description |
Nowadays, free space optics (FSO) technology is one of the emerging technologies utilized
as a complementary over radio frequency wireless technology with limited spectrum
bandwidth to meet the high bandwidth demand. FSO technology fulfills the demands for massive
bandwidth, faster data rate and low installation and maintenance cost. However, FSO transmission
links for outdoor networks are vulnerable to atmospheric turbulence specifically in
harsh weather conditions in which it deteriorates the performance of FSO systems. In
this paper, a critical study on the performance of the FSO links in different dust storm
conditions is presented. We aim to analyze the performance factors such as transmitted power
control and link length that contribute to increase in signal-to-noise (SNR) ratio and
bit-error-rate (BER) for On- Off Keying (OOK) modulation scheme. The results indicate
that under low visibility, shorter link length performs better while increase in
transmitted power contributes to small improvements. In contrast, at higher
visibility, power control makes significant difference. A “9dbm” power increase over 1km
link contributes 400m visibility improvement for OOK modulation. However, these
visibility improvements will degrade proportionally as the link length is reduced. |
