Ubiquity had some power line equipment on a newer standard that was sensitive enough that for many homes there were enough cables running in parallel the signals would propagate between phases enough to work. Some other vendors still sell the tech - it's come a long way from X10 in the '70s!
You also have plug in phase couplers that you can put wherever you have a 220v appliance like a dryer or range. Handy especially for older houses where running new cable can be a significant challenge.
- throwanem 3y agoTrue, but older houses are also less likely to have 220V runs in the first place, I think. That might be a Baltimore thing, though - not sure I've ever seen one in residential here, but this is also the city where municipal gas service was born, so it isn't a surprise for gas-fired ranges and dryers needing only 110V service to be ubiquitous here. I don't know if I'd want to depend on incidental capacitive coupling to carry signal between phases. I guess if it works it's likely to go on doing, but I feel like there's got to be some pretty sharp bandwidth constraints for noise, especially in residential...
