A channel model suitable for multi-wire overhead medium-voltage lines is proposed. This model is then employed in order to evaluate the multipath channel impulse response and the associated transmission capacity limit in actual overhead medium-voltage power distribution networks for broadband power-line communications applications. Electromagnetic interference limitations of such systems are discussed.

    • "Transmission of broadband over MV overhead power lines has been studied and reported on in the literature (Amirshahi et al, 2005), and the related area of transmission of broadband over Low Voltage (LV) (Amirshahi et al, 2006) has also been studied. Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) are important issues (Amirshahi et al, 2005, 2006) among others, such as how signal is coupled to the lines and the propagation constant of the line itself. The problem can be described as wave propagation on a transmission line (Pozar, 2005), for which the traveling wave can be analyzed by use of the voltages and currents travelling in opposite directions on the line.

    ABSTRACT: For years, some African universities followed the British education system, but this is gradually changing. For example in Ghana, the three terms to the year approach has been changed to the two semester approach. Also, local conditions and the service learning approach are being included in the curricula. This is being done in the Telecommunications Engineering program at Kwame Nkrumah University of Science and Technology. The program is planned such that some student projects for which the students will earn credits will result in products that will supply community needs. The program is therefore community-centered and provides community service. One project using this approach is based on Broadband Powerline Communication (BPL). BPL can be used in electronic learning at schools and to disseminate information to the community at large. It will empower the people and lead to improving their standard of living. It can also help the nation to become a full participant in the global community, while benefitting from the global economy. This paper describes how this project was designed to suit service learning through an experiential teaching method.

    ABSTRACT: Technologically developing countries lag far behind the leading nations, such as the United States, in many aspects of national interest; technology is one such area. In their effort to develop, these nations are faced with improving their technical support for running their countries. Technologies being employed in the leading nations are at the cutting edge; for a developing nation, catching up means a major jump in their technical applications to the cutting edge. This forces many developing nations to be user nations by simply acquiring the technologies employed in the first world nations for their own use. To provide relevance for students, there is the need to position them at the point where the cutting edge technology can be assimilated. This is necessary if they are not only going to operate the pieces of equipment, but if they are also going to service and maintain equipment in good working order. As the student in a developing nation graduates and enters the work environment, a question that comes up is, "What contribution can I make to the ongoing process of development?" For the telecommunications student, one obvious answer is ensuring that people in rural and remote areas can also have access to information that those in urban areas have access to for development. This paper discusses the endeavor between Pennsylvania State University Wilkes-Barre and a class of students in a telecommunications program at Kwame Nkrumah University of Science and Technology (KNUST) in Ghana. The approach used engages students in projects that focus on the appreciation of their unique role in helping with the development of their nation.
