Stefano Galli received his M.S. and Ph.D. in Electrical Engineering from the University of Rome "La Sapienza" (Rome, Italy) in 1994 and 1998, respectively. In October 1998, Dr. Galli joined Bellcore (now Telcordia Technologies, an SAIC company) in Morristown, NJ, in the Broadband Networking Research Department where he is now a Senior Scientist. Dr. Galli's main research efforts are devoted to various aspects of xDSL systems, wireless/wired home networks, personal wireless communications, power line communications, and optical CDMA. His research interests also include detection and estimation, communications theory, and signal processing. Dr. Galli is an IEEE member, a reviewer for several IEEE journals, has published over 50 papers in peer reviewed international journals and conferences, and holds a US patent on Loop Qualification for DSL services. Dr. Galli also served as a Guest Editor for the IEEE Communications Magazine feature topic "Broadband is Power: Internet Access via the Power Line Network" (May 2003), and is currently serving as Technical Program Committee member for the 2004 Spring IEEE Vehicular Technology Conference (VTC'04), the 2004 IEEE International Symposium on Power Line Communications (ISPLC'04), and the 2004 IEEE International Conference on Communications (ICC'04).

Panel Summary:

Power line communications has been lately gaining more and more attention around the world. The attractive feature of using power cables as a communications medium is that there is a vast infrastructure in place that has a much higher penetration than any other wired solution. Despite the enormous potential, there is still some skepticism about the technology and its commercial viability due to several technical problems and regulatory issues that still remain to be solved. In this panel, we will discuss advantages and disadvantages of this emerging technology, focusing both on the technical challenges and on the commercial viability of power line communications as a means for broadband access and home-based LAN.
