Abstract

This project aims to develop a tool for planning broadband data transmission systems via the electricity network infrastructure, using Power Line Communication (PLC) technology. This tool should permit the design of broadband systems, from the so-called last inch (internal network in the user’s environment), passing through the first or last mile, up to the backbone operator. The software tool to be developed will be integrated with a relational database and to a georeferenced tool for the planning of access networks to broadband internet. In phase 1 of this project, focused on the preliminary study and in the setting up of the system, there will be a need to analyze, among other things: the parameters of the signal-noise relationship, interference, bandwidth frequencies, transmission power and signal attenuation along the distribution lines in accordance with the topology. The noise characteristics of low and medium voltage distribution lines and their influence on the performance of PLC system will be evaluated. The system’s architecture will be totally object-oriented and the development environment will preferably be based on the use of open source software. PLC technology could help in meeting the challenges of broadband internet access in Brazil, including the inclusion of disadvantaged layers of society by means of the provision of services in areas and segments as yet uncatered for by networks and telecommunications services.
