Обзор ключевых особенностей при построении подводной оптической беспроводной связи

Abstract

Increased interest in the researches of the underwater environment of the oceans is required for the study of flora and fauna, the ocean floor, the search for minerals, monitoring existing oil rigs and other objects in the ocean, collecting the necessary information. All this cannot be done without high-quality and reliable communication in underwater oceanic conditions. Known methods of organizing underwater wireless communication considered communication systems using acoustic, radio frequency and optical waves. Foreign and Russian researchers note that underwater acoustic and radio frequency wireless communication is characterized by a low speed of information transmission and high latency, but at the same time, it allows you to transmit information over long distances. The need for high-speed information transmission has contributed to the development of underwater optical wireless communication. It allows you to organize communication at a high speed of information transmission with low latency over short distances. An increase in the communication range may provided with the help of network technology for building such communication systems. Purpose: the purpose is to review the scientific works of foreign researchers in the analysis of theoretical and experimental research in the field of underwater optical wireless communication. Results: It is shown, that underwater optical wireless communication maybe organized directly between the surface station and optical nodes, or using network technology to build a network to organize a multi-level communication system from the surface station to the optical nodes using optical access points and/or optical base stations. The analysis showed that when organizing underwater optical wireless communication, the main influence on the quality and reliability of communication is directly exerted by the underwater oceanic environment. Practical relevance: of the work lies in the systematization of scientific works of foreign researchers on the problems of underwater optical wireless communication and use as a basis for future applied research.
