Re: How nice of PowerGrid...
said by bmn  :So, they will gladly make concessions of the HAM operators of the area, but to hell with you if you happen to be a shortwave radio or AM time signal listener ? Nice, real nice. I didn't read them say that. They'll "make concessions" to those that complain, like HAM's, because Part 15 rules they have to. If a shortwave radio or AM time signal listener exists in the area, and they complain, under those same rules they'll need to address it, too. But if no one complains, then there can be no "harmful interference". And a Part 15 operator needs to mitigate harmful interference, not hypothetical interference.
And realistically, how many in their area will use shortwave radio, especially these days when you can stream thingsw from all over the world. And if no one's using it in this area, why waste the spectrum and stop it from being used for Part 15 applications? In the view of the FCC, spectrum should be utilized to the fullest extent. | |

That would be a valid point if this Part 15 technology actually used the spectrum. The kicker has always been BPL just radiates energy into wireless spectrum, it doesn't actually use it to provide the service.
I'm all for maximum spectrum utilization as well. The problem with the FCC's concept of this is it is an unlicensed anarchy where the most robust interferer gets the most use of the spectrum. BPL sets a precedence whereby HF spectrum in any given area will require "clearing out" before it can be used by anyone. This would be somewhat reasonable if you could expect a BPL carrier to act within days or hours. History has shown us most carriers move at glacial speeds and often deny interference.
Parts of wireless spectrum often fall out of favor when other bands become "sexy". Hams were kicked out of LF and MF when the government began to regulate radio, thinking that HF was useless. Hams discovered HF was actually more useful than the lower bands. HF use declined over the decades as VHF and UHF were more suited for local communications and now the Internet carries regional and international information. However, I think you'll see low band VHF become more popular again as UHF frequency congestion becomes more of a problem. HF still makes a simple and cost effective national network that doesn't require infrastructure. My point is that it's foolish to ruin a wireless band with the proliferation of RF polluting devices as these bands may become more valuable in the future. | |
