Recently Broadband over power lines (BPL) has received much attention in communication technology and this is due to economically of sending high data rate services by re-use of power line cables. As data transfer via power lines to final consumer is one of the growing technologies, this study discusses the modeling and optimization of data transfer via power transfer lines and feasibility and adaptation of using this technology in Gilan are investigated. Finally, a model is evaluated for power lines by selection of a cable in selected area (Gilan province) as high speed transfer media and by investigation of the effect of different loads on channel feature, simulation and transfer function between various areas of network are considered. Simulation is done by ABCD transfer matrix and channel frequency response is achieved. This model is useful in description of frequency response of lines of this network and application in design of data transfer system.
