| dc.description.abstract | The provision of the various broadband communications services in developed countries is usually not a very big problem since a number of options are available ranging from wireless technology, wire line networks. Recently many authors have studied the technology viable for communication in developing countries environment such as non- urban areas, municipality and low density in different environment, by reflecting the already available wireless technology adopted in some of urban areas and developed countries. Technologies, which have realized to be the candidates for communications in such areas, are VSAT/Satellite systems which at least can provide broadband services in different remote areas and municipality. But the indications in various developing countries like Tanzania show that the implementation of such technologies for a true broadband accessibility and at affordable price is still a problem. It has been proposed that to be able to have connections different initiatives are needed. There is one technology which could be applicable to developing countries due to its penetrations and might provide the affordability for broadband services in most of developing countries. The technology is power-line networks. The applicability of Broadband Power-line Communication (BPLC) for communication has been reported in different areas of developed countries. Moreover, a lot of problems still impede the utilization of such infrastructure. This thesis is attempted to solve various problems whereby new Transfer function (TF) channel model and new model for current/voltage distribution are developed. In addition, by using the developed TF the channel capacity, the effects of channel load impedances, line length and branches, including ground to the stochastic channel attenuation for indoor, medium voltage, and low voltage are investigated. It has been observed that the channel capacity of broadband power-line network is minimum when the channel is terminated in characteristics impedances. In addition the position of notches are branched line lengths and load impedances dependant. Finally the ground return causes the high attenuation in the BPLC systems. | en_US |
