Optical wireless links provide complementary behavior to the existing communication technologies like mmW or RF. It is admitted that the next generation of wireless communication networks (4G systems) will be based on multiple access technologies that will complement each other. Optical wireless is a very adequate access technology for future communication requirements and provides a huge bandwidth...
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...
Free space optics (FSO) links in the troposphere are highly dependent on different atmospheric effects, which vary according to different climatic conditions. For terrestrial FSO links, fog is the most critical of all atmospheric effects causing optical signal attenuations up to 480 dB/km in dense maritime fog environments and 130 dB/km in moderate continental fog environments. In this paper a brief...
