About the book
With the widespread commercialization of the fifth generation (5G) wireless networking techniques, more and more attention is paid to the 5G evolution and even potential sixth generation (6G) wireless techniques. As one promising candidate technique, optical wireless communication (OWC) and its other specific paradigms including visible light communication (VLC) and free-space optics (FSO) are actively discussed in academic and research communities. In the coming beyond 5G & 6G envision, to meet unprecedented throughput need, wireless networking techniques will be further reshaped and extended to adapt to diverse indoor, outdoor, underwater, vehicular, aerial, underground, and railway applications scenarios. It should be noted that abundant unregulated available optical spectrum, natural high security, and no conventional radio frequency (RF) interference are among the distinct advantages of OWC. On the other side, there are many open problems that are still waiting for sufficient investigation and schemes iteration. Moreover, various OWC performance enhancement and channel characterization are urgently needed from the conventional Lambertian optical beams to the different scenarios-oriented non-Lambertian beams configuration.
All the relevant work will definitely open new improvement degree of freedom and push the OWC-based 6G access forward aggressively.
