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.

Yeah, and the really annoying thing is that they end up with "demo" projects that all use BPL for "last mile" connections in urban areas, while people don't realize that trying to use it over long distances in rural areas is a wholly different application.
Why is rural different? Well, when you are cramming a broadband signal down a wire designed for something other than broadband, there are significant losses with increasing distance. (Hint: consider DSL.) Additionally, there are transformers to consider, and the wire cable is even less suited to high-frequency transmission than twisted pair copper. (Yes, I know you thought that wasn't possible, but it is.)
Anybody got any results from any "long-haul" trials of BPL?

said by Topmounter :Define competition... Every state where I've lived or have friends in in recent years has DSL, Cable Modem and Wireless service available (satellite is also available, but I'd have to be pretty desperate to consider that a viable option). Your statement is very partially true..... every state may have 1 or more of those options in *A* part of the state, but there is NO state that has one or more of those options in *EVERY* part of the state.
There are a HUGE amount of areas where there is zero broadband options still, and it will continue this way because so many people in the non rural areas just can't comprehend why 'farmers' need broadband anyway..... can't seem to understand that 'farmers' are a small portion of rural settlers.....
What ever happened to the dream of working from home, no matter where you live?? I'm doing so in the Ozarks in Arkansas, but because I don't want to live in a 'city' or 'town', I have to do so with dialup.....
Satellite doesn't count, that only works if you want to pay a large monthly fee to get email and surf websites occasionally, most times at slower speeds than dialup....

the FCC needs BPL to be a "viable competitor" in the broadband space so they can continue to spout the fiction that there is "broadband competition" in the U.S. |

| Yes this is true the FCC continues to blow off the interference issue. They continue to flatulate about BPL being a major provider and they are still fantasising the it will be the rural provider.
