Rainfall in tropical environments acts as a dominant parameter for estimating the availability of free-space optics (FSO). Long fades are caused by precipitation in particular heavy rains, and this precipitation increases atmospheric attenuation due to rain and reduces the availability of optical power from FSO links. In this paper, the link availability of an FSO system is estimated under the impact...
Availability is a major concern to measure the QoS of Free Space Optical (FSO) communication link. In tropical areas, rain is the most dominant factor affecting the FSO link availability, whereas haze has no significant impact on FSO link availability compare to rain. In this paper, availability assessment of FSO was examined based on predicted atmospheric attenuations due to rain and haze. The predicted...
Free Space Optics is a promising optical wireless technology in broadband networks. It uses laser as a medium of transmission between two transceivers. In tropical climate, haze is one of the weather phenomenons which reduce the visibility. Low visibility increases atmospheric attenuation and reduce the availability of optical signals for free space optics (FSO) links. In this paper, the effect of...
Attenuation due to rainfall can severely degrade the FSO links operating under tropical weather. It restricts the distance of FSO communication systems and limits the availability for line-of-sight terrestrial link. Practical FSO link has been setup, monitored and analyzed. A commercially available FSO system was installed at 800 m length together with rain fall intensity measurement facility at IIUM...
