Abstract
Importance of this study is caused by the fact, that development and implementation of Li-Fi communication technology to different areas of modern civilization are promising from the point of view of further development and wider using of digital technologies in everyday life, including such technologies, as a smart home and a city (settlement). The present state in the world of research of Li-Fi communication systems is analyzed. The main directions of the current developments are systematized. In this paper the information on the most promising applications of Li-Fi communication technology in the near future is considered and summarized. The conclusion is made that Li-Fi technologies can become a very promising alternative to traditional information exchange systems, and their applications can be very diverse. Li-Fi communication system in the field of view of the applied light radiation is capable to provide a big bandwidth, as well as a very high data transmitting rate between smartphones, tablets, laptops and other mobile devices. High security of Li-Fi technology in relation to attempts at unauthorized wiretapping is very important. Also, the argument in favor of research, development and implementation of the Li-Fi communication technology is the absence of electromagnetic radiations from the radio range. Intensive exchange by data streams in modern manufacture and necessity to ensure the insensitivity of a transmission channel to noise of a different nature and origin serve as a stimulus for the development of Li-Fi technology also. In addition, using of Li-Fi technology in manufacturing processes and technologies associated with the intensive data exchange, as well as in industrial automation systems, will reduce the weight of equipment and will increase the flexibility of its placement due to the failure from cables. Very promising prospects for Li-Fi technology appear in last years in education in connection with the modern technological movement of the formation of “Smart Classes”. Another important factor in favor of the development and implementation of Li-Fi technology is that for its deployment a license is not required, since the visible light range is a free band of the spectrum. At the same time, obviously, the development of Li-Fi technology faces with certain problems. Among them, an effective solution to the problem of filtration of interferences from external light sources, in particular, such as the sun should be distinguished. The problem of solving of difficulties caused by multiple reflection, which can produce the inter-symbol interference, is the very important as well.
