Abstract
Free-space optics (FSO) offers a lot of network-specific merits over radio-frequency (RF) links because of its license-free bandwidth, ease of installation, and cost for short-distance communication. This investigation offers a framework on the performance of hybrid FSO/RF, which suffers from various atmospheric conditions. To overcome the drawbacks faced by the FSO link, a reliable RF link is used as a secondary link. As observed by comprehensive literature survey, using some technologies like employing relay nodes, the error rate or coverage area can be improved. Further, modulation techniques like binary phase shift key (BPSK) and multiple pulse position modulation (M-PPM) can be used as signaling techniques for improving the performance of communication link. These approaches provide better results in terms of quality of service (QoS), bit error rate (BER), eye opening, jitter, etc., in different weather conditions.
