Estudio de la tecnología Light-Fidelity (Li-Fi) y su vinculación con comunicaciones 5G

Abstract

In the present final career project, a study of the new Li-Fi (Light-Fidelity) technology and its linking with 5G communications is realized. This study is divided into two parts. In the first part, the following topics are reviewed in detail: OWC (Optical Wireless Communications), mainly the performance and characteristics of Li-Fi which focuses simultaneously on data communication and lighting of the environment, for the transmission of data, it is studied the types of the physical layer of the IEEE 802.15.7 standard, which corresponds to the VLC (Visible Light Communication) technology, the different modulation and multiplexing techniques, the internal configuration of the first transmitter and receiver chip, optical wireless channel and its modeling methodology, the multiuser access, and the study concludes with the differences between Li-Fi and VLC. In the second part of the research, it is analyzed the 5G communications, IoT (Internet of things) technology and intelligent lighting in order to understand how the advantages and characteristics of Li-Fi are related to these three topics. Moreover, it is established that Li-fi is an option to comply with the objectives and performance indicators of 5G communications. Finally, this study concludes with the identification of the unresolved problems of Li-Fi and the proposal of future studies related to this new technology.
