Preface

The symposium on "Power-Line Communications and its Applications" is a natural result of the discussions between members of our research group on digital communications, industrial contacts and energy providers interested in this particular field of communications. The great variety of applications and the falling of the monopoly position of the national telecommunication organizations are obvious reasons for an increased interest from industrial and academic research and development institutes. There are several interesting aspects connected with this symposium. We mention a few of them.

Firstly, we deal with a very complicated channel that mixes the nasty behavior of a power-line with that of a communication channel. We are still far behind the developments in ordinary telephony as far as communication speed concerns. In a period of twenty years, modern modulation techniques increased transmission speed for telephony with a factor of ten. Moreover, in recent years many research institutes concentrated on mobile communication systems like GSM. We expect that a symposium as this gives a stimulus to further investigate the power-line as a communication channel.

Secondly, an important aspect of power-line communication is the question of standardization. Since there are different international standards and power-line regulations, we also have a great variety of different products and applied communication techniques. It is interesting to compare standards and performances for the respective standards and systems. Like in consumer electronics, world-wide standards give the opportunity to develop low cost equipment.

Thirdly, we succeeded in attracting a high (60) percentage of industrial participation. We also very much appreciate the presence of our guests from Japan and the USA. It is the mixture that makes this symposium to a unique opportunity to discuss the various systems and stimulate research in the field of power-line communications.

I wish you a successful symposium with many interesting discussions, new contacts and new ideas.
