Concept of developing a small system of subscriber access to a telephone line

Currently, the most affordable solution to the problem of telephone installation of remote objects is the use of small subscriber radio access systems and, in particular, telephone line radio extenders. The aim of the work is to develop a concept for the implementation of a radio extension device for a telephone line with automatic and remote selection of directions. The object of the study is a small subscriber access system. As a result of the study, recommendations were developed for developing a small subscriber access system.
