STUDY OF THE MOST IMPORTANT FACTORS AFFECTING ON EFFICIENCY OF POWER LINE COMMUNICATION SYSTEMS

Abstract

Due to the increasing demand for communications services, particularly the application of broadband multimedia services, it has become necessary to search for easy, low cost and reliable communications with information security. Communications via power lines PLC have become an attractive environment for communications services because of the power grid covering large areas of the world. This research will discusses the most important factors affecting the efficiency of PLC systems, and will focus more on distance between modems and change in load within the network. A set of modems has been connected to the local area network LAN, performing the tests at different distances, then switching the load and observing changes in system efficiency. The practical results have shown that the long distance had a negative effect, also the change in load has a significant negative impact on the rate of transfer of information and efficiency, as described later in the practical section. Therefore requires further practical research and full knowledge of other challenges that currently limit their widespread commercially PLC application.
