Abstract

This article is devoted to the consideration of the features of building transport networks of a mobile operator of 4G/5G generations based on wireless optical communication channels. The features, as well as some basic parameters characteristic of 4G/5G mobile communication networks, are considered. The article highlights the characteristics, architecture that are expected for fifth generation communication networks, and additionally provides a development roadmap. The need for 5G optimization of the entire network in general and transport networks in particular is substantiated. It is shown that satisfaction in the growing data traffic is possible with the use of new, competitive solutions by mobile operators. It has been found that the most effective solutions to the problem with increasing traffic are free space optics (FSO), which provide better scalability, deployment speed and cost efficiency, no frequency authorization is required. The possibility of using wireless optical communication channels as a Fronthaul network in 4G/5G is shown. In practice, the calculation of optical radiation losses is a laborious process. Therefore, these values are approximately replaced by the meteorological visibility range parameter. Based on this parameter, you can calculate the average availability of the communication channel. associated with the geographic region under study. For the meteorological visibility range, a practical example of an automatic method for approximating the integral distribution function for the case of the Andijan region, performed using MATLAB, is given.
