Free Space Optical Communications: Channel Modeling

Abstract

A terrestrial free space optical communication link using a commercial system was deployed across Faculty of Technology campus in Limeira. Channel measurements were collected in order to develop appropriate communication channel models. Unlike previous work, the link distance is very short (around 91 meters). Still, it was possible to observe significant scintillation index variations over a day. This behaviour agrees with previous results obtained in the literature for much longer links.
