More or less 15 Years have elapsed since we started our research works on power-line communications in Japan. We considered power-line communications to be an application field of the spread spectrum technology. Our fundamental idea was that for a clear transmission medium such as coaxial pair and/or optical fiber relatively simple modulation techniques can be applied. On the other hand for a hostile medium such as electrical power-line and/or urban mobile radio environment an exquisite modulation technique will be required and the spread spectrum modulation technique seems to meet the requirement well in a broad sense. The more an exquisite technique is required the more seductive it is for us communication researchers. This is why we started our study on power-line communications. At that time several manufacturing companies as well as the Japanese Post Office Ministry worked enthusiastically toward making the plan for the power-line home bus system. And in that plan a commercial spread spectrum power-line home bus system has been developed by NEC Home Electronics, Ltd. To my regret during that time there was not so much demand for the technology. In Japan people did not want such a low-price technology in the past prosperous age.

However, from the point of view of the environmental ecology utilization of existing infrastructure is considered to have growing importance in the coming age as a CO2 reduction technology.

To be prepared to the coming age further progress will be required for the power-line transmission technology. Transmission environment for power-line communications seems much worse than that for mobile communications, so that, not only to utilize existing high technologies but also to create novel technologies will be needed.

From these view points continued promotion for the research activity started last year in Essen is truly desirable. From the reason I intended to invite the 1998 International Symposium on Power-line Communications and its Applications to Japan.

Finally I would like to express my hearty thanks to persons who encouraged and supported me and also to The Telecommunications Advancement Foundation in Japan for their financial support.
