Re: dc area
The BPL being proposed here is in-premise BPL. A broadband backbone is brought to a building, then the Telkonet modems are used to transmit the signal inside the building, using the building's electrical wiring. For older buildings, especially, this can be a more economical alternative to running new wire.
It would be possible to do the same using the building's telephone wiring, but the telephone wiring does not run to every room in the building.
Because the Amateur Radio interference issue comes up in every discussion about BPL, it seems, I will add that the Telkonet system uses HomePlug technology, which has, by that industry's decision, turned off all of the OFDM carriers in the Amateur bands.
With about 6 million HomePlug devices deployed, I have not heard of interference reports involving Amateur Radio.
