When a ﬁber-optic link is neither practical nor feasible, under the above scenario, wireless
optical communications (WOC) becomes a real alternative, since it allows to transfer data with
high-bandwidth requirements with the additional advantages of wireless systems (Arimoto,
2010; Ciaramella et al., 2009; Sova et al., 2006). Moreover, a wireless optical communication
system offers, when compared with RF technology, an intrinsic narrower beam; less power,
mass and volume requirements, and the advantage of no regulatory policies for using optical
frequencies and bandwidth....
