Re: Gimme Speed Over The Power Lines!!!!!!!!!!!

said by SR_BMET:
I would guess that Power Line communications will be here sooner or later and without interference to Other Technologies.

Well, a new transistor isn't needed to make BPL interference free. The system from Corridor that uses 5 Ghz surface wave would not interfere with shortwave/HF radio spectrum. And realize there's plenty of conventional semiconductor devices today that work into the mult-gigabit/hertz ranges.

Putting gigabit communications on a power line is like building an F-16 on a Yugo chassis. By the time you get done enhancing and extending the Yugo chassis, you might as well have built an F-16 from scratch. FTTH can deliver more bandwidth to the home than will be needed in the next century -- it's the interference free "future proof" solution.

To rf_engineer and all, here is a link to Fogal's work.
There used to be additional information on some of the very interesting results from work he and people with him were able to obtain but I need to Re-Find that information.
»www.eskimo.com/~ghawk/fogal_device/
One of the descriptions of tests they did was of putting Video within a 5vdc line but using a signal that would not be detectable with your normal O'scope (1mv) and another where they showed extracting large amounts of additional data that was already available within a regular recorded video (VCR) tape.
This I found very interesting from the point of view of medical work.
Just some thoughts out loud but I would hope Fogal does get some Credit down the road for his work.
eom.
