Free space optics (FSO) is getting increased popularity during last few years due to its increased power efficiency for reasonably longer distances. Moreover, it provides data rates that can cater for our future broadband telecommunication requirements besides resolving the last mile access bottleneck. But FSO links are subjected to various kinds of signal deteriorations and attenuations due to different...
Line of sight optical wireless or free space optics (FSO) plays an increasingly important role in our communication infrastructure as they offer gigabit per second data rates and low system complexity. The biggest disadvantage of terrestrial FSO links is that low clouds, dry snow and especially dense fog conditions entail heavy losses to the optical beam transmitted in the terrestrial free-space....
Interest in free space optics (FSO) has gained enormous popularity over the last few years, mainly due to two reasons, firstly delivering data rates that can meet future broadband telecommunication requirements and secondly as an alternate technology to solve the last mile access gap. However, optical signal transmitted in free space is subjected to deterioration while propagating due to its interactions...
The effect of snow on a FSO link is here addressed both theoretically and experimentally. Data collected during the snowfalls occurred in Milan, Italy, in the winter time of 2005 and 2006 are presented and discussed. It is shown that attenuation due to snow is not at all negligible because it could largely exceed the one caused by heavy rainstorms. Further, as in the case of rain events, the use of...
