The increase of technology and information turn the computer in a very necessary tool. Every day more people search for new forms to interconnect these computers in networks to obtain the best productivity and performance. The PLC technology opens a new possibility in computer communications. This consist in use the electrical network installed in every modern house has a way to transmit information between different points of it. This project consist in communicate two computers across the power lines in a Home Area Network, using a specialized hardware (MODEM) and an evaluation software to know the communication errors in real time. First, the specialized hardware (MODEM) to communicate the computers across the power lines was designed and implemented. Next an evaluation of modems communication was made with different connections and noise sources to know how affect this factors the transmitted information. Finally, were identified some connections between two modems that favor a stable communication and other connections that produces a deteriorate transmission process. Also were identified some electrical devices that produces interference and affect the communication across the power lines.
