I've routinely used "ethernet over power line" communication. Given that this is possible and commercially viable, and somewhat similar technology is used throughout the power industry here in the U.S, I'd say there are numerous options available to you.
You do have to concern yourself with characterizing the lines, however. You have to know what the various classes and frequencies of unwanted signal (a.k.a. noise) on the line will be. These carrier current communication systems are widely available. Perhaps you should buy and try one that's intended for use in applications like yours. RE |
