Keynote II: modeling of electrical power supply systems as communication channels

This paper presents a two part presentation in modelling of electrical power supply systems as communication channels. Part I presents access domain networks. In spite of DSL technology, using power lines for broadband access is still of great importance all over the world. Although there are various and significant differences in structure and topology of power supply systems, a set of common elements and parameters can be found for a general description of power lines as communication channels. Part II talks about in-home and in-vehicle power line networks. There is today growing interest in the prospects of re-using in-building power line cables to provide a broadband local area network within the home or office. Besides the traditional access and home-LAN applications, PLCs also have other interesting applications. Today in the construction of vehicles, ranging from automobiles to ships, from aircraft to space vehicles, there is a power distribution system based on metallic conductors and this power distribution network may well perform double-duty, as an infrastructure supporting both power delivery and broadband digital connectivity.
