Forget WiMax

Topic: Topic:

IBM and CenterPoint Energy will deliver broadband over power lines (BPL) in Houston.

It's an intriguing development for places like Phnom Penh, which have good electricity coverage, but generally crap phone systems, which means limited DSL.

I wonder, though, how clean the power has to be so that the noise doesn't overwhelm the broadband signal.

And wasn't Rolm developing this, oh, about 20 years ago, based on stuff invented by Dr Howard W Johnson?
