Translated title:
Study of free space optical communications in the context of development and improving the performance of modern B5G and 6G mobile networks
Summary:
With the present Diploma thesis, we will attempt to analyze the modern wireless mobile networks B5G and 6G, examining in detail the possibilities of utilizing optical technologies, specifically FSO systems.
Initially, an overview of FSO technology is provided by analyzing key performance parameters (Link Budget, SNR, etc.), modeling of channel losses, and the challenges that must be addressed to enable its full utilization in modern networks. Next, a brief overview of the specifications of B5G and 6G networks is presented, and we discuss the challenges arising from the enormous demands regarding the number of connected end users, the volume of data being transmitted, transmission rates, latency, and energy consumption.
In this context, we examine the possibility of integrating FSO systems into existing terrestrial infrastructures of cellular networks and into aerial-space networks, in order to enable the creation of a communication grid that will provide greater reliability, coverage, and overall better performance in modern telecommunication systems, presenting various architectures that have been proposed in this direction, while simultaneously providing results with the performances achieved. Additionally, in that sense, there is a reference to future expansions of FSO systems, in order to overcome the challenges related to their integration and efficient operation in B5G and 6G.
