Abstract: This paper aims at introducing an old technology in a new way. Now-a-days the most common thing for control systems is the power line carrier communication. The main aim of our paper is transmission and reception of digital data from one place to another place with the help of PLCC modem through transmission lines without installing new wiring. A power line carrier system includes three basic elements transmission lines, transformers and coupling devices. Our main motto is that it can be established in remote areas with existing power lines with high data rate and less cost. Using the existing AC power lines as a medium to transfer the information/data it becomes easy to connect houses, offices etc with a high speed network access point.
