Extending the power line LAN up to the neighborhood transformer

This article reports on the performance of audio, video. Multimedia and other high-data-rate in-home networking applications. The article starts by describing the problem, encountered in power line communication channels in terms of frequency response and noise characteristics and explains how in-home power line LANs can be extended to the neighborhood transformer. OFDM physical layers providing speeds of 45 Mb/s and 200 Mh/s as well as QoS and security are introduced. Finally, the results of large tests involving several thousands of nodes are described.
