Take advantage of interference! (just a thought)

This may be stupid, but why not figure out away to turn this interference into usable broadcast? - Use the power grid as a broadcast antena...

Good observation. This concept has been used in the past to broadcast AM signals and is called Carrier Current. RF energy is coupled to the power lines and it radiates it out to listeners.

There are probably some unlicensed stations still using this technique today. At the very least, it disproves the claims by BPL proponents that power lines don't radiate radio signals.

Re: Take advantage of interference! (just a though

That's exactly what's happening. Unfortunately, it's screwing up licensed broadcasting. And people seem to forget that it's a two-way street. If I go on the air, I'll not only have to put up with wide-band noise, I'll probaly take down every Internet connection within half a mile that's using this crummy technology.
It's badly thought out, and just another way for companies to try and make a buck. I don't mind companies trying to improve their profit structure, but they should think about what they're trying to do, and the other ramifications it can have.
