| Abstract |
This paper proposes the link performance analysis of the terrestrial free-space optic (FSO) model, intended for deployment in Bhubaneswar smart city. The challenges of atmospheric adversity and its impact on the performance of FSO model have been analyzed from the real-time measured visibility data. A comparative study of different statistical models addressing the relation between measured visibility data and atmospheric attenuation has been carried out. The atmospheric losses such as haze, scintillation, rain, fog are considered for the link analysis due to the tropical savanna climate of the Bhubaneswar city. Thereafter the link margin is calculated for summer, rainy, winter season for the feasible establishment of FSO link. Comparison between two low absorption optical wavelengths such as 850 nm and 1550 nm has been considered for performance analysis. This is because of the commercial availability of optical components. Performance metrics such as received signal power, bit error rate (BER), signal to noise ratio (SNR), link margin has been used for the link performance analysis for a best fit FSO model for deployment in the city. Finally, the maximum achievable data rate is calculated for FSO link in all the three seasons for ensuring high-quality network reach. |
