.The signal to noise ratio (SNR) for all the wavelengths considered were also analyzed and it was found that wavelength 1550nm is less attenuated and also has a good SNR as compared with the others. Therefore to improve the efficiency of transmission of FSO, the wavelength of 1550 nm must be used.
