In central VA, IBEC (a BPL manufacturer) and the local rural cooperative are running a commercial BPL deployment. They have reported that they are sending a BPL signal down 13 miles of overhead lines, using repeaters, of course. The repeaters are purportedly as much as a mile apart, but a deployment map that shows the locations of the units shows the typical 1000 feet or so as the spacing for most of them. I have no specific data on any testing, although having talked with a couple of users there, they have been generally satisfied with the performance. One user complained about reliability.
With rural lines, they can generally go farther along the line than they can do in urban environs. There are far fewer transformers, taps and other lossy configurations, if they can clean up all the power-line noise.
