Like we don't have that today with powerline adapters?

I've been waiting to see real data about real problems. So far, there hasn't been much. My take on this whole BPL vs. the Hams is "proceed, with caution."

I became a ham because our inventiveness and innovations translate into real-world usage. This is a real-world usage. The ham bands are very important, but the Internet is the most important thing that has happened to the world since the invention of the printing press. We should do everything we can to support it, and if it affects the ham bands, it doesn't mean that BPL necessarily be sacrificed, it may mean that work needs to go into minimizing that interference.

I have experienced the interference from the BPL in westchester county NY when I operate mobile from there sometimes.

The noise literally wipes out all of HF. ]]> http://www.dslreports.com/forum/Re-electrical-stimulation-22314117 Wed, 29 Apr 2009 14:31:39 EDT Re: electrical stimulation http://www.dslreports.com/forum/Re-electrical-stimulation-22306949 said by funchords:

If it actually does ingress into Cable's supposed-to-be-closed system, if it does inhibit intended HF communication in ways that can't be mitigated, then it's a non-starter.

That it might have problems is not a reason to try.
It's only a non-starter if the "contributions" have not been paid to the local politicos that really run everything.]]> http://www.dslreports.com/forum/Re-electrical-stimulation-22306949 Tue, 28 Apr 2009 10:18:17 EDT Re: electrical stimulation http://www.dslreports.com/forum/Re-electrical-stimulation-22306440

I think you misunderstood RR User. The post wasn't about HAMs, it was about cable interference.

IBEC's BPL equipment has been shown to interfere with communications in the shortwave spectrum, that's according to the first link and pic posted. That also happens to be a big chunk of the return RF spectrum for cable systems, that's shown by the second pic.

In other words, using IBEC's BPL equipment will more than likely interfere with cable modem communications in the area. Is it worth trashing one data service to launch another?]]> http://www.dslreports.com/forum/Re-electrical-stimulation-22306093 Tue, 28 Apr 2009 04:05:40 EDT Re: electrical stimulation http://www.dslreports.com/forum/Re-electrical-stimulation-22305225

Notice where alot of shortwave spectrum is compared to the return spectrum used by cable.

Do you really want this product in wide deployment? They say not MANY have complained but then again they've only recently reached 1400 customers served, most of those in the last 18 months.

Would your really want to see the effects of the RF interference from MILES OF UNSHIELDED ELECTRICAL CABLE BEING USED FOR DATA TRANSFER JUST FEET AWAY FROM THE MAJORITY OF PHONE AND CABLE DISTRIBUTION SYSTEMS that are carrying the residential data traffic now?]]> http://www.dslreports.com/forum/Re-electrical-stimulation-22304438 Mon, 27 Apr 2009 19:36:03 EDT Re: electrical stimulation http://www.dslreports.com/forum/Re-electrical-stimulation-22304067 said by fifty nine:

Powerlines weren't designed for communications. They were designed to carry electricity.
The phone lines were not designed to carry digital data, but now they do.

The Cable TV system was not designed to carry digital data, but now it does.

Sending data over powerlines is like trying to send water through a pipe made of rolled up paper. Lots of messy leakage everywhere
I can't speak to that directly, but it probably has to be bad before it can become good. That's the way progress works.

Anything above a certain frequency would cause lots of interference.

Telephone companies: a provider of voice grade communications now offer internet.

Cable companies: a provider of premium television service now offer internet

cellular companies: a provider of cellular voice communications now offer internet

Why not the power companies?
then they will qualify for some of the Obama Bucks.
