Abstract
Abstract
FSO systems have unlimited bandwidth and unlicensed availability, which makes them an attractive low-cost solution. Because the wavelength of the signal is close to the diameter of the dust particles, they have an impact on the FSO link by reducing its availability and causing its interruption. To solve this, a hybrid system of two RF/FSO links to avoid transmission interruption is necessary because the effect of dust on the RF links is slight because of their large wavelength compared to the size of the dust particle. In this paper, hybrid RF/FSO links are simulated and investigated under dusty conditions. The BER, Q-factor, and data rate are calculated for 2, 10, and 25 GHz of RF link. Besides, the wavelength of 1550 nm is used for the FSO link. The results produced at 10 and 25 GHz are suitable for wireless communication. So, it is the best link to use as a backup link with the FSO system. The performance of 1550 nm is poorer. The lower frequency of the RF link (2 GHz) has a similar link with the FSO. Under different dust conditions, the transmission rate is enhanced by a 25 GHz link. The link distance is reduced by decreasing the visibility of the weather.
