Hi All. I've been asked to help with a bit of background research for an idea a friend of mine had. He wants to do some data over powerline transmissions. This isn't long distance (it would be within the same building). A few years ago I would have said that it wasn't going to be that possible, but with the number of broadband over powerline devices and the plethora of home networking extenders that use power lines, maybe things have changed? I've been doing some searching around, but as with most things network related, I'm not finding a ton of really useful info out there. Then again, maybe I'm just missing it. His specs aren't too demanding. Speed is somewhere between 100-300kpbs. Might be able to tolerate lower. Bi-directionality is a plus. Low cost is also a consideration, so if there are expensive transformers or the like involved, that might not be too good. I'm going to keep searching, but if anyone has any pointers, even just to manufacturers that do this kind of stuff, I'd appreciate it!
