Availability modeling of terrestrial hybrid FSO/RF based on weather statistics from tropical region
Free-space optical (FSO) communication links are point-to-point wireless technologies. It provides high data rates up to gigabit per second. FSO link availability is easily affected by different weather conditions. Radio-frequency (RF) can be a complimentary link to the FSO link to increase the a...

| description | Free-space optical (FSO) communication links are point-to-point wireless
technologies. It provides high data rates up to gigabit per second. FSO link availability is easily
affected by different weather conditions. Radio-frequency (RF) can be a complimentary link to
the FSO link to increase the availability. Hybrid FSO/RF is a feasible technology for providing
high availability of point-to-point wireless links. In tropical regions, normally RF link is relatively
sensitive to rain. Availability prediction of hybrid FSO/RF with the selection of suitable RF is
indispensable, especially in tropical regions. In this paper, empirical models are proposed to
predict the link availability of RF, and hybrid FSO/RF over link ranges up to 5 km. The availability
prediction models are based on long-term statistics of atmospheric attenuations from the
tropical climate zone. The RF link availability prediction model is developed for frequency ranges
from 10 GHz to 100 GHz using the ITU-R rain attenuation model. It is link distance, fade margin,
and radio frequency dependent. The proposed availability models can predict carrier as well as
enterprise class availability. The availabilities predicted by proposed models are found in good
agreement with those estimated by ITU-R. |
