Високо-частотний зв'язок – ефективне рішення для сучасних комунікаційний систем

Abstract

The concept of communication system based on power lines (known as a PLC - Power Line Communication) is widely known for many years. The first attempts of implementation of this technology were taken in the first half of last century. However, because of the many problems resulting from insufficient level of science, this concept could not be used on a massive scale in paste. Now, after many years of research and made improvements, this technology became a viable alternative to existing transmission systems. Its dynamic development can be seen particularly in recent times, because big amount of existing electricity networks allows to use PLC in many telecommunication services such as Internet access or digital telephony. Communisation medium for PLC technology already exists in most applications (like cars or buildings), so the biggest advantages of this technology are reduction of wires and costs required for its implementation. These advantages make this technology an attractive solution for industrial networks. This argument encourages to have a closer look at the PLC standard and make an attempt to design projects based on it. In this article author will propose a simple communication system based on PLC technology.
