Optical Wireless Communication: A Candidate 6G Technology?
IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences, 2021 SUMMARY We discuss herein whether an optical wireless communication (OWC) system can be a candidate for post 5G or 6G cellular communication. Almost once per decade, cellular mobile communication is transformed by a significant evolution, with each ...
